Folding Forum

Posted: **Fri Jul 18, 2014 6:44 pm**

I'm trying to get F@H 7.4.4 running in a SLE vm on top of Xen. I have found that when I install the OS in fully virtualized mode, everything works as expected. However, when I install the VM as a paravirtualized guest, the folding client successfully downloads the work unit and begins folding but never makes any progress. Eventually the work unit fails as unstable. Any suggestions?

By the way, the same thing happens with less cpus assigned as well.

Interesting question that I have no answer for.

Posted: **Fri Jul 18, 2014 7:04 pm**

One more thing -- I'm suspicious that this is somehow network related since the paravirtualized network often behaves a bit differently than FV. Is there any way to debug this to find out if network binding is the issue? Maybe a higher log level?

Posted: **Fri Jul 18, 2014 7:20 pm**

Well, in posting this, I thought of a couple other ideas to try, and one of them worked. I switched the VM to a static IP address configuration (instead of dhcp) and it seems to be folding correctly now. I'm still not sure what caused the problem, but at least I have a work around. I'd welcome feedback if anyone has an idea why a static ip address would make a difference.

You have 116 CPUs. Are those virtualized CPUs that are mapped onto a smaller number of real CPUs? If so, that's your problem. There is no value whatsoever to running FAH on any number of CPUs which cannot be dedicated to the folding process. Performance degrades first, and then the virtual machine thrashes, trying to complete all 116 threads simultaneously, leading to a hopeless deadlock. [This may not be your problem, but I have to ask.]

How much RAM is available to FAH? Again, each of those 116 threads needs a segment of real RAM. How much of your 8 GB of virtual RAM map onto real RAM that's available on a semi-dedicated basis?

I would try using a smaller number of CPUs and find out if it works. Start with maybe 12 and then gradually increase the number until you find a point where problems start happening.

Anything is possible, of course, but I wouldn't count on networking being the problem. In the portion of log that you posted, FAHClient successfully uploaded and downloaded WUs. It then failed after it began to process the WU. At that point, it didn't need anything further from the internet until after the error.

No, the physical machine has 144 CPUs, and I have this VM pinned to 116 of them.

The VM has 8GB of dedicated physical RAM (no memory overcommit in this xen configuration), but I had given it as much as 64 GB before, with no change.

As I mentioned, I had tried as few as 8 vcpus with no change in behavior. It wasn't until I changed the network to a static configuration that it started working (even with 116 vcpus, although I had to spin up a different VM on that machine so it's now only running with 96).

bruce, How much RAM would you recommend per core?

Posted: **Fri Jul 18, 2014 11:21 pm**

FYI

My 64 core system running Ubuntu 14.04 natively uses ~62.5MB per core when folding bigadv for a total of ~4GB.

Are you really shure about 144 Cores?
Specification shows only 15 Cores/ 30 Threads per CPU - so you will get a max of 120 Cores . . .

One suggestion I would make for future runs is to avoid using the 116 setting. You had a number of immediate failures at the point the folding core would be splitting the processing up over the threads. As 116 is a multiple of a large prime number, 29, that is probably the cause of those failures. 112 might work better as the largest prime factor is 7. 7 is known to cause problems with some WU's, but may be okay with these bigadv ones. Another number that might work okay is 108, avoid 104 as that is multiple of 13.
