Tiny Manna

A miniaturized Sandpile Model was used as a subject of experiments on optimization, including compilation, HPC, SIMD, and MIMD improvements.

This is currently a work in progress for the parallel computing elective subject by @inescipullo and @ZimmSebas.

The Original folder only has experiments with flags and a couple of improvements over the code.

The SIMD folder has an intrinsic approach using 256 bits vector instructions (a pack of 16 shorts).

The MIMD folder has a combination of SIMD with intrinsics and OpenMP parallelization.

How to run

For a naive run, you can use:

make
./tiny_manna

But for more efficiency, you can specify compilator and flags, something like:

make CXX=g++ CXXFLAGS="-std=c++17 -O3 -march=native -mavx2"
./tiny_manna

See the Makefile for more options
