Hey guys, I'm trying to use mpi4py on my mac but I'm running into some problems. I'm just trying to get it up and running by running a simple helloworld program that runs on different processors.
When I run the command 'mpiexec -n 2 python helloworld.py' I'm getting a very long error message that starts out like:
A requested component was not found, or was unable to be opened. This means that this component is either not installed or is unable to be used on your system (e.g., sometimes this means that shared libraries that the component requires are unable to be found/loaded). Note that Open MPI stopped checking at the first component that it did not find.
If you guys would like to see the rest I could cut and paste it, but it is very long and I was going to see if anyone had an answer first.
If this is relevant typing 'which mpiexec' returns /usr/bin/mpiexec
a otool -L on MPI.so returns
/opt/local/lib/libmpi.1.dylib (compatibility version 2.0.0, current version 2.2.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.2.11)
I used sudo port install py27-mpi4py to set it up.
Thanks for your time guys!
