[mpich-discuss] Problem while running example program Cpi with morethan 1 task

[Thejna Tharammal]

 Hi Pavan,
This is the result of the test you suggested(1.3b,nemesis,hydra),
 second one without the env mpich_no_local,(it gives the same error for >1
tasks on one node)
-bash-3.2$ mpiexec -n 7 -env MPICH_NO_LOCAL=1 ./cpi
Process 0 of 7 is on k1
Process 1 of 7 is on k1
Process 2 of 7 is on k1
Process 3 of 7 is on k1
Process 5 of 7 is on k1
Process 6 of 7 is on k1
Process 4 of 7 is on k1
pi is approximately 3.1415926544231239, Error is 0.0000000008333307
wall clock time = 0.001221

-bash-3.2$ mpiexec -n 7 ./cpi
Process 0 of 7 is on k1
Process 1 of 7 is on k1
Process 4 of 7 is on k1
Process 5 of 7 is on k1
Process 6 of 7 is on k1
Process 3 of 7 is on k1
Process 2 of 7 is on k1
pi is approximately 3.1415926544231239, Error is 0.0000000008333307
wall clock time = 0.000221
APPLICATION TERMINATED WITH THE EXIT STRING: Terminated (signal 15)

Thanks,
Thejna
