Dear all,

I have prepared a 10 node ubuntu based cluster, following the guidelines
described in "

I have followed each and everthing as mentioned in the above documents.
everything is Ok, now I try try to check the cluster by executing the

mpiuser at master:~$ mpiexec -f hosts -n 3 /home/mpiuser/bin/cpi

then this return with the error.

mpiexec was unable to launch the specified application as it could not find
an executable:

Executable: -f
Node: master

I could not solve this. I don't know why this happening. However,
executable "cpi" is in      /home/mpiuser/bin.

I request you all to kindly help me to overcome this problem.
thanking in advance.

yours sincerely

Haider Abbas
