Abstract
We introduce OpenMP for multicore programming through the eyes of the BSP programming model. An overview over some terminology for the programming of multicore CPUs and some syntax discussions allow us to define well-suited loops for OpenMP BSP. Following a sketch of the data transfer throughout the termination of the bulk, we abandon the academic notion of BSP and introduce shared memory data exchange via critical sections and atomics. Remarks on variable visibility policies and some scheduling options close the chapter.
