MPICH2 gethostbyname failed

Question

I don\'t understand the error message. I am trying to do is to run a MPICH2 application after I installed mpich2 version 1.4 or 1.5 to /opt/mpich2 (both version fai

Answer 1

Being the question different, the answer is probably the same I gave time ago for OpenMPI: gethostname() function missing in openMPI

The MPI portable solution is to use MPI_Get_processor_name()
