Hello,
The service from Hpcpack (msmpi) and MS-MPI (msmpilaunchsvc) are sharing the same port and thus only one of them should be running. If you want to use MSMPI with Hpc pack please use the submission feature of hpc pack to run the jobs. You can take a look
at the reference here

The MSMPI launch Service is designed to address the need of running ms-mpi in an environment without HpcPack. If you can describe to us in more detail what you’re trying to do we can offer more specific suggestions.
Thanks
Anh
