Dear all,
I am new on linux and amber. I compiled amber9 with ifort_ia32, openmpi. I
have successfully run sander.MPI run on single PC with "mpirun -np 2 ".
While I got some problem on remote node. Can anybody give me some advice ?

The error message is :

mpirun -np 2 --host wolf45,wolf46 /usr/local/amber9/exe/sander.MPI -O -i
test_min.in -o test_min.out -c test.inpcrd -p test.prmtop -r test_min.rst
