SCHEDULE: NOV 10-16, 2012
When viewing the Technical Program schedule, on the far righthand side is a column labeled "PLANNER." Use this planner to build your own schedule. Once you select an event and want to add it to your personal schedule, just click on the calendar icon of your choice (outlook calendar, ical calendar or google calendar) and that event will be stored there. As you select events in this manner, you will have your own schedule to guide you through the week.
Compass - A Scalable Simulator for an Architecture for Cognitive Computing
SESSION: Optimizing Application Performance
EVENT TYPE: Papers, Best Paper Finalists
TIME: 1:30PM - 2:00PM
SESSION CHAIR: Martin Schulz
AUTHOR(S):Robert Preissl, Theodore M. Wong, Pallab Datta, Raghav Singh, Steven Esser, William Risk, Horst Simon, Myron Flickner, Dharmendra Modha
ROOM:355-EF
ABSTRACT:
Inspired by the function, power, and volume of the organic brain, we are developing TrueNorth, a novel modular, non-von Neumann, ultra-low power, compact architecture. TrueNorth consists of a scalable network of neurosynaptic cores, with each core containing neurons, dendrites, synapses, and axons. To set sail for TrueNorth, we have developed Compass, a multithreaded, massively parallel functional simulator and a parallel compiler that maps a network of long-distance pathways in the Macaque monkey brain to TrueNorth. We demonstrate near-perfect weak scaling on a 16 rack IBM Blue Gene/Q (262144 CPUs, 256 TB memory), achieving an unprecedented scale of 256 million neurosynaptic cores containing 65 billion neurons and 16 trillion synapses running only 388× slower than real-time with an average spiking rate of 8.1 Hz. By using emerging PGAS communication primitives, we also demonstrate 2× better real-time performance over MPI primitives on a 4 rack Blue Gene/P (16384 CPUs, 16 TB memory).
