The error was due to an incorrect par file setting. "---core= 2, thread= 1--" worked, thank you very much for the support.
Best, Karima S

Hello Karima,
summarizing the discussion in the call today:
for --cores 4 --num-threads 2 the issue is that simulation factory counts only "physical" cores while the OS reports "logical" cores including the hyperthreading which we originally chose to ignore
for the other error --cores 2 --num-threads 1 "The domain size for map 0 scaled for convergence level 0 with convergence factor 2 is not integer" would seem to be that the coarse grid spacing "dx" does not evenly divide the grid size xmax - xmin. If the grid spacing is indeed correct, as you indicated in the call, then best would be to provide the exact parameter file that you ran.
Yours, Roland
Dear Dr. Ronald and Dr. Peter, I have a 4 core laptop, and I am using 'Simfactory' command to run the
par
file. I have tested both of your suggestions. The addition of "--cores=2 --num-threads=1" gives me the attached error while the "--cores=4 --num-threads=2" option gives, "Error: Too many nodes specified: nodes=2 (maxnodes is 1)
Aborting Simfactory".
Thanks
Best,
KS

Hello there,
Here is the error attached I encountered while evolving black holes binary. The work-around I guess is to increase the number of processes
(if
I am not wrong), but I am not quite sure how to do that. I need some
help
to get around this issue.
Thanks in advance
Best regards, KS
