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 … [Read more...]

Using HPC Techniques to Accelerate NGS Workflows

Life Sciences_small

Next-generation sequencing (NGS) describes the modern nucleotide sequencing technologies that allow analysis of genetic material with unprecedented speed and efficiency. Its advent is shifting genome assembly from a problem of laboratory-based chemistry to one well suited to high performance computing (HPC). In simple terms, NGS involves breaking up long DNA or RNA molecules into millions of small, fragments (50 to 200 nucleotides), defined as a “reads” to be assembled into larger fragments called contigs. The process of taking genetic material, processing it on a sequencer, passing it to an HPC system for assembly, and outputting digital information in a form useful for research is contained in a “workflow,” the end-to-end flow … [Read more...]

Video Blog: Solutions that Enable Life Sciences Advances

Ted Slater

Advanced IT solutions are transforming the life sciences industry, and there are few better places to learn about how this is happening than the Bio-IT World Conference & Expo in Boston. The conference is coming up soon, and at Cray, we're excited to highlight our computing, storage and analysis solutions. Ted Slater, senior solutions architect for life sciences at YarcData, a Cray company, will present on Wednesday, April 30, and talk about how YarcData’s Urika technology is fueling major advances. Ted's presentation, "Learn How YarcData's Graph Analytics Appliance Makes It Easy to Use Big Data in Life Sciences," is about how data-intensive research is rising in life sciences and how YarcData systems provide the functionality … [Read more...]

CUG’14 Just Around the Corner

CUG_BlogAd

It’s time again for the annual Cray User Group meeting. This year’s event will be hosted by the Swiss National Supercomputing Centre (CSCS) in the picturesque town of Lugano, Switzerland. From May 4-8 Cray users and system owners from around the world will congregate to collaborate and share their experiences. A contingent of Cray employees will join them to hear straight from the customer and to present tutorials and technical papers. While the conference will include several interesting networking events in beautiful venues, this is first and foremost a technical conference whose goal is to facilitate collaboration and information exchange in the Cray user community. This annual conference gives CUG members the opportunity to share … [Read more...]
