A few weeks ago we took a look at the new MCAPI standard that provides low-level, low-overhead message-passing capabilities for multicore and tightly-coupled multi-processor systems. But of course, standards are no good unless someone implements them, so here we take a look at the first commercially-available implementation of the MCAPI standard, built by Polycore. As MCAPI committee chair, Polycore’s Sven Brehmer has been well-positioned and motivated to bring to market a realization of the standards work.
