"""BOLT targets a high-performing OpenMP implementation,
especially specialized for fine-grain parallelism. Unlike other
OpenMP implementations, BOLT utilizes a lightweight threading
model for its underlying threading mechanism. It currently adopts
Argobots, a new holistic, low-level threading and tasking runtime,
in order to overcome shortcomings of conventional OS-level
threads. The current BOLT implementation is based on the OpenMP
runtime in LLVM, and thus it can be used with LLVM/Clang, Intel
OpenMP compiler, and GCC."""
