DescriptionOptimizing compilers for task-level parallelism are
still in their infancy. This work explores a compiler
front end that translates OpenMP tasking semantics to
Tapir, an extension to LLVM IR that represents fork-join
parallelism. This enables analyses and optimizations
that were previously inaccessible to OpenMP codes, as
well as the ability to target additional runtimes at
code generation. Using a Cilk runtime back end, we
compare results to existing OpenMP implementations.
Initial performance results for the Barcelona OpenMP
task suite show performance improvements over existing
implementations.
