Automatic Task-Based Parallelization using Source to Source Transformations

Participants : Bérenger Bramas, Garip Kusolgu.

Bérenger Bramas and Garip Kusolgu worked on a new approach to parallelize automatically any application written in an object-oriented language. The main idea is to parallelize a code as an HPC expert would do it using the task-based method. With this aim, they created a new source-to-source compiler on top of CLang-LLVM called APAC. APAC is able to insert tasks in a source-code by evaluating data accesses and thus generating the correct dependencies. An important and challenging part of the work consists in managing the granularity, which requires to work both statically on the code but also by delegating decisions at runtime.
