Abstract

The Single-chip Cloud Computer (SCC), a 48 core experimental processor from Intel labs, is a platform for parallel programming research. Its hardware features and memory organization map naturally to message passing models. Standard and non-standard message passing libraries are already available for the SCC; one of the standard solutions is the RCKMPI library. RCKMPI's main features are three SCC specific MPICH2 channels. In this work, improvements to the SCCMPB channel are introduced; performance results for the new channel show better scaling with process count. The added flexibility of the new design also allows for the support of dynamic processes, a feature previously not supported in RCKMPI.
