In addition, control node 110 may also store the identity and tag status of the programmable device.

The control node 110 may include a check interface, a scheduling module, and a database. When the control node 110 receives the virtual machine creation request, the check interface is called to perform authentication and parameter check on the virtual machine creation request, and after the authentication and the parameter check are passed, the scheduling module selects the computing node 120 meeting the creation condition of the virtual machine, and sends the virtual machine creation request to the computing node 120. When receiving the virtual machine deletion request, the control node 110 calls the check interface to perform authentication and parameter check on the virtual machine deletion request, and after both the authentication and the parameter check are passed, the control node sends the virtual machine deletion request to the computing node 120.

The output device 206 is in communication with the processor 201 and may display information in a variety of ways. For example, the output device 206 may be a Liquid Crystal Display (LCD), a Light Emitting Diode (LED) display device, a Cathode Ray Tube (CRT) display device, a projector (projector), or the like.

In a specific implementation, the computer device may be a desktop computer, a laptop computer, a web server, a Personal Digital Assistant (PDA), a mobile phone, a tablet computer, a wireless terminal device, a communication device, or an embedded device, and the embodiment of the present application does not limit the type of the computer device.

The memory 203 is used for storing a program code 210 for executing the scheme of the application, and the processor 201 is used for executing the program code 210 stored in the memory 203. The computer device can implement the method for updating the management unit of the programmable device provided in the embodiment of fig. 3 below by the processor 201 and the program code 210 in the memory 203.

Fig. 3 is a flowchart of a method for updating a management unit of a programmable device according to an embodiment of the present application. Referring to fig. 3, the method includes:

step 301: when a management unit update request is received, a first marking is performed on each of the installed plurality of programmable devices.

It is noted that step 301 may be performed by a programmable device agent component in the compute node.

In addition, the management unit update request is used for requesting to update the management unit of the programmable device, and the management unit update request may be sent by the operation and maintenance domain. A programmable device is a device with a large number of programmable cells, for example, the programmable device may be an FPGA or a CPLD. The management unit is a programmable unit for managing interaction between a user and an operating system in a plurality of programmable units included in the programmable device, for example, when the programmable device is an FPGA device, the management unit of the FPGA device may be a Shell.

Furthermore, the first flag is a flag indicating a programmable device that needs to be updated by the management unit, that is, the programmable device having the first flag is a programmable device that needs to be updated by the management unit.

Since the management unit update request is used to request to update the management unit of the programmable device, when the management unit update request is received, a first flag may be performed on each of the installed plurality of programmable devices to indicate that the plurality of programmable devices are all programmable devices that need to update the management unit.

In practical applications, after the plurality of programmable devices are installed in the computing node, an identifier of each programmable device in the plurality of programmable devices may be written into the database of the control node, where the identifier of the programmable device may be a number, a name, and the like of the programmable device, and this is not limited in this embodiment of the present application. In this case, when the first flag is performed on each of the plurality of installed programmable devices, the first flag may be stored in correspondence with the identifier of each of the plurality of programmable devices stored in the database of the control node, so as to implement the first flag on each of the plurality of programmable devices.

For example, a database of control nodes may have maintained therein a correspondence between programmable device identifications and flag states. For a certain programmable device installed in the computation node, assuming that the identifier of the programmable device is identifier 1, after the computation node installs the programmable device, identifier 1 may be stored in the corresponding relationship between the identifier of the programmable device and the flag state. Then, when the compute node receives the management unit update request, a first flag may be added to a flag state corresponding to the flag 1 in the correspondence between the programmable device identifier and the flag state, so that the first flag of the programmable device may be implemented, and at this time, the correspondence between the programmable device identifier and the flag state may be as shown in table 1 below.

TABLE 1

Programmable device identification	Marking status
		Identification 1	First mark

Note that, in the embodiment of the present application, only table 1 is taken as an example to describe the correspondence between the programmable device identifier and the flag state, and table 1 does not limit the embodiment of the present application.

Further, before step 301, the programmable device may be scanned at power-on, and the scanned programmable device may be subjected to a second marking.

Note that the second flag is a flag indicating a programmable device not assigned to the virtual machine, that is, the programmable device having the second flag is a programmable device not assigned to the virtual machine.

Since the programmable devices in the compute node are all in an initial state at startup and are not allocated to the virtual machine for use, the programmable devices scanned at startup may be marked with a second flag to indicate that all the scanned programmable devices are programmable devices that are not allocated to the virtual machine for use.

When the scanned programmable device is subjected to the second marking, the second marking may be stored in correspondence with the identifier of the programmable device stored in the database of the control node, so as to implement the second marking of the programmable device.

