Hello, I am new to openmpi, but would like to use it for ORCA calculations, and plan to run codes on the 10 processors of my macbook pro. I installed this manually and also through homebrew with similar results. I am able to compile codes with mpicc and run them as native codes, but everything that I attempt with mpirun, mpiexec just freezes. I can end the program by typing 'control C' twice, but it continues to run in the background and requires me to 'kill <pid>'. even as simple as 'mpirun uname' freezes
I have tried one installation by: 'arch -arm64 brew install openmpi ' and a second by downloading the source file, './configure --prefix=/usr/local', 'make all', make install the commands: 'which mpicc', 'which 'mpirun', etc are able to find them on the path... it just hangs. Can anyone suggest how to fix the problem of the program hanging? Thanks! Scott
