What is Galois?
Galois is a system that automatically executes "Galoized" serial C++ or Java code in parallel on shared-memory machines. It works by exploiting amorphous data-parallelism, which is present even in irregular codes that are organized around pointer-based data structures such as graphs and trees. The Galois system includes the Lonestar benchmark suite and the ParaMeter profiler.
A good introductory paper to Galois is The Tao of Parallelism in Algorithms.
Multicore processors are becoming increasingly the norm. As a result, we need to find ways to make it easier to write parallel programs. Galois allows the programmer to write serial C++ or Java code while still getting the performance of parallel execution. All the programmer has to do is use Galois-provided data structures, which are necessary for correct concurrent execution, and annotate which loops should be run in parallel. The Galois system then speculatively extracts as much parallelism as it can. The current release includes a dozen sample benchmarks applications from a broad range of domains that are written using the Galois extensions and classes.
The latest release along with instructions on how to install the Galois system and run a sample benchmark application can be found here.
