ABSTRACT

The IBM Blue Gene/P (BG/P) system is a massively parallel supercomputer succeeding BG/L, and it is based on orders of magnitude in system size and significant power consumption efficiency. BG/P comes with many enhancements to the machine design and new architectural features at the hardware and software levels. In this work, we demonstrate techniques to leverage the architectural features of BG/P to deliver high performance MPI collective communication primitives.
