The BlueGene/L supercomputer uses system-on-a-chip integration and a highly scalable 65,536-node cellular architecture to deliver 360 Teraflops of
peak computing power. Efficient operation of the machine requires a
fast, scalable and standards compliant MPI library. Researchers at IBM
and Argonne National Laboratory are porting the MPICH2 library to
BlueGene/L. We present the current state of the project and discuss the
features critical to achieving performance and scalability.
