SPELL: Automatic Parallelizing Compiler with Hybrid Optimizations


SPELL is an automatic parallelizing compiler that aims to combine the strength of static compiler analysis and dynamic runtime optimizations.

SPELL for C/C++/Fortran (SPELL-native)

Currently, SPELL-native can automatically parallelize important loops in the libquantum, bwaves, cactusADM, leslie3d, GemsFDTD and lbm benchmarks of SPEC CPU2006.

SPELL-native is based on the LLVM 3.7.0 compiler framework. It uses the dragonegg GCC plugin to transform C/C++/Fortran programs into the LLVM Intermediate Representation (LLVM IR), and optimizes the transformed IR using LLVM. Then SPELL analyzes and parallelizes the optimized IR, and finally uses LLVM to generate the object code. We also implement a runtime library for the parallelized programs.

SPELL for .NET (SPELL-CIL)

SPELL-CIL can optimize/parallelize programs written in any programming languages targeting the .NET Common Intermediate Language (CIL), such as C#, F# and VB.NET. It employs a selective ahead-of-time (AOT) compilation approach for optimization/parallelization, which generates a native version for each function it can optimize and rewrite the CIL function to P/Invoke the native version.
