Clusters based on commodity components continue to be very popular for high-performance computing (HPC). These clusters must be careful to balance both computational as well as I/O requirements of applications. This I/O requirement is generally fulfilled by a high-speed interconnect such as InfiniBand. The balance of computational and I/O performance is often changing, with the latest change being...
The increasing demand for computational cycles is being met by the use of multi-core processors. Having large number of cores per node necessitates multi-core aware designs to extract the best performance. The Message Passing Interface (MPI) is the dominant parallel programming model on modern high performance computing clusters. The MPI collective operations take a significant portion of the communication...
