This project is not actively worked on and is not complete. I originally wrote a compiler from scratch using flex and bison and defined my own language that was the basis for our paper Sarvavid. After getting more experience in the realm of compilers and programming languages I started porting the DSL over to use llvm instead, which this repository is the result. I did not finish porting or getting everything to work smoothly as I changed my area of research for my PhD. That being said, the idea was to have Sarvavid just be LLVM optimization passes allowing any libraries to be used and just optimizing any SarvLibrary Kernels along with normal optimizations. I still think it is a good idea, but I don't have the time currently to work on it. You may need to have git-lfs installed to pull all the files from this repo (There are some .fa and .h5 that are test files for some of the libraries). Also, in the SarvLibrary folder, in some of the libraries, you may need to compile yourself for them to work correctly. I added them to the repo in hopes that it will just work for you, but have not tested other than pulling the repo to a clean place on my machine and building.
This project uses Clang and LLVM to implement an embedded dsl, with compiler optimizations that work on libraries/kernels that are part of Sarvavid.
Tested with the following: "clang-6.0" "openmpi v 1.10.2"
Do 'which clang' and 'which clang++' for the CC and CXX paths respectively Change the paths in environment_setup.sh if necessary.
For best results, clean up previous builds: make clean
From the main folder, issue the following command: make all
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/full/path/to/llvm_sarvavid/build/SarvLibrary:/full/path/to/llvm_sarvavid/build/SarvPass
