具体而言, 所述转换器的处理端包括多个 CPU, 每个 CPU中包括转换不同格式文档的对 应转换程序。 当所述处理端到服务器访问待转换文档时, 获取自身各个 CPU利用率。 所述处 理端确定待转换文档分割的份数的方法为, 获取利用率低于某一预设值的 CPU个数, 则待转 换文档分割的份数为所述利用率低于预设值的 CPU个数, 其中所述预设值可根据实际应用确 定, 对此本发明不作限定。 所述分割后单份文档包含的页数根据待转换文档总页数除以低于 所述预设值的 CPU个数的商决定, 其中所述商取整, 即为分割后的单份文档应分配的页数; 余数为未分割的文档页数, 并添加至任一份已分割的单份文档中。 Specifically, the processing end of the converter includes a plurality of CPUs, and each CPU includes a corresponding conversion program for converting documents of different formats. When the processing end accesses the document to be converted to the server, it acquires its own CPU utilization. The method for determining, by the processing end, the number of copies of the document to be converted is to obtain the number of CPUs whose utilization rate is lower than a preset value, and the number of copies of the document to be converted is that the utilization rate is lower than a preset value. The number of CPUs, wherein the preset value may be determined according to an actual application, and the present invention is not limited thereto. The number of pages included in the divided single document is determined according to the quotient of the total number of pages of the document to be converted divided by the number of CPUs lower than the preset value, wherein the quotient is the whole document, that is, the divided single document The number of pages that should be allocated; the remainder is the number of undivided document pages and is added to any of the split single documents.
于本实施例中, 所述处理端计算分割后转换所述待转换文档的时间及直接转换所述待转 换文档的时间的方式为, 分割后转换所述待转换文档的时间包括启动转换环境的时间 Tl、 拆 分文档的时间 Τ2及转换原有单个文档的时间 Τ3。 则若将待转换文档分割为 Ν份, 分割后转
换所述待转换文档的时间 Tm =Tl*N+T2*N+T3/N。直接转换所述待转换文档的时间包括启动 转换环境的时间 T1及转换原有单个文档的时间 T3, 则直接转换所述待转换文档的时间 Τη= Tl+T3。 其中, 所述转换原有单个文档的时间 Τ3根据待转换文档的总页数确定, 即若单页文 档的转换时间为 Τρ, 待转换文档的总页数为 Ρ, 则 Τ3=Τρ*Ρ。 若分割后转换待转换文档的时 间小于直接转换待转换文档的时间, 则执行步骤 103c; 若分割后转换待转换文档的时间大于 或等于直接转换待转换文档的时间, 则执行步骤 103d。 In this embodiment, the processing end calculates the time for converting the to-be-converted document after the segmentation and the time for directly converting the to-be-converted document, and the time for converting the to-be-converted document after the segmentation includes starting the conversion environment. Time Tl, time to split the document Τ2, and time to convert the original single document Τ3. Then, if the document to be converted is divided into two parts, the division is followed by The time Tm = Tl * N + T2 * N + T3 / N of the document to be converted. The time for directly converting the to-be-converted document includes the time T1 of starting the conversion environment and the time T3 of converting the original single document, and directly converting the time of the document to be converted Τη=Tl+T3. The time 转换3 of converting the original single document is determined according to the total number of pages of the document to be converted, that is, if the conversion time of the single-page document is Τρ, and the total number of pages of the document to be converted is Ρ, then Τ3=Τρ*Ρ. If the time for converting the to-be-converted document is smaller than the time for directly converting the to-be-converted document, step 103c is performed; if the time for converting the to-be-converted document after the segmentation is greater than or equal to the time for directly converting the to-be-converted document, step 103d is performed.
步骤 103c: 若分割后转换待转换文档的时间小于直接转换待转换文档的时间, 处理端分 割后转换所述待转换文档。 Step 103c: If the time for converting the to-be-converted document after the segmentation is less than the time for directly converting the to-be-converted document, the processing end converts the to-be-converted document after the segmentation.
具体而言, 所述分割后转换所述待转换文档的方式为, 处理端将分割后的待转换文档分 别分配至利用率低于预设值的 CPU中, 并在所述 CPU中启动不同线程并发执行转换任务, 当 不同线程全部完成转换任务后, 处理端将转换后的文档发送至服务器保存, 所述服务器向客 户端发送完成通知。 于此, 处理端分割后转换或直接转换所述待转换文档时, 首先将所述待 转换文档转换成 PDF格式, 再将 PDF格式转换成图片或 swf格式。 客户端接收到完成通知后, 到服务器获取完整的图片或 swf文件。 Specifically, the manner of converting the to-be-converted document after the splitting is: the processing end respectively allocates the divided documents to be converted to a CPU whose utilization is lower than a preset value, and starts different threads in the CPU. The conversion task is executed concurrently. After all the threads complete the conversion task, the processing end sends the converted document to the server for saving, and the server sends a completion notification to the client. In this case, when the processing end splits or directly converts the to-be-converted document, the to-be-converted document is first converted into a PDF format, and then the PDF format is converted into a picture or a swf format. After receiving the completion notification, the client gets a complete picture or swf file to the server.
步骤 103d: 若分割后转换待转换文档的时间大于或等于直接转换待转换文档的时间, 处 理端直接转换待转换文档。 Step 103d: If the time for converting the to-be-converted document after the segmentation is greater than or equal to the time for directly converting the to-be-converted document, the processing terminal directly converts the to-be-converted document.
