OpenMP: parallel programming API for shared memory multiprocessors and on-chip multiprocessors

The OpenMP application programming interface is an emerging standard for parallel programming on shared-memory multiprocessors. Recently, OpenMP is attracting widespread interest because of its easy-to-use portable parallel programming model. In this paper, we describe a brief introduction of OpenMP API and its parallel programming. We present our Omni OpenMP complier and performance of some applications on a shared memory multiprocessor. In the end, a role of OpenMP for modern on-chip multiprocessors is discussed.
