I encountered the same problem as Issue #1857. However, since I am new to the Einstein Toolkit, I don't quite understand the solution there. How do I change the MPI process to be 2? Do I just use '--procs=4 --num-threads=2' in the command? PS: I am trying the command of "!./simfactory/bin/sim create-run inspiral_d06_lres --parfile=par/inspiral_d06_lres.par --procs=4". This doesn't work and give the same error message as Issue #1857.
