[boinc_dev] Multiple sched requests
09/12/2009 04:19 with no output files
AM
Hello all,
I'm working on a project which is non-cpu-intensive and does not have
result
files (instead, all network communication is done by the app itself). This
causes an interesting phenomenon when a workunit finishes:
*20:29:27 AProject Computation for task pinger_15571_0 finished
20:29:27 AProject Sending scheduler request: To fetch work.
20:29:27 AProject Requesting new tasks
20:29:32 AProject Scheduler request completed: got 1 new tasks
20:29:35 AProject Starting pinger_15796_0
20:29:35 AProject Starting task pinger_15796_0 using pinger version 103
20:29:43 AProject Sending scheduler request: To report completed tasks.
20:29:43 AProject Reporting 1 completed tasks, not requesting new tasks
20:29:48 AProject Scheduler request completed*
As you can see, a task finishes and immediately a scheduler request is
done,
because there is no more work in the queue, however, the WU that has
finished hasn't yet reached ready_to_report state, so it is not reported.
Instead, it is reported on a separate sched request, as soon as the first
scheduler request (to fetch new work) is completed.
This would be fine if we were doing file uploads, because then the workunit
would not be ready_to_report until the file upload was complete, but in
this
case there is no file upload.
Tested with 6.2.19, 6.6.36, 5.10.45 - same issue, although it does not
always manifest itself. Some users have it more often, some don't at all.
