Preview releases of Argobots (1.0a1) and BOLT (1.0a1) are now available for download here: http://www.argobots.org/downloads/ http://www.bolt-omp.org/downloads/ Argobots is a lightweight low-level threading and tasking infrastructure and can be used as a low-level threading mechanism for diverse high-level programming models or domain-specific libraries. BOLT is a high-performing OpenMP implementation that utilizes Argobots as the primary threading model. With the ABI compatibility with the Intel OpenMP runtime, BOLT can be used with LLVM/Clang, Intel OpenMP compiler, or GCC with a simple LD_PRELOAD environment change (no recompilation needed).
