Re: Beta CEP2 Mac and Linux test version 6.37
For the users seeing the very low efficiency is this only with running multiple workunits at the same time? Is anyone seeing this low efficiency while only running one CEP2 workunit?

Thanks,
armstrdj

Yes, I'm seeing it on two (2) different 2-core devices that are running only a single WU each.

BETA_E200532_749_A.25.C19H11N3S2Se.175.0.set1d06_1 Elapsed=12:24:12 CPU=02:37:08

BETA_E200531_796_A.26.C20H11N3S2Si.82.1.set1d06_0 Elapsed=20:27:33 CPU=07:17:17

Both devices are and have been showing CPU usage between 92%-100% for the WUs.

Aboslutly, I have a 2.4 single core no HT P4 and boinctasks is saying it is running at 10% cpu efficiency. Here is the unit:
BETA_E200532_795_A.24.C19H13NS2SeSi.180.3.set1d06_1 using beta11 version 637
Been doing this a lot ever since this project started.

Extreme loss of time occurs regardless of how many cep2 units you process at a time. For those of us that have the problem it happens every time. The time loss occurs at or around the time of a checkpoint. It is most noticeable at the end of 2 because that is the largest job. When job 2 finishes the percent complete will drop from 30 to 40 percent down to maybe 5 percent and the cpu time will drop from 3 to 4 hours down to less than a half hour. I have leave in memory checked but that is not an issue since it is not starting over. The workunit continues to crunch with no interruption.

The version of linux core will correct the problem If I use 2.6.32-24 or earlier I do not have any problems crunching cep2 workunits.

I am certain that it is more than just using a more recent kernel since most people seem to be able to crunch cep2 using more recent versions of linux kernel. Hardware also seems varied between those of us that have had trouble with these huge loss of credit for the time spent. One person was even trying different linux distributions with no luck until he went with an older kernel. There is more discusion in the "poor crunching on this project" thread under cep2.

The report I initially filed noted all 3 machines were running just one WU apiece, and after that report I changed the 'restrictions' setting to allow one per core.

With one per core this CEP2 beta came close to overheating the Q6600 (GKrellm reported its CPU temp at 158 and started beeping an alarm at me; with one WU per core running on the Einstein@home GC-S5R4 application, it's currently right at 138F).

The temps of the 2 AMD machines did not elevate nearly that much... about 5 degrees on the dual core, and 10 degrees on the Phenom II... over what they usually run with a mix of Einstein, Orbit, Docking, HPF2 and FAAH.

Re: Beta CEP2 Mac and Linux test version 6.37
I also do not see any help for the extreme time loss -- if anything it might be worse. BETA_ E200531_ 212_ A.26.C20H11NO2S3.217.4.set1d06_ 1-- shows 2.84 hours for me, 9.52 for my wingman. This was run on my slow Intel box, it was somewhere over 11 hours elapsed time.

Re: Beta CEP2 Mac and Linux test version 6.37
The final report, Linux Ubuntu 10.04.01 with kernel 2.6.32.26 bld 25, 11 results, gap times suffixed. Notably, those with the shortest gaps/highest efficiency, ran after the GUI crashed and did a Alt-F1 to get into a terminal and did some bashing to get the wifi going again and then monitored from remote. It's amazing how much a GUI can eat in time, so after digging "init 3" will be the command to run when not needing the glossing front end:

I'll be waiting on the 2.6.38 miracle kernel with new scheduler as "using" Linux with GNOME or Unity of KDE and all these front ends do not seem to bring out the best of the platform... good for industrial headless crunching.

FAIC, go with this release ASAP, regardless if not able to fix these weird excessive timelosses that some see with (un) certain kernel/hardware combos. 93% efficiency or better than 95% efficiency. AND this was running always concurrent with a 2 Beta or CEP2 / 2 Other combination on the quad for the whole of the Beta test.

Re: Beta CEP2 Mac and Linux test version 6.37
I have one of the systems that have the extreme time loss and I don't think that this problem should prevent this bata version from becoming the release version. The extreme efficiency problem is the same between the current release and the bata.

I still hope you will continue to work on this problem for future releases.

This is just a shot in the dark.
My installation is just a stock installation except I get my INTERNET from a city wide wireless service. There is not much support for wireless devices in linux. I needed to us my windows driver using Ndiswrapper which allows you to use windows wireless drivers in linux.
Just a hope that any information that may help locate the problem will help solve it.
