I have tried to use v1.1 openmpi. but the program (AMBER9) I am using can't
be compiled correctly by v1.1. So I seems that I have to keep using
openmpi-1.02.
I am new in linux, I really have no idea about debugger. Would you please
give me some advice to try in a simple way?
Thank you very much!

Ick. This isn't a helpful error message, is it? :-)
Can you try upgrading to the recently-released v1.1 and see if the error
is still occurring?
Have you tried running your application through a memory-checking debugger
such as valgrind, perchance?

Thank you very much. This problem is solved when I change the shell of
remote node to B shell. Because I set the LD_LIBRARY_PATH in .bashrc file
while the default shell was C shell.
Althoguth it works on my testing program test.x, some errors occured when
I run other programme. BTW, I tried to run this programme on single PC with
2 np successfully.
Any suggestions? Thank you
