Folding Forum

I'm having a problem with the following WUs:

Project: 2677 (Run 6, Clone 27, Gen 45)
Project: 2677 (Run 4, Clone 31, Gen 45)

They are running on two Fedora VMs on a q6600 running XP-64. Normally the frame time is 9.5 min. Now it is 12.5 min.

Tried deleting fahcore. It was downloaded fresh on each and they both are still going slow.

I also thought it was related to system issues I was having, so I built a new boot drive. No change.

System monitor shows both virtual cores being used on the VMs.

I thought I already answered you. EVERYBODY has this problem. It's caused by the new 2.10 core. You can stop trying to fix it, because you're just wasting your time. I have 8 VMs running notfred's that are all down about 10% on speed/PPD.

All we can do is wait for the next core.

Obviously I didn't see your answer in the other post. Thought I had posted in the wrong thread so I started a new one.

Not sure I understand the situation. Was this 2.10 core not tested?

It was rushed through to correct the problem of WUs using only one core. It takes care of that by EUEing and sending a report. Unfortunately, the core doesn't seem quite as optimized as previous versions. As I said, I expect a better version after they get the bad WUs out of the system.

It's not unusual to have point drops after the release of new clients/cores/drivers. It all evens out in the long run, but causes frustration in the short.

Frustrations indeed. Thanks very much for the information.

Not everybody has this problem with the 2.10 core. I don't. It seems to be primarily affecting VM's and/or dual core procs.

The farther you are from native linux and 4 cores, the greater the problem. He had already posted he was using VM and 2 cores, and EVERYBODY using that setup has the problem, to one degree or another.

I'm really not trying to be argumentative and I do care that people are having a problem with the new core, but just because 20 people post about frame time increase and PPD loss with dual core proc under a VM, does not mean that EVERYBODY has this problem. It still needs to be qualified.

Yes, you are being argumentative. Fine, I'll rephrase.

There have been many reports, here and elsewhere, that the 2.10 core will cause a slowdown in folding, especially in configurations other than native linux and 4 physical cores per client. Dual cores, VMs, and quads with smaller L2 cache seem to be more affected.

The purpose of my first response was simple to reassure the OP he was not alone and this was a reported, and expected, result.

Just noticed my PPD had dropped on my two dual-core VMs. Found the answer I was looking for here. Thanks!
