Title
Performance tuning of SCC-MPICH by means of the proposed MPI-3.0 tool interface
Abstract
The Single-Chip Cloud Computer (SCC) experimental processor is a 48-core concept vehicle created by Intel Labs as a platform for many-core software research. Intel provides a customized programming library for the SCC, called RCCE, that allows for fast message-passing between the cores. For that purpose, RCCE offers an application programming interface (API) with a semantics that is derived from the well-established MPI standard. However, while the MPI standard offers a very broad range of functions, the RCCE API is consciously kept small and far from implementing all the features of the MPI standard. For this reason, we have implemented an SCC-customized MPI library, called SCC-MPICH, which in turn is based upon an extension to the SCC-native RCCE communication library. In this contribution, we will present SCC-MPICH and we will show how performance analysis as well as performance tuning for this library can be conducted by means of a prototype of the proposed MPI-3.0 tool information interface.
