HPC and Big Data: A “Best of Both Worlds” Approach

Mar 31, 2014 |

While they may share a number of similar, overarching challenges, data-intensive computing and high performance computing have some rather different considerations, particularly in terms of management, emphasis on performance, storage and data movement. Still, there is plenty of room for the two areas to merged, according to Indiana University’s Dr. Geoffrey Fox. Fox and his Read more…

Benchmarking MPI Communication on Phi-Based Clusters

Mar 12, 2014 |

Intel’s Many Integrated Core (MIC) architecture was designed to accommodate highly-parallel applications, a great many of which rely on the Message Passing Interface (MPI) standard. Applications deployed on Intel Xeon Phi coprocessors may use offload programming, an approach similar to the CUDA framework for general purpose GPU (GPGPU) computing, in which the CPU-based application is Read more…

SC13 Research Highlight: There Goes the Performance Neighborhood…

Nov 16, 2013 |

Message passing can take up a significant fraction of the run time for massively parallel science simulation codes. Consistently high message passing rates are required for these codes to deliver good performance. At Supercomputing 2013 (SC13), our research team from Lawrence Livermore (LLNL) will present the results of our study that show that run-to-run variability Read more…
