[mpich-discuss] problem with execution of examples/cpi

Mon Jun 30 12:56:55 CDT 2008

It is solved, half by you all guys and half by myself. I really needed to
add "./" but also I had some things to fix in nfs. I was sharing just the
mpich folder, not the whole environment of my tools, so it couldn't catch
the cpi file in the other computers. But thanks a lot!
