6. The integrated management system based on data exchange and transport encapsulation according to claim 5, wherein: the parallel computer system adopts an MPI parallel programming model, and the MPI programming function at least comprises the following components:
the MPI _ Init is used for initializing an MPI execution environment, establishing the relation among a plurality of MPI processes and preparing for subsequent communication;
MPI _ Finailize to end an MPI execution environment;
MPI _ Comm _ rank for representing respective MPI processes;
MPI _ Comn _ size, which is used to indicate how many processes in a group of processes, returns an integer error value.
7. The integrated management system based on data exchange and transport encapsulation according to claim 1, characterized in that: the encoding in the encoding module (141) uses ASCII codes.
8. The integrated management system based on data exchange and transport encapsulation according to claim 1, characterized in that: and the packaging module (142) is packaged by adopting a JSON data format.
9. The integrated management system based on data exchange and transport encapsulation according to claim 1, characterized in that: the JSON data format encapsulation process is as follows:
s3.1, acquiring a JSON format configuration file;
s3.2, reading the transmission file into a memory;
s3.3, searching a configuration rule corresponding to the transmission file in the configuration file, and if the configuration rule exists, entering S3.4; otherwise, entering a time-out retransmission mechanism;
s3.4, reading a transmission record from the transmission file;
s3.5, acquiring a rule, namely the name of a field according to the configuration file;
s3.6, acquiring the value of the field corresponding to the name, and writing the name/value into a temporary file;
s3.7, repeating S3.5-S3.6 until all configuration rules aiming at the transmission file in the configuration file are traversed;
and S3.8, repeating S3.4-S3.7 until all call ticket processing is finished.
10. The integrated management system based on data exchange and transport encapsulation according to claim 1, characterized in that: the working process of the timeout retransmission mechanism in S3.3 is as follows:
s4.1, sending an overtime retransmission request to the client;
s4.2, after a request or an uploading command is sent out, no response is received within a specified time, and the response is considered to be overtime;
and S4.3, continuously sending a timeout retransmission request to the client after timeout, and determining that the communication is unavailable if no response is received after retransmission for a specified number of times, so that the communication is ended.
