Message 1898444 - Posted: 1 Nov 2017, 0:13:39 UTC

My main crunch box is named seti, computers are visible. This box runs Linux, has (3) GTX 1060s, a Xeon E3-1270 v3 @ 3.50GHz CPU, and TBars latest "special" app with a SETI v of 7.8.3. Looks like my GPU average WU duration is around ~3.5min, with CPU WUs running much wider duration, hard to specify. Currently it's limited to (3) CPU cores, but that is leftover from the default app when GPUs caused a bit of CPU tax, might be able to dedicate the last core to crunching as well?

One big question, how to cache enough GPU work to sustain the Tuesday outages? The past two weeks I've run out of GPU work in the first ~3 hours of the outage. I've got my settings set to store 9 days of work with an additional 5 days.

Any other suggestions to further optimize my performance? app_config file is stock TBar.

This is a dedicated crunch box, so no need to spare the end user.

Many thanks,

IMO nope, Seti will only f=give you max 100 tasks per GPU.
IIRC I read somewhere in these fora that Pettri has done some trick to fool Boinic into thinking he has many more GPUs so he doesn't run dry.

The only way to get through the outage with the special app is to do some bunkering of tasks before the start by rescheduling. You can bunker up to 1000 tasks and not exceed the BOINC limit.

So could you point me to a url/message that describes "bunkering"?

Thanks,

You would start with the Rescheduler thread. Variations on Mr. Kevvy's original program by Jimbocous, Laurent and Petri have been created. You need to use Laurent's CPU2GPU script to properly bunker for Tuesday.
