Hi,

Recently, I installed MPICH 1.2.2.1 on a Mandrake Linux 8.0 cluster, which
includes 4 nodes with dual processors on each node. I can run mpi program on
any one node, but it will stall there when I try to run on more than one
node. I can know that the program is started on the first node, but not the
other nodes. If I using

../../bin/mpirun -v -np 2 -nolocal cpi
The info is:
running /users/mpich/mpich-1.2.2.1/examples/basic/cpi on 2 LINUX ch_p4
processors
Created /users/mpich/mpich-1.2.2.1/examples/basic/PI21339

What do you think might be the problem?

Best regards!

Rongguang
