There's not enough information here to help. The error
output
*seems* to indicate that you ran into some kind of file
writing
problem that was unrelated to MPI, and I'm guessing that
things went
downhill from there. Specifically, "File writing
problem" is not a
string that appears in the LAM/MPI source code. You might
look for
it in your code (or any other libraries that you use) and a)
see why
it can happen, and b) when it does happen, what happens to
your
program after that? I'm guessing that it exits with a
non-zero
status to indicate that it completed in error. If this is
the case,
LAM is simply reporting this to you.
