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 … [Read more...]

Baseball’s Lesson for Analytics

Baseball

In the immediate aftermath of an enthralling baseball World Series (go Giants!), it’s not surprising that it’s taking a while to get out of baseball mode. I did not have the benefit of growing up with baseball, so my baseball education happened later in life, but I daresay there’s quite a bit of strategy in the game. The value of getting the matchup part of the strategy right is evidenced by the cutting-edge research in this space, but that’s a topic for another day. Another concept brought up at various points in the World Series that I found intriguing was batters “going with the pitch” to increase their chances of a positive result on the play. This means recognizing the pitch and hitting the ball to right or left field … [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 … [Read more...]

Unlocking the Full Potential of Health Data

ORNL_BlogImage

The health care industry is facing a challenging transition as it tries to use data more effectively. Gathering, sharing and analyzing patient information is an incredibly challenging process that is contributing to a technological revolution across the health care sector. One of the main challenges in our health care system today is the difficulty in working with patient data, because it exists in a variety of formats, both structured and unstructured, and it often exists in large volumes, making it difficult to handle in many data centers. This is where supercomputing comes into play, and the Oak Ridge National Laboratory (ORNL) is leading a project that is taking key steps forward in driving innovation. According to a recent … [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...]
