I tried to run a hello world example of mpi code. It just hangs at
MPI_Init. My machine is installed with Ubuntu linux and I install some
package of open mpi. Compiling was okay, but running the code hangs at
MPI_Init. Is there any specific things that I should do before running
mpi code such as "mpd" setup?
I will appreciate any help.
Live, Learn, and Love!
