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...]

Pushing the Edge of Big Data at Strata+Hadoop World 2014

TahomaBlog

Last week I published a blog article about our new Urika-XA™ open platform for extreme analytics. This week, I’d like to tell you about its official launch at the Strata+Hadoop World 2014 conference in the Big Apple. Big data and its entire ecosystem is a dynamic animal and this was evident at Stata+Hadoop World. I’ve attended several of these conferences and other big data events over the years and it’s exciting to see how the user base has changed and grown tremendously. Several of the other vendors I spoke with (who by now are close friends since we always run into each other at conferences) made the same remark. Three years ago, Hadoop World had a smattering of actual users with just a few folks who were at the pilot stage and very … [Read more...]

RTM: Essential Imaging for the Oil and Gas Sector

SEG RTM featured image

Reverse time migration (RTM) modeling is a critical component in the seismic processing workflow of oil and gas exploration. RTM imaging enables more accurate imaging in areas of complex structures and velocities by gathering a two-way acoustic image of seismic data in place of a one-way image. As this definition implies, it means creating and analyzing much more data with every seismic model, something that can be incredibly daunting — traditional simulations are already complex and require significant resources. RTM comes in many flavors and is rapidly evolving. Its growth is driving increased geophysical processing requirements: vertical transverse isotropy, tilted transversely isotropic media, least squares/residual shot RTM (aka … [Read more...]

Student Teams Prepare for Cluster Showdown

TeamVibe_Logo-01

The annual Supercomputing conference, which will be held this year Nov. 16-21 in New Orleans, Louisiana, is a can’t-miss event for the supercomputing world. It’s five days of exhibits, conferences and networking that showcase current innovations in the industry. It’s also the forum for the Student Cluster Competition (SCC), a 48-hour, nonstop challenge for 12 teams of undergraduate and/or high school students. Their mission: Assemble a small cluster computer and race to demonstrate the greatest sustained performance on several applications, three of which they’ll know in advance and one that’s a mystery until the competition starts. The only restrictions on hardware are that the teams must not exceed the 3,120-watt power limit (gasp!) … [Read more...]
