First test would be can you emulate Linux on a box with multiple chips, and run the futexs through a contrived heavy load environment, with all affinity masks of participating threads bound to a single chip? So, using two chips reading with non-conflicting pieces of a single shared main memory is bad? Think of RCU, with two reader chips... RCU = Read-Copy Update Another chip is the writer; the update part in RCU. So, three chips, two readers, one writer. A simple description: http://en.wikipedia.org/wiki/Read-copy-update
