Project: 2684 (Run 7, Clone 3, Gen 0)

DrSpalding · Post by **DrSpalding** » Wed Jun 09, 2010 4:23 pm

A Linux VM running -bigadv received the project above this morning and immediately failed with "mdrun returned 255" and corestatus = 7a (122). I don't think it is an unstable machine. Maybe the VM needs to be rebooted, but it has since started a 2681 WU w/o any issues. I understand the difference between the multi-threaded A3 core and the MPI A2 core but don't quite understand why the A3 core would be less stable for the OS vs. the more complex MPI/A2 core. I have removed FahCore_a3.exe from the machine just in case something was corrupted but I don't have much reason to believe that it was something on my end.

As an aside, I am actually kind of glad because based on the frame times on my overclocked i7 machine of 48 minutes, this stock i7 would probably not finish the WU in under the preferred deadline constraint.

Here is the log:
