Dear Ross Walker and netters,

I can compile sander with parallel on Linux cluster as Ross's suggestion.
However, I have some problem.

My Linux cluster contains 12 boxes and 2 processors in each box (total 24
processors). When I submitted my job on box2 (or other boxes which are not
box1) with command

% mpirun -np 2 $AMBERHOME/exe/sander -O -i input -o output -c ...

I want to run 2 process on the same box (box2).I found that 1 process was
running on box2 and another process was running on box1. I don't know why?
Could you please give my the suggestion?

Sincerely Yours,
