This directory contains a working implementation of two dimensional heat equation both in C++ and in Fortran. Code has been parallelized in a hybrid fashion with MPI and OpenMP.
- Read a short description of the theory and the numerical implementation in the code.
- Get yourself familiar with the code and basic ideas behind the parallelization.
- Build the code with the provided Makefile (by typing
make). - Try to run the code in Mahti with different parallelization options, and investigate the performance. You may try also different input parameters. There is a template batch job script job_hybrid.sh that you can use for hybrid MPI+OpenMP runs.
