The lowest latency Infiniband systems already use HTX:

Voilà, what was once a cluster becomes a NUMA SMP by cross-box Hypertransport! ============================================================ FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College lectures, archives, unsubscribe, maps at http://www.friam.org
