The workshop theme is “Trends in Computational Science and Engineering: Foundations of Modeling and Simulation” and will take place March 14 to March 16, 2011. The conference program consists of two building blocks: contributed talks and an extensive poster session for new and upcoming Ph.D. students. Poster submissions are cordially invited; registration closes February 12, 2011. More information is available at and UbiCast Partner to Offer GPU-Accelerated Deep Audio Search

December 6th, 2010

From a press release:, the speech indexing company, announced a partnership with UbiCast, a leading webcast equipment and hosting provider. Through the partnership, UbiCast will become the first company to offer deep audio search as a standard, cost-effective feature to customers.

Florent Thiery, CTO of UbiCast, said: “UbiCast customers produce large amounts of high-value content, but finding and retrieving archived information has been a challenge. Until now, rich spoken content has not been searchable on a broad scale because it was simply too expensive to process. The new technology, which is accelerated by GPUs, is making ubiquitous processing cost-justifiable for the first time ever.” Read the rest of this entry »

GPU Computing Session at the Spring Conference of the German Physical Society in Dresden (Germany), March 13-18, 2011

November 27th, 2010

Next year’s spring meeting of the German Physical Society (DPG) in Dresden, Germany, includes a focus session “GPU Computing”. This session is jointly organized by the divisions “Physics of Socio-Economic Systems (SOE)” and “Statistical Physics and Dynamics (DY)”. Therefore, a large audience is guaranteed. Although this is the annual meeting of the German Physical Society, it has become an international meeting where almost all of the talks are presented in English. It is a large and diverse meeting with about 7000 participants altogether. The meeting takes place from March 14-18, 2011. Abstracts for contributions are cordially invited and should be submitted online by Wednesday, Dec. 1st.

Understanding throughput-oriented architectures

November 24th, 2010


For workloads with abundant parallelism, GPUs deliver higher peak computational throughput than latency-oriented CPUs. Key insights of this article: Throughput-oriented processors tackle problems where parallelism is abundant, yielding design decisions different from more traditional latency oriented processors. Due to their design, programming throughput-oriented processors requires much more emphasis on parallelism and scalability than programming sequential processors. GPUs are the leading exemplars of modern throughput-oriented architecture, providing a ubiquitous commodity platform for exploring throughput-oriented programming.

Amazon announces GPUs for Cloud Computing

November 22nd, 2010

From a recent announcement:

We are excited to announce the immediate availability of Cluster GPU Instances for Amazon EC2, a new instance type designed to deliver the power of GPU processing in the cloud. GPUs are increasingly being used to accelerate the performance of many general purpose computing problems. However, for many organizations, GPU processing has been out of reach due to the unique infrastructural challenges and high cost of the technology. Amazon Cluster GPU Instances remove this barrier by providing developers and businesses immediate access to the highly tuned compute performance of GPUs with no upfront investment or long-term commitment.

Learn more about the new Cluster GPU instances for Amazon EC2 and their use in running HPC applications.

Also, community support is becoming available; see for instance this blog post about  SCG-Ruby on EC2 instances.
