For details, you could try our book "Past, Present, Parallel: A Survey of Available Parallel Computing Systems", from Springer-Verlag, ISBN 3-540-19664-1 (in Europe; US number is different). The AP-1000 has torus topology, custom chips to do message routing (with wormholing and structured buffers), and lots of extra hardware for global synchronisation, plus all the advantages of off-the-shelf microprocessors. If Fujitsu decided to take it to market, it would be hard to beat.
