SUMMARY:Low Power Photonic Networks for Shared Memory Computers - Philip W
 atts ( University of Cambridge)
DTSTART:20110225T160000Z
DTEND:20110225T170000Z
UID:TALK29982@talks.cam.ac.uk
CONTACT:Prof Simon Moore
DESCRIPTION:I will start with a practice run of my presentation for the Op
 tical Fiber Communications (OFC 2011) Conference\, investigating the condi
 tions under which adding a photonic circuit switched network to an on-chip
  or chip-to-chip network can reduce power consumption.  This is based on 
 analysis of memory traces from a 32-core shared memory system running the 
 PARSEC benchmark suite.  I will also discuss recent work on building Syst
 emVerilog models of photonic switches and time-slotted network control cir
 cuits\, demonstrating an order of magnitude reduction in power consumption
  compared with an electronic mesh network.
