hi,all:
I am a first user of openmpi, I have used mpich before.I found there
are many differenties between them.So I am confused.
I build openmpi on a ps3 using default option,that is
$ ./configure --prefiex=
$ make all install
I modify my .bash_profile file

If you have root privileges this seems to be a another good approach.
I don't, but will explain the issue to sysadmin. Thanks

Setting F77=gfortran did the trick.

Hi,
Administrators changed our cluster network topology, and now it has
narrowly-scoped netmasks for internal and outside part of the cluster.
Of course my soft stopped working giving an error during MPI_Init, then
I checked in the FAQ:
How does Open MPI know which TCP addresses are routable
