<p>You probably have an incorrect MPIRUN environmental parameter. You have not provided enough information, and need to do a bit more analysis yourself.</p>

Dear Wien2k Users,<br>
<br>
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:<br>
------------------------------------------------------------------------------------------------------------------------------<br>
<br>
mpirun was unable to launch the specified application as it could not find an executable:<br>
<br>
Executable:-4<br>
Node: arya<br>
<br>
while attempting to start process rank 0.<br>
-------------------------------------------------------------------------------------------------------------------------------<br>
<br>
Kindly suggest me the solution.<br>
mpirun is available in /opt/openmpi/1.3/bin<br>
<br>
Thank you in advance.<br>
<br>
Regards,<br>
<br>
