Dear Sir/Madam
Greetings of the day !!
I have installed the MPICH3 on RHEL5 with the steps give in the installation manual
inside the tar file of Mpich3 .
I am using a cluster of 3 systems with all the settings done as suggested by the manual ,
and successfully able to run the example given inside the package i.e. Pi value calculation (cpi)
using the command
$mpiexec -n 6 -f machinefile ./cpi

Now when I am running some other process or some other examples the following error
is getting generated about which I have no clues how to get rid of the error

Here I am listing the programm and the command I am using and error generating

NANO35 if my master node

[user@NANO35 test]$ mpiexec -n 6 -f /home/user/machinefile ./mpi_hello
[mpiexec@NANO35] control_cb (pm/pmiserv/pmiserv_cb.c:200): assert (!closed) failed
[mpiexec@NANO35] HYDT_dmxu_poll_wait_for_event (tools/demux/demux_poll.c:76): callback returned error status
[mpiexec@NANO35] HYD_pmci_wait_for_completion (pm/pmiserv/pmiserv_pmci.c:198): error waiting for event
[mpiexec@NANO35] main (ui/mpich/mpiexec.c:344): process manager error waiting for completion

Machinefile looks like
NANO35:2
NANO36:2
NANO37:2
NANO38:2