具体而言, 所述处理端直接转换所述待转换文档的方式为, 处理端查找自身利用率最低 的 CPU,对应启动所述 CPU中的转换程序直接转换所述文档,并当转换完成后发送至服务器 保存, 保存完成后, 服务器向客户端发送完成通知。 Specifically, the processing end directly converts the to-be-converted document in a manner that the processing end searches for the CPU with the lowest utilization rate, and directly converts the document by starting the conversion program in the CPU, and sends the file after the conversion is completed. After saving to the server, after the save is complete, the server sends a completion notification to the client.
举例而言, 若启动转换环境的时间 T1为 10ms, 拆分文档的时间 T2为 5ms, 转换单页文 档的时间 Tp为 0.5ms。 某一时刻, 客户端向服务器上传待转换的 word文档 A和 ppt文档 B (文档 A有 57页且优先级为高, 文档 B有 120页且优先级为中)。转换器的控制端排列两文 档顺序为先处理 A再处理 B,并将排序结果通知转换器的处理端,所述处理端根据排序结果, 先访问文档 A。 若处理端有 3个 CPU分别为 CPU1、 CPU2及 CPU3, 且访问所述文档 A时, 各 CPU利用率分别为: CPU1为 70%, CPU2为 40%, CPU3为 Ί%。 于此, 预设值为 70%, 利用率低于 70%的 CPU有 CPU2及 CPU3两个, 则处理端将文档 A划分为 2份 (第一份为 1-28 页, 第二份为 29-57 页)。 处理端计算分割后转换文档 A 的时间 Tl*2+T2*2+T3/2=10*2+5*2+(0.5*57)/2=44.25ms , 直 接 转 换 文 档 A 的 时 间 Tl+T3=10+0.5*57=38.5ms, 前者大于后者, 则所述处理端选择利用率最低的 CPU3直接转换 所述文档 A, 处理端完成文档 A的转换并发送至服务器保存后, 服务器向客户端发送完成通 知。
于上述实施例中, 转换器的处理端处理完成文档 A后, 接下来按顺序处理文档8。 若所 述处理端访问文档 B时, 各 CPU利用率分别为: CPU1为 9%, CPU2为 7%, CPU3为 72%。 此时, 利用率低于 70%的 CPU有 CPU1及 CPU2两个, 则处理端将文档 B划分为 2份, 第一 份为 1-60 页, 第二份为 61-120 页。 处理端计算分割后转换文档 B 的时间为 10*2+5*2+(0.5*120)/2=60ms, 直接转换文档 B的时间为 10+0.5*120=70ms, 前者小于后者, 则所述处理端分割后转换文档 B, 即相应启动 2个 wpp.exe转换程序, 一个转换程序放置于 CPU1 中用于转换第一份分割文档, 另一个转换程序放置于 CPU2中用于转换第二份分割文 档。 所述 2个 wpp.exe转换程序全部完成文档转换并发送至服务器保存后, 服务器向客户端 发送完成通知。 For example, if the time T1 for starting the conversion environment is 10 ms, the time T2 for splitting the document is 5 ms, and the time Tp for converting the single-page document is 0.5 ms. At some point, the client uploads the word document A and the ppt document B to be converted to the server (document A has 57 pages and the priority is high, document B has 120 pages and the priority is medium). The control end of the converter arranges the two document sequences to process A and then process B, and notifies the processing end of the converter of the sorting result, and the processing end first accesses the document A according to the sorting result. If there are three CPUs on the processing side, namely CPU1, CPU2 and CPU3, and accessing the document A, the CPU utilization rates are: CPU1 is 70%, CPU2 is 40%, and CPU3 is Ί%. Here, the default value is 70%, and the CPU with the utilization rate lower than 70% has two CPU2 and CPU3, then the processing end divides the document A into 2 copies (the first copy is 1-28 pages, and the second copy is 29). -57 pages). The processing end calculates the time T1*T2*2+T3/2=10*2+5*2+(0.5*57)/2=44.25ms after converting the document A, and directly converts the time T1+T3 of the document A. =10+0.5*57=38.5ms, the former is larger than the latter, then the processor selects the lowest utilization CPU3 to directly convert the document A, and the processing end completes the conversion of the document A and sends it to the server for saving, the server sends the client to the client. The end sends a completion notification. In the above embodiment, after the processing end of the converter finishes the document A, the document 8 is processed in order. If the processing end accesses the document B, the CPU utilization rates are: 9% for CPU1, 7% for CPU2, and 72% for CPU3. At this time, if the CPU with less than 70% utilization has CPU1 and CPU2, the processor divides document B into 2 copies, the first one is 1-60 pages, and the second one is 61-120 pages. The time for converting the document B after the processing is calculated is 10*2+5*2+(0.5*120)/2=60ms, and the time for directly converting the document B is 10+0.5*120=70ms, the former is smaller than the latter, then the former is smaller than the latter The processing end splits and converts the document B, that is, correspondingly starts two wpp.exe conversion programs, one conversion program is placed in the CPU1 for converting the first divided document, and another conversion program is placed in the CPU 2 for converting the second Split the document. After the two wpp.exe conversion programs complete the document conversion and send them to the server for saving, the server sends a completion notification to the client.
