My project for Professor Rich Vuduc's Fall 2009 CSE6230, libtorque is a multithreaded event library for UNIX targeted towards manycore NUMA machines. Previous, non-threaded event libraries include libevent, libev and liboop. My project proposal suggests motivation for libtorque: I believe it necessary to take scheduling and memory-placement decisions into account to most optimally handle events, especially on manycore machines and especially to handle unexpected traffic sets (denial of service attacks, oversubscribed pipes, mixed-latency connections, etc).
