As you select events in this manner, you will have your own schedule to guide you through the week.
The Universe at Extreme Scale - Multi-Petaflop Sky Simulation on the BG/Q
SESSION: ACM Gordon Bell Prize II
EVENT TYPE: ACM Gordon Bell Finalists
TIME: 1:30PM - 2:00PM
SESSION CHAIR: David H. Bailey
AUTHOR(S):Salman Habib, Vitali Morozov, Hal Finkel, Adrian Pope, Katrin Heitmann, Kalyan Kumaran, Tom Peterka, Joseph Insley, David Daniel, Patricia Fasel, Nicholas Frontiere, Zarija Lukic
ROOM:155-E
ABSTRACT:
Remarkable observational advances have established a compelling
cross-validated model of the Universe. Yet, two key pillars of this
model -- dark matter and dark energy -- remain
mysterious. Next-generation sky surveys will map billions of galaxies
to explore the physics of the 'Dark Universe'. Science requirements
for these surveys demand simulations at extreme scales; these will be
delivered by the HACC (Hybrid/Hardware Accelerated Cosmology Code)
framework. HACC's novel algorithmic structure allows tuning across
diverse architectures, including accelerated and multi-core systems.
Here we describe our efforts on the IBM BG/Q, attaining unprecedented
performance and efficiency (2.52 PFlops, more than 50% of peak on a
prototype system, 4X expected for the final submission) at extreme
problem sizes, larger than any cosmological simulation yet performed
-- more than a trillion particles. HACC simulations at these scales
will for the first time enable tracking individual galaxies over the
entire volume of a cosmological survey.
