Piyush, Jee, and Rich are in Portland representing the lab at the SIAM Parallel Processing ’14 meeting. If you are also there, please drop by our various events! List below; resources (papers, slides) are here: [link].


We’re in Seattle this week attending the US DOE Workshop on Modeling and Simulation of Exascale Systems and Applications — “ModSim’13” [www]. A copy of Rich’s talk and pointers to supplemental materials is available here: hpcgarage.org/modsim13

DOE ExaMath’13

Rich is at the American Geophysical Union this week for a US Department of Energy workshop on “Exascale Mathematics.” You can read his position paper and talk materials [here].

See us at IPDPS’13!

Jee and Kent are speaking on Wednesday, May 22 at IPDPS’13. If you are attending, be sure to check out their talks!

  • Jee Choi et al. “A roofline model of energy.” Session 14, 10am-noon.
  • Kenneth Czechowski and R. Vuduc. “A theoretical framework for algorithm-architecture co-design.” Session 17, 1:30-3:30pm.

Both sessions are in the William Dawes Room at the Hyatt Regency Cambridge. Hope to see you there!

Rich gave a keynote at the 3rd International Workshop on Accelerators and Hybrid Exascale Systems (AsHES) earlier this week. A copy of his slides is available here: hpcgarage.org/ashes2013

Kent and Jee will each present a paper at IPDPS’13, to be held in Boston in May. Kent’s paper is about a unique take on high-level algorithm-architecture co-design; Jee’s paper is about his “roofline” energy model. If you plan to attend, be sure to see their talks! We’ve also posted preprints under Papers.

SIAM CSE’13 talks

Aparna and Jee are at SIAM CSE 2013 in Boston this week, giving talks the fast multipole method and the energy roofline, respectively. (UPDATE: Click on the title for Jee’s talk to access the PDF slides.)

VECPAR’12 + K Supercomputer

Rich has the pleasure of being at the 10th International Meeting on High-Performance Computing for Computational Science (VECPAR), held this year at RIKEN AICS research facility in Kōbe (神戸市), Japan. RIKEN is home of the amazing K Supercomputer, shown here (only partly obstructed by Rich’s head, which he wishes had as much computing power).

Rich is especially grateful to the VECPAR organizers and other hosts (here, here, here, and here, among others) for the chance to speak, to see the K Computer, and to sample Kobe beef (yes, it’s that good!). For those interested in the talk, here is a link to Rich’s slides: [PDF].

Kent on exascale @ ICS’12

Kent is in Venice, Italy this week presenting our 3D FFT exascale projection paper at ICS’12 (Session 6).

  • K. Czechowski, C. McClanahan, C. Battaglino, K. Iyer, P.-K. Yeung, R. Vuduc. “On the communication complexity of the 3D FFT and its implications for exascale.” In Proc. ACM Int’l. Conf. Supercomputing (ICS), San Servolo Island, Venice, Italy, June 2012. doi:10.1145/2304576.2304604 [PDF Preprint | PDF slides]

UPDATE: Kent is joined by fellow Georgia Tech HPC students, Rob McColl and Oded Green, who are presenting their paper on a new parallel algorithm for merging on GPUs [doi:10.1145/2304576.2304621].

UPDATE 2: PDF slides are available (see reference above).

ISC’12 + EIHECS’12

Rich is in Germany this week giving invited talks at ISC’12 (Hamburg) and EIHECS’12 (Erlangen) on our theoretical co-design work. The big news at the meeting in Hamburg is the latest Top500 list, which IBM’s Blue Gene/Q machine dominates this year. However, Germany’s SuperMUC system is also making a big splash. The meeting in Erlangen is a cozy local affair, and a great opportunity to meet members of the top international groups in computational science and performance engineering. Many thanks to the hosts at both events!

Aparna, Jee, and Rich are having East-meets-West moments in Shànghǎi (上海) this week for the IEEE Parallel and Distributed Processing Symposium (IPDPS). Aparna and Jee are part of the PhD Forum, and Rich is giving a talk at EduPar-12 and serving as a panelist on the topic of exascale algorithms [IPDPS program].
