Re: [WCG] 8 Core Xeon not crunching at full capacity

said by ajeb See Profile :

This can't be this hard...lol.

I'm running 99.3% to 100% on all eight cores. My process list looks the same as yours. The only thing seems to be that I'm using an older version of BOINC.
I was running the same version of BOINC before, it was doing the same thing, so I downloaded the latest...

Now, I've been thinking a bit... When I got this new 8-Core Mac Pro, I was upgrading my main workstation from a 4-Core Mac Pro that was moved to another part of the office... Now, All I did was move the hard drive over, it booted right up and I didn't think anything of it. Everything else has been working fine.

Could the Kernel or something else not be handling the 8-cores properly because of this, and not letting a low priority process like BOINC access 100% of the cores when the system is idle?

Could an archive & install from the DVD's that came with the 8-Core (10.5.4) do the trick perhaps?

Laguna Hills, CA		 Try downloading the combo update for 10.5.5 which just came out yesterday. Perhaps there will be some magic in there for ya.

Your using all cores so the system knows they're there. I can't see why the kernel would be written to handle them all.

How about the EFI firmware update?

Repair permission?

Just throwing out things now...lol.

I've been reading message boards for other projects using MAC and compiled a list of the stupid things.

Are you using local preferences or web preferences? Things seem to run better for most with setting the preferences on the website of the project not locally. I set that up using the custom option of device profile on the WCG website. I have two profiles, one for my MAC, the other for my PCs. I found that Protein folding took forever to run and blocked it running on the MAC.

Screen saver set to never?
Run always in activity pull down?

I'll keep looking.

The MAC OS is based on UNIX, UNIX has an automatic process that will "nice" down any long running processes to stop them from taking over all processing, thus starving out other processes.

By "nice" I mean that the system will assign a lower priority to the process.

In UNIX all you would have to do is re-nice the process to a -1 and it would be ignored by the system.

Since I am NOT familiar with the MAC OS, I have no clue how you might change the process priority...

I hope this helps...

What i'll do when I have some free time is to install a fresh OS copy on a spare hard drive... I have a feeling it's got something to do with me just transferring the hard drive from the old Mac Pro.

1 edit		 Well, I had some free time today at work so I installed a clean copy of Leopard 10.5.4 (that came with the new Mac Pro). After installation, the first thing I did was Install Boinc...

After running the test benchmarks at 100% on all 8 cores, once all 8 work units of HCC populated the spots, it dropped down from 100% to 85%.

I'm at a loss for words. Is this beast of a machine simply not cut out for crunching? I don't get it...

Edit: I also have XP Pro installed on this machine, and I just rebooted into it and installed Boinc, and it's happily crunching on all 8 cores. WTF is wrong with the Mac version?

Like glennaxl suggested, all a search turns up for me is:

System Prefs
->Energy Saver
->Options
->Processor Performance

What happens when you set BOINC to only use 85%? What about 50%? What happens when you tell it to only use 4 cores?

There is no processor performance settings on the Mac Pro in the Energy Saver preferences.

When I set only 4 cores to crunch, they operate at 96%. When I set the cores to operate at 50%, they operate at 43%.

I tried both the 5.10.45 client from WCG site as well as the latest 6.2.18 from Boinc site directly. Both behave identical.

Good idea, I tried creating a profile with HPF2 only and assigned it to the machine. I reset the project and it only downloaded HCC WU's.

Does it take some time to kick in?

I reset the project, it cleared & downloaded new ones... isnt that the same thing?

Well I'll be a monkey's uncle! It's HCC that's screwy on this Mac. Once HPF2's loaded up they are crunching at full capacity!

Thanks a lot for the suggestion, Brian!!! I would never have guessed it.

My bad, I had an idiot moment there... I just realized that by having an account for crunching on WCG, it's also for their forums.

I replied to the thread Brian, thanks!

I switched over to all HCC units and was able to duplicate the 85% problem on my Mac Pro.
