Hi Ian,
Thanks for replying. This didn't work for me, but I understand your logic. Is there a way that I can determine how many threads per process my simfactory is configured for? That way I should be able to specify the exact # of procs right?
Thanks!

Hello,
When running the default qc0 simulation, I get an error (see attached). This was run using the following command in the windows linux subshell:
./simfactory/bin/sim create-run qc05 \ --parfile=par/qc0-mclachlan.par
The simulation runs for about an hour before aborting; I get partial output files but only with two data points. Can you please advise on how to address this issue?
Hi,
We should have a FAQ... You need to run on at least two processes, due to internal limitations in the code. So add
--procs 2
to your create-run command line.
[I don't know exactly how your machine is configured in simfactory; if it is configured to use more than one thread per process, then you need to use enough "--procs" (which really means "threads") that at least two MPI processes are used.]
