Divya:

Are you using back quote/back ticks `` instead of single quote '' before and after `which esysparticle`?

Dear Sir,

I am using single quote only sir. I could not understand the meaning of following error "mpirun was unable to launch the specified application as it could not find an executable". I could not find solution. Please give suggestion to solve this.

Thanks and Regards

Hi, Divya:

You need to use backquotes (backtick) to surround `which esysparticle` instead of single quotes as this will return the full (absolute path) of esysparticle and pass this parameter to mpirun. You might need to google some references about bash fundamentals:

http://unix.stackexchange.com/questions/27428/what-does-backquote-backtick-mean-in-bash

Before running your full command, try in your terminal:

$which esysparticle

to verify if you have installed esysparticle correctly.

Regards,

Feng
