NOELLE Offers Empowering LLVM Extensions

NOELLE provides abstractions to accelerate the implementation of advanced code analyses and transformations.
This software is developed for the parallelization, MARC, compiling for sub-cycle microarchitecture activities, and power of modern compilers research directions.

• NOELLE
  Beside being used for accelerating research, NOELLE is also used in the ATC class.

• NOELLE Gym: where NOELLE-based tools exercise
  Would you like to quickly test the impact of your code analysis and/or transformation built upon NOELLE?
  NOELLE Gym is designed to help you quickly test your work.
  
• Framework to compile benchmarks into a single bitcode file
  NOELLE requires a single bitcode file that includes the whole program.
  This is not typically obtained by using well-established benchmark suites like SPEC CPU2017, PARSEC, or MiBench.
  So, we developed scripts and patches and we organized them into a framework to compile benchmarks of well-established benchmark suites into a single bitcode file.
  

Parallelizing compilers

This software is developed for the parallelization research direction.

• The HeartBeat Compiler (HBC)
  The first compiler that transforms loop-based nested parallelism into binaries that benefit from heartbeat scheduling.
  
• GINO
  This software is developed for the parallelization research direction.
  
• SCAF
  An innovative design to combine alias analyses and (optionally) speculation.
  
• Collaborative Parallelization Framework (CPF)
  An innovative design to combine code transformations and parallelization to extract threads automatically.
  
• PROMPT: A Fast and Extensible Memory Profiling Framework
  A profiling framework you can use to quickly build your specific memory profiler.
  

Memory-Centric Compilers

This software is developed for the memory-centric compilers research direction.

• MemOIR
  The first compiler's Intermediate Representation (IR) with irregular data collections in Static Single Assignment (SSA) form. This enables a new data-centric family of optimizations that compilers can now do.
  

MARC: Mining Advantages in non-deteRministic Code

This software is developed for the MARC research direction.

• CARMOT
  

Runtimes

This software is developed for the parallelization, and MARC research directions.

• VIRGIL: Very sImple thRead pool desiGned with the easy Integration goaL in mind
  This is a header-only C++ library that implements a simple thread pool using the modern C++ language. The design of VIRGIL aims for an easy integration with other C++ code.
  

LLVM related software

Next there is a set of software packages I built to help LLVM development.

• Downloading, installing, and compiling LLVM .
  This software is used in almost all research directions our group follows as well as in my Code Analysis and Transformation class.
  
• Template for LLVM middle-end passes .
  This software is used in almost all research directions our group follows as well as in my Code Analysis and Transformation class.
  

My development environment

Next there is the software/configurations I use for my development environment. I hope you will find them as useful as I do.

• VIM configuration
  This is the VIM configuration I use in a Linux environment.
  

• ZSHRC configuration
  This is the ZSHRC configuration I use in a MacOS environment.
