[mpich-discuss] Cannot use the main node to run a process of the programme

[Waruna Ranasinghe]

Hi all,

I'm using MPICH2 in Windows.
I can run my programme without errors if I don't use the machine in which I
execute the command (Main node).

mpiexec -channel ssm -n 3 -exitcodes -machinefile "c:\Program
Files\MPICH2\bin\hosts.txt" -wdir //10.8.102.27/ClusterShared GBMTest

If I use the main node also to execute one of the 3 processes, then it gives
the error below. But it prints the output I wanted too. then it gives the
error.
I wanted to know whether this is an issue with my programme(GBMTest) or I
cant use the main node to run the process.
In the machinefile I have included three machines.
10.8.102.28
10.8.102.30
10.8.102.27 (main node)

This works fine if I remove the main node and add another node instead.

this is the error.
