Mathy Compiler

This is a compiler to generate OpenMP programs for equations involving constructs like Forall, Summation etc., frequently used in the scientific domain.

This project is written in C++ using Bison and Flex.

Feel free to make a PR or raise an issue if you find any bugs, or if you're interested in making improvements.

How to use

Compile this project:

cd source
make install

Open a file and write an equation like this:

mean = sigma(a[i]/100) where 0<=i<=100

Or if you like Unicode characters,

mean = Σ(a[i]/100) | 0<=i<=100

The above equation, when compiled using the above mentioned compiler, will output an OpenMP program that will

• Declare an array a of 101 floats
• Calculate the mean of those 101 elements and store it in the variable mean
• Calculate the time taken to do the above work, including the time for function call

To generate OpenMP program for the equation:

./test filename [-o output_filename] [-t data type for variables]

The equations in benchmark/source are implementations of programs from PolyBench/C.

The OpenMP outputs for these equations can be found in benchmark/output.

To compile all the source files in benchmark, from the root directory, run

python3 benchmark.py

Please refer to the wiki for the Grammar, Syntax and currently supported features of the project.
