I am trying to run a simple Geometry optimization on a 6-core machine, whenever i try to run the simulation it shows this error.

"Open MPI tried to fork a new process via the "execve" system call but

failed. Open MPI checks many things before attempting to launch a

child process, but nothing is perfect. This error may be indicative

of another problem on the target host, or even something as silly as

having specified a directory for your application. Your job will now

abort.

Local host: linux

Application name: /home/physics/Downloads/DiamondSi/diamondSi/job.sh

Error: Exec format error"

what could be reason fo this and how we are going to tackle this ?
