Wow. Thank you for the fast replies. You guys hardly sleep.
PROBLEM SOLVED. It works now.
Nicolás/ No. that can't be. It is my personal computer and I haven't
installed MPICH so far.
Jeff/ I saw that FAQ but didn't try --with-pm=hydra.
I first didn't configure MPICH with any process manager since hydra is set
to default according to the installation guide. I reconfigured
"--with-pm=hydra" and reinstalled. Now it is working.
Once again, thank you for your interest and help.
