From 20 to 24 Februari, 2012, the Centre for Plasma Astrophysics hosts the workshop “Plasma Astrophysics, acquired knowledge and future perspectives“. The weeklong workshop will serve to survey acquired knowledge, identify modern challenges barely researched by theoretical approaches, and stimulate new collaborations on both historic as well as contemporary open questions in plasma astrophysics. Why [...]
On Thursday February 16 2012, Steve Pawlowski (Intel Senior Fellow & CTO Datacenter and Connected Systems Group) will give a seminar on Overcoming the Barriers to Exascale through Innovation at 16:00 in Auditorium 200K 00.06 of the KU Leuven. The event is free of charge, but you have to confirm your attendence by sending mail [...]
Recent analyses demonstrate that HPC systems experience simultaneous (often correlated) failures. In addition, statistical analyses suggest that silent soft errors can not be ignored anymore, because the increase of components, memory size and data paths (including networks) make the probability of silent data corruption (SDC) non-negligible. The Fault-Tolerance for HPC at Extreme Scale (FTXS 2012) [...]
From February 15 to February 17, Dirk Roose, Pawan Kumar, Albert-Jan Yzelman, Arnaud Beck, Trevor Carlson, Wim Vanroose and Pieter Ghysels will be attending the SIAM Conference on Parallel Processing for Scientific Computing (PP12) in Savannah, Georgia. There will be a minisymposium organized by members of the lab on “Hardware/Software Co-design for High-performance Coupled Physics [...]
At the SC11 supercomputing conference, the Intel Exascience Lab released Sniper, our fast and accurate multi-core simulator, as open source. It is available for download at http://snipersim.org and can be used freely for academic research. Sniper is a next generation parallel, high-speed and accurate x86-64 simulator. This multi-core simulator is based on the interval core [...]
We are happy to announce that the paper Improving the arithmetic intensity of multigrid with the help of polynomial smoothers (by Pieter Ghysels, Przemysław Kłosiewicz and Wim Vanroose) was accepted at the 15th Copper Mountain Conference on Multigrid Methods. The full paper can be found in our publications section, but here is its abstract: The [...]
Pascal Costanza, a member of the ExaScience Lab, presented our work in progress on resilient work stealing at the Intel Software Professionals Conference 2011, an Intel-internal event that took place in Shannon, Ireland on October 19, 2011.
Five members of the lab, Karl Meerbergen, Dirk Roose, Wim Vanroose, Przemyslaw Klosiewicz and Pieter Ghysels will be attending the Thirty-sixth Woudschoten Conference, an event organized by the Dutch Research Community Scientific Computing. Przemyslaw Klosiewicz will be presenting a poster on “Increasing the computational intensity of stencil calculations: memory bandwidth vs CPU speed”.
In a previous newsflash we informed you that the paper “Using Cycle Stacks to Understand Scaling Bottlenecks in Multi-Threaded Workloads” (Wim Heirman, Trevor Carlson, Shuai Che, Kevin Skadron, Lieven Eeckhout ) was accepted at the 2011 IEEE International Symposium on Workload Characterization. You can now find this paper in our publication section. Happy reading!
