[gmx-developers] mpi error

[Junmin Quan]

Dear All,


   When I run the CVS version of gromacs on a dual processors (dual
opteron) system, I met the following error. I compile gromacs with
--enable-mpi, I have setup lammpi, fftw for mpi.   Any suggestion is
grateful.

Best

Back Off! I just backed up ener.edr to ./#ener.edr.2#

code.  This typically indicates that the process finished in error.
If your process did not finish in error, be sure to include a "return
0" or "exit(0)" in your C code before exiting the application.
