[mpich-discuss] job in node

[Ranjit Thapa]

Dear Balaji


Thanks for suggesting me, I have done the following step
# cd /etc
#nano exports
/usr 10.1.1.1/25.0.0.0 (rw,no_root_squash)
#ssh node01
# mount -t nfs ranjit:/usr /usr
#exit
# cd /home/mpich2-1.3.1
# mpiexec -hosts ranjit,node01 -n 40 ./examples/cpi

Its work

Now, the program run in both computer- ranjit and node01

Thanks a lot for suggesting me
