     3= Upload Statistics Monitoring in BOINC =
     4
     5Target : To Keep track of the statistics of how long it takes to upload files,
     6and to report results and then to use that info to improve compute deadlines.
     7
     8The 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).
     10In order to calculate this time, in class **ACTIVE_TASK**,
     11a variable is added as //bool first_upload_started//.
     12Initially its value is set to **false**.
     13Now in the function //upload_notify_app(const FILE_INFO* fip, const FILE_REF* frp)//,
     14after //send_upload_file_status = true//, if //first_upload_started// is **false**,
     15then it is set to **true** and the current time is recorded.
     16This acts as the start time.
     17Then for the end time, in class **RESULT**,
     18as the return value of //is_upload_done// becomes **true**,
     19that point of time is the end time, and the difference between these times acts as the upload time.
     20With this value of time,
     21an exponential average of times is maintained in order to get a usable value for improving compute deadlines.
