Re: Is there a limit on tasks in progress? My cruncher is hungry!

Puzzling. Maybe the on_frac / active_frac values are screwed up on the poorly buffering one. Check client_state.xml. For a 24/7 machine [last 10-14 days], the values should be near 0.999000. The other is of course if the actual storage space for BOINC is less than the settings [event would tell how much net can be used]. The lowest of the 3 possible applies, so if e.g. there's 2.2 GB free, but same time it's specified to leave 2.0GB free on the relative partition, the actual storage cannot exceed 0.2GB.

Re: Is there a limit on tasks in progress? My cruncher is hungry!

Very yes on 0.999878 :D

But, there's too

<gpu_active_frac>0.000623</gpu_active_frac>

BOINC is supposed to maintain buffers separately for CPU and GPU, but JIC, would stop the client, edit that one to 0.999000 and start again.

Re: Is there a limit on tasks in progress? My cruncher is hungry!

I have a single core machine running windows 7 with a one day buffer and OET exclusively.
I have never had more than 2WU at any for the last 8weeks.
Go figure

SekeRob, I should edit <gpu_active_frac></gpu_active_frac> to

<gpu_active_frac>0.999000</gpu_active_frac> ?

Theodolite, it seems that I am not the only one with this issue.

Re: Is there a limit on tasks in progress? My cruncher is hungry!

Interesting ! Since the OET1 WUs require more time (about 1 hour or longer), the buffers of the both hosts fill up again in a very similar way.
Maybe the distribution of multiple short WUs (between 10 and 20 minutes) over several days makes the buffer management more challenging for fast systems ... ?
Thank you again for your inputs.
Cheers,
Yves

The great disparity in the length of the OET1 units wreaks havoc with the buffers. I leave mine set at 1 day. When I get those onslaughts of short units I end up with enough units to last 3 or 4 days as the units get longer. It eventually works itself out, but it boomerangs around a bit.

What CPU is you 'single core' exactly, and what -actual- runtimes [elapsed]? Just copy/paste your result list from here http://tinyurl.com/3448g5 in a reply.

Never had, never have trouble getting OET when set to exclusive. Either they fill the buffer properly, or they are limited to 35 per core if they run really really short, but those bouts never take too long [does not persist]. If you want them, you can get them, as the below last 7 day project stats show with a high on April 17 of 365K results validated:

Re: Is there a limit on tasks in progress? My cruncher is hungry!

The system is in a remote location. I am reasonably certain it is on 24x7, but I have no control over that. Set to use 100% of processors, 90% CPU time. Lifetime stats on this unit are:

xxxxx 04/24/2015 12:11:00 2:314:04:17:38 2,004,090 4,770

Given that the install date is 09/28/2010 16:35:02, maybe the issue is that it is being turned off overnight/weekend and I didnt realize that.

Re: Is there a limit on tasks in progress? My cruncher is hungry!

Absolutely. The amount of buffering is prorated to the actual average up-time per unit of time [24 hours] in the values the client maintains as posted by vcd683s above. If the on_frac is for instance 0.500000 [12 hours] and the active_frac of that is 0.500000, half of 12 hours the client computes, the amount of buffered work is adapted to that. Maximum maintained with 24/7 over last 10 days, else the value is slowly decreased, based on actual uptime.

That said, not sure if partial computing percent goes into the equation, but would be surprised it would not, so if the "Use at most nn% of CPU time" is set to less than 100% [default profile is 60%], then that too has buffered work total impact.

Kind of [late] Spock logic.
