PASC’14

Rich is spending the week at ETH Zürich attending the Platform for Advanced Scientific Computing (PASC) Conference. Many thanks to two of the co-organizers, Markus Püschel and Olaf Shank, for being great hosts!

IPDPS’14

Jee and Rich are in Phoenix this week for IPDPS’14, where Jee will present his latest updates to his “energy roofline” model [Tue May 20, Session 11] :

Rich also has the pleasure of serving in a panel discussion at the High-Performance, Power-Aware Computing workshop. His position is that power-aware scheduling is really an optimal control problem. For his 1-slide summary, see: [link]

Outside our group, Georgia Tech has a very strong representation this year. Looking at the program, we count 9 papers, including two of the four “Best Papers.” Go, Buzz!

SIAM PP14

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].

Dagstuhl 13401

This week Rich has the great fortune of attending Dagstuhl Seminar 13401: Automatic Application Autotuning for HPC Architectures. He’ll be summarizing Jee’s work (with critical assists by Marat) on the energy archline model. For his slides and pointers to relevant materials, look here: [www]

ModSim’13

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

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.
