mpiexec error: gethostbyname while installing hdf5 in parallel

Hi all,

I am new user on UNIX systems and I want to install on my laptop WRF and POM in parallel. However, I have faced some problems to install and execute properly hdf5 in parallel. Thus, after I installed mpich2 on my SUSE and set the path correctly to its bin and I try to run an example I keep getting this error:

mpiexec failed: gethostbyname_ex failed for my_username

As a result, this error blocks the installation of hdf5 in parallel on my laptop, showing me the same error after I make check on terminal.

Does anyone knows or could help me to set this correctly?

Thanks in advance

Matheus
