2D Heat Equation

Simple 2D Heat equation implementation using different programming methods. Below are instructions for fortran compilation.

General Instructions

• Go into the code directory
• Edit the input.dat file
• The values in input.dat correspond to: grid size, sigma, nu, domain length, time iterations
• Read below for specific compilation instructions

For fortran/serial

• You need gfortran to compile the code

For fortran/cuda_cuf and fortran/cuda_kernel

• You need nvfortran to compile code

For fortran/mpi+cuda

• You need nvfortran and mpif90 from Openmpi
• Please check the makefile in this directory for specific compilation options which include both CUDA Aware and CUDA Not aware MPI implementations

For fortran/hip

• HIP implementation works for both CUDA and AMD GPUs
• For installing hip, I recommend using spack and installing the following packages:

spack install hip; spack install hipfort

• For more instructions to change the GPU platforms, please check this repo

Note: I am almost sure that the implementations should work. If in case you find any bugs, please send me a pull request.
