New PDF release: High Performance Computing: Programming and Applications

By John Levesque,Gene Wagenbreth

High functionality Computing: Programming and Applications offers innovations that deal with new functionality matters within the programming of excessive functionality computing (HPC) functions. Omitting tedious information, the ebook discusses structure ideas and programming suggestions which are the main pertinent to software builders for reaching excessive functionality. although the textual content concentrates on C and Fortran, the suggestions defined might be utilized to different languages, akin to C++ and Java.

Drawing on their event with chips from AMD and structures, interconnects, and software program from Cray Inc., the authors discover the issues that create bottlenecks achieve stable functionality. They disguise concepts that pertain to every of the 3 degrees of parallelism:

  • Message passing among the nodes

  • Shared reminiscence parallelism at the nodes or the a number of guide, a number of facts (MIMD) devices at the accelerator

  • Vectorization at the internal point

After discussing architectural and software program demanding situations, the booklet outlines a technique for porting and optimizing an present software to a wide hugely parallel processor (MPP) approach. With a glance towards the longer term, it additionally introduces using common function pictures processing devices (GPGPUs) for engaging in HPC computations. A spouse web site at comprises all of the examples from the booklet, in addition to up-to-date timing effects at the most up-to-date published processors.
