Message 35676 - Posted: 26 Apr 2011 | 8:13:34 UTC

Having just been off for a long Easter weekend, I was thinking about this, since I recall in the past having had a few tests expire (i.e. my client completed the task, but it was rejected when returned to the server as the task had expired and been issued to another client) when I am away for a few days and don't leave my machines crunching. I thought of a couple possible solutions/improvements that might help in this case:

1) Display the timeout on the pending_tests page - it's good to know how long I've had a test for, but if I don't know how long I've got left it's hard to know whether to abort it or not. From http://prime2u.com:11002/pending_tests.html it looks like I've got at least until ~7 days, but it's nice to be sure!

2) Allow users to reset/extend the timer on their tests e.g. by providing a reset/extend button/link on the pending_tests page next to each task. That way if I know I'm going to complete a task but not make the deadline I can get a bit of extra time (e.g. 24 hours, or some extra % of the original deadline).

3) Allow the prpclient to 'heartbeat' back to the server to let it know it's still working on a task. Every heartbeat should reset the clock on a task, so the task will only every timeout if the client is no longer working on that task.

Just some thoughts, it's a shame to lose a couple of days work (I am working on the GFN128K port, and tests take ~20 hours or so, on an i5 with hyperthreading, which is 2-3 days work since I only crunch in working hours on this machine. If you add in a 4-5 day long weekend, it's easy to miss a deadline). No idea how hard any of this would be to implement, but just something to think about!

Cheers

These are all good ideas. The first would be easy, the third medium, the second hard. The third requires multi-threading the client and would probably be good enough to address the other problems. The main issue would be that the client should tell the server when it thinks that it will complete the workunit. That would be very hard as the helper programs are not integrated into the client (and never will be).

I had an internet cut long time today, around 16h and my deadline of PPSElow was missed. No files were accepted anymore. I need a longer deadline of this around 3 days to get also a cache of some sr5.
