Project: 6892 (Run 570, Clone 3, Gen 61) - Run single cpu

[gannett]

Hi All

Just checking the folding boxes after the weekend and I see that Project: 6892 (Run 570, Clone 3, Gen 61) Protein: ALZHEIMER DISEASE AMYLOID is running single on just a single CPU core. I am really pleased to be working on this project just wish I could do more at the same time.

I think that the previous unit Project: 6892 (Run 570, Clone 3, Gen 60) was doing the same as I am getting intermediate checkpoints being written.

Looking at the Gen 61, most recent unit it's running FahCore_78.exe that was just downloaded for this project.

Is any one else seeing this unit run in just a single core ?

FahCore_78 never uses more than a single core. If you are expecting a smp assignment, you have to specify -smp as one of the command line flags. The log you posted doesn't show whether that flag was present at the time the WU downloaded, but it most certainly was not. The assignment server wouldn't have given you that assignment if -smp had been present.

Ah yes well spotted, looking in the shell history I don't see an -smp flag after last reboot.
Will run this one out with -oneunit and restart folding with -smp 8 as normal.

Thanks for nudge - I should have checked that.