Step 302: and for a target programmable device in the plurality of programmable devices, updating a management unit of the target programmable device when the target programmable device has the first mark and the second mark or when the target programmable device has the first mark and the third mark, wherein the target programmable device is any one of the plurality of programmable devices.

It is noted that step 302 may be performed by a programmable device driver component in the compute node.

In addition, the third flag is a flag indicating that the programmable device to which the virtual machine is assigned has been deleted, that is, the virtual machine to which the programmable device having the third flag is assigned has been deleted.

Moreover, when the target programmable device has the first mark and the second mark, the target programmable device is a programmable device which needs to update the management unit and is not allocated to the virtual machine for use, and under the condition, the management unit of the target programmable device is updated, so that the service operation in the computing node is not influenced. When the target programmable device has the first mark and the third mark, the target programmable device is a programmable device which needs to update the management unit and is distributed to the deleted virtual machine, and under the condition, the management unit of the target programmable device is updated, and the service operation of the computing node is not influenced.

It is worth noting that in the embodiment of the present application, when a management unit update request is received, a first flag may be performed on each of a plurality of installed programmable devices, and then, a management unit of a programmable device having the first flag and a second flag may be automatically updated, or a management unit of a programmable device having the first flag and a third flag may be automatically updated, so that automation of updating of the management unit is simply and efficiently achieved without affecting service operation, and an effect of smooth update is achieved.

The operation of updating the management unit of the target programmable device is similar to the operation of updating the management unit of a certain programmable device in the related art, and this is not described in detail in this embodiment of the present application.

It should be noted that, when updating the management unit of the target programmable device, the management unit update result of the target programmable device may be generated according to the update condition of the management unit of the target programmable device, and the management unit update result may include update failure or update success. And then, the updating result of the management unit can be sent to the operation and maintenance domain, so that a worker can timely know the updating condition of the management unit of the target programmable device according to the updating result of the management unit and timely maintain or replace the target programmable device which fails to be updated.

Further, when a virtual machine needs to be created on the computing node, the marking state of the programmable device can be updated in the process of creating the virtual machine. Specifically, the second flag of at least one first programmable device in the plurality of programmable devices may be deleted and a fourth flag may be performed on the at least one first programmable device when a virtual machine creation request of the first virtual machine is received; creating a first virtual machine and allocating the at least one first programmable device to the first virtual machine for use; and after the at least one first programmable device is allocated to the first virtual machine for use, deleting the fourth mark of the at least one first programmable device, and carrying out fifth mark on the at least one first programmable device.

It should be noted that the virtual machine creation request of the first virtual machine is used to indicate that the first virtual machine is created, the virtual machine creation request may be sent by the control node, and the virtual machine creation request may carry the number of the programmable devices that need to be allocated to the first virtual machine for use, or may directly carry the identifier of the programmable devices that need to be allocated to the first virtual machine for use. Then, the computing node may determine the at least one first programmable device from the installed plurality of programmable devices according to the number or the identifier of the programmable devices carried in the virtual machine creation request, for example, when the number of the programmable devices that need to be allocated to the first virtual machine for use in the virtual machine creation request is 2, the computing node may randomly select 2 programmable devices that are not allocated to the virtual machine for use and are not updating the management unit from the installed plurality of programmable devices as the first programmable devices; or, when the identifier of the programmable device that needs to be allocated to the first virtual machine for use is identifier 1 and identifier 2 carried in the virtual machine creation request, the computing node may use the programmable device identified by identifier 1 and the programmable device identified by identifier 2 as the first programmable device.

In addition, the first programmable device may be a programmable device that is not allocated to the virtual machine and is not updating the management unit when the virtual machine creation request of the first virtual machine is received, for example, the first programmable device may be a programmable device having the second flag and not having the first flag.

It should be noted that the fourth flag is a flag indicating a programmable device to be assigned to the virtual machine for use, that is, the programmable device having the fourth flag is a programmable device to be assigned to the virtual machine for use.

Since the at least one first programmable device determined upon receipt of the virtual machine creation request for the first virtual machine is about to be allocated for use by the first virtual machine and no longer belongs to programmable devices not allocated for use by the virtual machine, the second flag for the at least one first programmable device may be deleted and a fourth flag may be placed on the at least one first programmable device to indicate that the at least one first programmable device is a programmable device for allocation for use by the virtual machine.

In addition, the fifth flag is a flag indicating a programmable device that has been assigned to the use of the virtual machine, that is, the programmable device having the fifth flag is a programmable device that has been assigned to the use of the virtual machine.

Since the at least one first programmable device is a programmable device that has been assigned to the first virtual machine for use after the at least one first programmable device is assigned to the first virtual machine for use, and is no longer about to be assigned to the first virtual machine for use, the fourth flag of the at least one first programmable device may be deleted and the at least one first programmable device may be marked fifth to indicate that the at least one first programmable device is a programmable device that has been assigned to the virtual machine for use.

