Realizing GPU Computation at Scale

GTC 2015

A “perfect storm” is brewing: Data volumes are increasing exponentially, mathematical models are growing ever more sophisticated and computationally intensive, but power and cooling are limiting the systems that can be deployed. These considerations are driving the use of GPUs as accelerators for computationally intense workloads. Accelerators are commonly deployed in a 1:1 configuration with conventional CPUs. Applications typically run across the two types of processors, with 95 percent of the application running on the conventional CPU and the computationally intense 5 percent running on the accelerator. However, in many applications this is still not sufficient. Many applications in financial services, the oil and gas sector, signal ... [ Read More ]

Spark, Spark, Spark Your Data

Big Data Paris Cray Blog

We recently attended Strata+Hadoop World in San Jose, where we had some very interesting conversations with attendees. It really seemed like the Hadoop audience is beginning to get comfortable with the technologies and have settled in on at least a few of the components of this dynamic and vibrant big data community. We also attended Stata+Hadoop World in New York last October, where we officially took the wraps off the Urika-XA™ extreme analytics platform. That is when I first noticed a change in the general attitudes. To give you a feel, please allow me quote from the Zaloni Blog:  “Spark, Spark, Spark, Spark! Everyone is talking about Spark, even people that you think wouldn't care about Spark are talking about it, using it, ... [ Read More ]

17 Reasons to Participate in the Cray User Group

CUG2015

Whether you are in the midst of a polar vortex or lounging on the beaches of Australia, CUG 2015 is just around the corner, April 26-30, in Chicago. We have seen a tremendous outpouring of interest in the Cray User Group over the past few years, with technical speaking slots becoming more competitive and attendance steadily on the rise. Chicago is a marvelous city with a storied past, full of exceptional cuisine, museums, sporting events and cultural venues. There’s something for everyone. The Cray User Group is focused on expanding knowledge and providing a venue for long-lasting relationships for members and sponsors alike. CUG provides networking opportunities, technical presentations and ongoing working groups that can benefit your ... [ Read More ]

Supercomputing Matters: SC14 in Retrospect

SC14-BLOG

SC14, the premier event in the HPC industry, has wound to a close in New Orleans. It’s interesting to look back and contemplate the validity of this year’s theme, “HPC Matters,” the success of the conference and the vitality of the industry. Our industry has seen the ebb and flow of the relevance of supercomputing, and the fortunes of Cray have often paralleled those of this event (or visa versa). This year was no exception and SC14 was a resounding success for Cray and for the industry. With more than  10,000 attendees and 356 exhibitors it was a full show and the work never stopped. As I walked the show floor — logging about 5 miles a day — I was struck by the number of Cray customers. They were everywhere, either with booths of their own ... [ Read More ]

Chapel at SC14: Making Big Easy

Chapel_SC14Blog

It’s been a big year for the Chapel team at Cray. In the past 12 months, we’ve doubled the size of our team, and with that expansion have been able to significantly accelerate the strides we’re taking. Here are a few notable accomplishments that occurred in 2014: Released two new versions of Chapel, the most recent of which, version 1.10, was made available on Oct. 2. Across these two releases, we’ve made significant performance improvements, enhanced our standard modules and I/O support, added initial support for Intel® Xeon® Phi Knights Corner (KNC) and continued refining the language’s productivity-oriented features. Held our first Chapel Implementers and Users Workshop (CHIUW) at IPDPS in May, highlighting work being done in ... [ Read More ]
