| | 5 | Target : To Keep track of the statistics of how long it takes to upload files, |
| | 6 | and to report results and then to use that info to improve compute deadlines. |
| | 7 | |
| | 8 | The absolute time taken for upload of files is calculated |
| | 9 | (i.e. from the moment first file upload begins to the point where all uploads have completed). |
| | 10 | In order to calculate this time, in class **ACTIVE_TASK**, |
| | 11 | a variable is added as //bool first_upload_started//. |
| | 12 | Initially its value is set to **false**. |
| | 13 | Now in the function //upload_notify_app(const FILE_INFO* fip, const FILE_REF* frp)//, |
| | 14 | after //send_upload_file_status = true//, if //first_upload_started// is **false**, |
| | 15 | then it is set to **true** and the current time is recorded. |
| | 16 | This acts as the start time. |
| | 17 | Then for the end time, in class **RESULT**, |
| | 18 | as the return value of //is_upload_done// becomes **true**, |
| | 19 | that point of time is the end time, and the difference between these times acts as the upload time. |
| | 20 | With this value of time, |
| | 21 | an exponential average of times is maintained in order to get a usable value for improving compute deadlines. |
