GPU Mathy

This repository consists of codes for the Mathy Compiler. The Demo for this project is here

The Mathy compiler generates ready-to-run cuda code for commonly used mathematical expressions like forall, summation, product etc.

The project was written in C++ using Flex and Bison.

Installing Dependencies

• g++
  sudo apt install g++
• flex
  sudo apt install flex
• bison
  sudo apt install bison

Compiling Project

Run make in the src directory to generate the executable a.out This will generate some intermediate files also.

Converting Mathy to Cuda

If the Mathy code is present in input.txt, running ./a.out input.txt output.cu will create a file output.cu which will contain the equivalent Cuda code. The program assumes that all arrays are of type float.

Run make clean to remove the executable and intermediate files.

Benchmarks

Run python3 benchmark.py to generate the cuda files for mathy text files present in benchmark/input and write the outputs to benchmark/output. The benchmarks have been implemented based on PolyBench benchmarks. The results of the output code against the benchmark code have been agglomerated in this Report.

Please refer to the wiki for the Grammar and features of the Mathy language.
