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? ------------------------------ *From:* users-boun...@open-mpi.org [mailto:users-boun...@open-mpi.org] *On Behalf Of *Chengwen Chen *Sent:* Wednesday, July 05, 2006 3:32 AM *To:* Open MPI Users *Subject:* Re: [OMPI users] error in running openmpi on remote node 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?
