Another 1.5MB download running on one core only. Log shows completion of previous WU with time remaining to deadline.

This WU was downloaded over 12 hours ago and still has 6 days 14 hours+ before it will complete (per FahMon 2.3.99.1) Will not make the deadline.

Thanks for the heads-up Tim -

I expect that you're running these with the -smp flag, pure and simple.
Of course it is supposed to default to 4 processors but what if it missed that call?
Next time you get one, perhaps you could try stopping it and starting it with the -smp 4 flag to see if that does anything different?

Hmm,

[05:19:20] - Calling './mpiexec -np 4 -host 127.0.0.1 ./FahCore_a2.exe -dir work/ -suffix 00 -priority 96 -checkpoint 15 -verbose -lifeline 21604 -version 624'

I cannot duplicate this behavior on the single C2D that is running Version 2.08.
Staying with 2.07 on the remaining C2D's until we determine what is going on.

More info would be available in the console vs. FAHlog.txt. Have you looked for anomalies there, BW?

I just wanted to make sure that this WU was listed as one of the bad ones. As you may have noticed I have been recently harping quite a bit about these one core SMP WUs. I wanted to make sure it got listed as bad so no one else would get this wu assigned to them.

Yeah I know BW, it's a very good thing as well and I would actually expect more reports from more people about this ( I can't imagine people would miss their installs running on one core only! ) but it's not been the storm I was abit afraid for.
