This tutorial covers how to write a parallel program to calculate π using the Monte Carlo method with MPI and OpenMP.
####Compiling and Running Before you start, you will need to edit the submit scripts (submit.pbs and mpisubmit.pbs) and the Makefile and replace with the correct project ID. Once done, you need to load the PGI programming environment
module load PrgEnv-pgi
To compile and submit the serial version, you need to run: make serial
- For the MPI_Reduce verion:
make mpi - For the MPI Send/Recv verion:
make mpisr - For the OpenMP version:
make omp - For the hybrid OpenMP/MPI version:
make mpiomp
The output should look something like:
Wed Sep 18 11:02:27 EDT 2013

Application 3587838 resources: utime ~0s, stime ~0s, Rss ~3444, inblocks ~4534, outblocks ~11970