When the second flag of at least one first programmable device in the plurality of programmable devices is deleted and a fourth flag is performed on the at least one first programmable device, the second flag in the flag state corresponding to the identifier of the at least one first programmable device stored in the database of the control node may be replaced with the fourth flag to delete the second flag of the at least one first programmable device and implement the fourth flag of the at least one first programmable device.

When the fourth flag of the at least one first programmable device is deleted and the fifth flag of the at least one first programmable device is performed, the fifth flag may be replaced with the fourth flag in the flag state corresponding to the identifier of the at least one first programmable device stored in the database of the control node, so as to delete the fourth flag of the at least one first programmable device and implement the fifth flag of the at least one first programmable device.

Further, if the virtual machine creation request of the first virtual machine is sent by the control node, before the control node sends the virtual machine creation request, the control node may further invoke a check interface to perform authentication and parameter check on the virtual machine creation request, and after both the authentication and the parameter check pass, the scheduling module in the control node selects a computing node that meets the virtual machine creation condition, and sends the virtual machine creation request to the computing node.

It should be noted that the virtual machine creation condition may be that the number of programmable devices in the compute node that are not allocated to the virtual machine for use and are not in the update management unit is greater than or equal to the number of programmable devices that need to be allocated to the first virtual machine for use, and of course, the virtual machine creation condition may also be other conditions, which is not limited in this embodiment of the present application.

Further, when the virtual machine needs to be deleted on the computing node, the marking state of the programmable device can be updated in the process of deleting the virtual machine. Specifically, at least one second programmable device which is allocated to the second virtual machine to use in the plurality of programmable devices may be determined when a virtual machine deletion request of the second virtual machine is received; deleting the second virtual machine; and after the second virtual machine is deleted, deleting the fifth mark of the at least one second programmable device, and carrying out third mark on the at least one second programmable device.

It should be noted that the virtual machine deletion request of the second virtual machine is used to indicate that the second virtual machine is deleted, the virtual machine deletion request may be sent by the control node, and the virtual machine deletion request may carry an identifier of the second virtual machine that needs to be deleted.

Since the at least one second programmable device is no longer in use by the second virtual machine after the second virtual machine is deleted, the fifth flag of the at least one second programmable device may be deleted and the at least one second programmable device may be flagged third to indicate that the at least one second programmable device is a deleted programmable device assigned to the virtual machine.

When the fifth mark of the at least one second programmable device is deleted and the third mark is performed on the at least one second programmable device, the fifth mark in the mark state corresponding to the identifier of the at least one second programmable device stored in the database of the control node may be replaced with the third mark, so as to delete the fifth mark of the at least one second programmable device and implement the third mark of the at least one second programmable device.

Further, if the virtual machine deletion request of the second virtual machine is sent by the control node, before the control node sends the virtual machine creation deletion, the control node may also call the verification interface to perform authentication and parameter verification on the virtual machine deletion request, and after both the authentication and the parameter verification pass, the control node sends the virtual machine deletion request to the computing node.

Furthermore, in order to enable the at least one second programmable device allocated to the second virtual machine to be allocated to other virtual machines for use again after the second virtual machine is deleted, after the fifth mark of the at least one second programmable device is deleted and the third mark is performed on the at least one second programmable device, the logic information of the at least one second programmable device can be cleared; and after the logic information of the at least one second programmable device is cleared, deleting the third mark of the at least one second programmable device, and carrying out second mark on the at least one second programmable device.

After the logic information of the at least one second programmable device is cleared, the at least one second programmable device is not already a programmable device allocated to the second virtual machine, so that after the logic information of the at least one second programmable device is cleared, the third flag of the at least one second programmable device can be deleted, and the at least one second programmable device is marked with the second flag to indicate that the at least one second programmable device is a programmable device not allocated to the virtual machine.

When the third flag of the at least one second programmable device is deleted and the second flag of the at least one second programmable device is performed, the third flag in the flag state corresponding to the identifier of the at least one second programmable device stored in the database of the control node may be replaced with the second flag to delete the third flag of the at least one second programmable device and implement the second flag of the at least one second programmable device.

Furthermore, the programmable device can be scanned every preset time length after the startup; when the last scanned programmable device comprises a third programmable device, deleting all current marks of the third programmable device, and after deleting all current marks of the third programmable device, carrying out sixth marking on the third programmable device; and when the scanned programmable device comprises a fourth programmable device, deleting the sixth mark of the fourth programmable device, and carrying out second marking on the fourth programmable device.

It should be noted that the third programmable device is a programmable device other than the programmable device scanned this time, that is, the third programmable device is a programmable device not scanned this time.

