I installed mpich2-1.0.5p4 on two machines and tried the example cpi.
the two machines are machine1 and machine2.
I can run ssh/rsh without password on both machines.
when I only use one machine for computation, it returned good result.
when I use two machines,
my mpd.hosts is:
I ran mpdboot -n 2 -f mpd.hosts
I ran mpdtrace, the output is :
when I ran mpiexec -n 5 examples/cpi:
the output is
Process 0 of 5 is on machine1
Process 2 of 5 is on machine2
Process 4 of 5 is on machine1
Process 3 of 5 is on machine2
Process 1 of 5 is on machine2
then the program stop there and no output then.
Can anyone help?
