[Wien] Error while parallel run

[alpa dashora]

Dear Wien2k Users,

I recently installed Wien2k with openmpi on 16 processor server.
Installation was completed without any compilation error. While running the
run_lapw -p command, I received the following error:
------------------------------------------------------------------------------------------------------------------------------

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

Executable:-4
Node: arya

while attempting to start process rank 0.
-------------------------------------------------------------------------------------------------------------------------------

Kindly suggest me the solution.
mpirun is available in /opt/openmpi/1.3/bin

Thank you in advance.

Regards,
