Marat recently released version 1.0 of his Yeppp! library, which includes fast portable implementations of vector elementary functions (e.g., log/exp, trigonometric functions) and polynomial evaluation. See: yeppp.info
The HPC Garage at Georgia Tech studies high-performance computing. Our work spans parallel algorithms, programming models, performance analysis, automated tuning (autotuning), and debugging. We target applications in computational science and engineering (CSE), which include computer-based simulations of natural and engineered systems and analysis of massive data sets.
