[BProc] mpi problems

[Nasikas P. <pn...@it...>]

Hi ,

I've setup(or at least think so...) Clustermatic that uses
Bproc for process migration.The slave nodes boot without
problems and I can confirm that through bpstat.
When I try to run programs with mpirun I get some
problems....
I get the following message
" p0_4561:  p4_error: Could not gethostbyname for host n1; may be invalid
name: 61"

n1 is the name of the slave node(I use only one initially for the
configuration).I've changed the entries in the file
/usr/mpich-p4/share/machines.LINUX to include the name n1(and my
server's hostname) but nothing changed I get the same error message
again and again.

Has anyone expierienced the same problems?What might be a solution?

Thanks for your time
