Can MATLAB Parallel Server take advantage of low latency network fabric like InfiniBand via a custom MPI?

How can I leverage a high throughput and low latency network fabric like InfiniBand with MATLAB Parallel Server on my cluster which is running a 3rd party scheduler?

It is possible to implement a 3rd party MPI like IntelMPI with MATLAB Parallel Server so that it can leverage the advanced fabric. See https://www.mathworks.com/help/releases/R2021b/matlab-parallel-server/use-different-mpi-builds-on-unix-systems.html

MPI communications like those used by distributed arrays or spmd will be able to leverage any advanced fabrics supported by the custom MPI library. The default MPI library shipped with MATLAB Parallel Server and Parallel Computing Toolbox will only use Ethernet connections.
