XMP-64 performance experiments ============================== This is the source code for a set of performance experiments for the XMOS XMP-64 board, a general-purpose 64-core parallel computer. They obtained detailed measurements for barrier synchronisations and static and random traffic permutation patterns. Publised documentation of the results can be found on the XMOS website: http://www.xmos.com/published/xmp-64-performance-measurements. Compilation requires the *patched* XMOS 9.9.2 tools or greater. For more information on the XMP-64 board visit https://www.xmos.com/products/development-kits/xmp-64. The project contains three main programs: - A 'ping' programs which measures message latency between pairs of nodes - A 'barrier' program which measures the time taken for all nodes to complete a barrier synchronisation. - A 'traffic' program which measures message latency under different traffic permutations Perhaps most useful is the 'common' directory which includes more general code, including: - Timing functions written in assembly used in... - Global clock synchronisation over the hypercube. - General hypercube functions such as minimum and maximum. - A simple pipe communication structure.
