I am trying to run the HPCC-1.5.0 benchmark on the cluster using the intel-2019 compilers and mpi. I was able to successfully compile the hpcc code and run it on up to 4 cores on the head node. But if I increase the number of cores, the benchmark seems to hang at the "Begin of MPIRandomAccess section" (which is the very first benchmark test). I can run the same code successfully using intel-2013 compilers and mpi. Has anyone else faced anything similar or have any pointers to what could be happening and how to fix it? Any help is greatly appreciated!
