Unable to start the parallel computing on a linux machine

Hi, I failed to start a parallel computing job on the linux machine. I attached the diagnose file here. Hope someone would give me some idea about how to fix it. Thank you.

It looks like you have an 'mpiLibConf.m' on your path that is trying to pick up Intel's MPI. This will not work with the local cluster type because it cannot be configured to use the correct mpiexec to match the MPI library. I would suggest removing the 'mpiLibConf.m' and trying again.
