Abstract :
The XMOS XK-XMP-64 is an experimental multi-processor board that demonstrates the scalability of the XS1 architecture; it connects 64 XCore processors, providing 512 hardware threads and 25.6 GIPS aggregate performance. This paper briefly overviews the XK-XMP-64, giving a simple example program and presenting the results of a set of experiments designed to benchmark its performance. These include message latencies and timings for barrier synchronisations and well-known static traffic permutations.
