Hello all,

Recently I'm running MPICH 1.0.6(installed by FreeBSD Ports Collection) on
bother Master (Xeon 3.0G/FreeBSD amd64/named SLIM) and Slave (Celeron
700Mhz/FreeBSD i386/named big-234), all other tests finished smoothly...but
when i use mpiexec to run example/cpi on this small cluster, the output is

[horus at slim] ~> mpiexec -l -n 2 ./cpi
0: Process 0 of 2 is on slim.xxx.xx.cn
1: Process 1 of 2 is on big-234.xxx.xx.cn

and it just stopped there without any outputs. seems like no response (the
value of PI) from both SLIM and BIG
then i use Ctrl-C to finish it. After that, I tried this command: $ mpiexec
-host big-234 example/cpi on Slim, i can get this:

Process 0 of 1 is on big-234.xxx.xx.cn
pi is approximately 3.1415926544231341, Error is 0.0000000008333410
wall clock time = 0.002024

but i can use $ mpiexec -l -n 30 /bin/hostname to get it print all the
hostnames correctly.

Can anybody help me out? All helps are greatly appreciated.

CHEERS,
HORUS Lee