In addition, the sixth flag is a flag for indicating other programmable devices that are missing, that is, the programmable device having the sixth flag is a programmable device that has been missing.

Since the third programmable device is a programmable device other than the programmable device scanned this time, when the programmable device scanned last time includes the third programmable device, it indicates that the third programmable device is lost after the last scanning and before the current scanning, and the lost programmable device cannot be operated, so it is necessary to delete all current marks of the third programmable device first, and then perform a sixth mark on the third programmable device to indicate that the third programmable device is lost.

Furthermore, the fourth programmable device is a programmable device other than the programmable device scanned last time, that is, the fourth programmable device is a programmable device not scanned last time.

Because the fourth programmable device is other programmable devices except the last scanned programmable device, when the scanned programmable device includes the fourth programmable device, the fourth programmable device may have been scanned, but is lost during the last scanning, and is retrieved during the current scanning, at this time, the sixth mark of the fourth programmable device may be deleted, and the second mark is performed on the fourth programmable device to indicate that the fourth programmable device may be allocated to the virtual machine for use; or, the fourth programmable device may be a programmable device that has not been scanned before the current scanning, that is, the fourth programmable device is a programmable device newly scanned at this time, an identifier of the fourth programmable device may be written into the database of the control node, and then the second flag and the identifier of the fourth programmable device stored in the database of the control node are stored correspondingly, so as to indicate that the fourth programmable device is a programmable device that is not allocated to the virtual machine for use.

When the sixth marking is performed on the third programmable device after all the current marks of the third programmable device are deleted, all the marks in the marking state corresponding to the identifier of the third programmable device stored in the database of the control node may be replaced with the sixth mark, so that the sixth mark of the third programmable device is deleted after all the current marks of the third programmable device are deleted.

When the sixth flag of the fourth programmable device is deleted and the second flag of the fourth programmable device is performed, the sixth flag in the flag state corresponding to the identifier of the fourth programmable device stored in the database of the control node may be replaced with the second flag, so as to delete the sixth flag of the fourth programmable device and implement the second flag of the fourth programmable device.

It is worth to be noted that, after the programmable device is started up, the programmable device is scanned at intervals of a preset time, and when the last scanned programmable device includes a third programmable device, all current marks of the third programmable device are deleted, and then a sixth mark is performed on the third programmable device. And when the scanned programmable device comprises a fourth programmable device, deleting a sixth mark of the fourth programmable device, and marking the fourth programmable device for the second time, wherein under the condition, the use of the fourth programmable device can be restarted, so that the use efficiency of the programmable device installed on the computing node can be improved.

Step 303: and deleting the first mark of the target programmable device after the updating of the management unit of the target programmable device is successfully completed.

It is noted that step 303 may be performed by a programmable device agent component in the compute node.

In addition, after the management unit of the target programmable device is successfully updated, the target programmable device does not need to update the management unit, so that the first mark of the target programmable device can be deleted to avoid triggering the update of the management unit of the target programmable device.

In the embodiment of the application, when a management unit update request is received, a first mark is carried out on each programmable device in a plurality of installed programmable devices, and the first mark indicates the programmable device which needs to be updated by the management unit. And then, for a target programmable device in the plurality of programmable devices, when the target programmable device has a first mark and a second mark, or when the target programmable device has a first mark and a third mark, updating a management unit of the target programmable device, wherein the second mark indicates a programmable device which is not allocated to the virtual machine for use, the third mark indicates a programmable device which is allocated to the virtual machine and is deleted, and the target programmable device is any one of the plurality of programmable devices. And deleting the first mark of the target programmable device after the updating of the management unit of the target programmable device is successfully completed. The updating process of the management unit simply and efficiently realizes the updating automation of the management unit under the condition of not influencing the operation of the service, and achieves the effect of smooth updating.

2.

3. And the computing node creates a virtual machine, allocates the at least one programmable device to the created virtual machine for use, deletes the fourth mark of the at least one programmable device after the at least one programmable device is allocated to the virtual machine for use, and marks the at least one programmable device for the fifth mark.

4. And when the computing node receives a virtual machine deleting request, deleting the virtual machine, deleting the fifth mark allocated to at least one programmable device of the virtual machine after the virtual machine is deleted, and carrying out third mark on the at least one programmable device.

It should be noted that, after the third marking is performed on the at least one programmable device, the computing node may also clear the logic information of the at least one programmable device, so that the at least one programmable device may be allocated to another virtual machine for use again. And after the logic information of the at least one programmable device is cleared, the third flag of the at least one programmable device may be deleted, and the second flag of the at least one programmable device may be performed.

5. When the compute node receives a management unit update request, a first marking is performed on each of the installed plurality of programmable devices.
