So I installed Channelflow 2.0 on my Manjaro Linux machine, with -DUSEMPI=on. I have openMPI on this machine.
Channelflow installed successfully and passed all make tests, but when I attempt to set -np0 and -np1 to anything other than 1 and 1, I get
CfMPI: number of MPI-processes < nproc0*nproc1
Which seems to indicate to me that I need to do something else in order to enable the usage of multiple processes. Can someone help with this?
