Back to Warp Speed, Scotty!

DataWarpBlog

Aren’t supercomputers already supposed to be moving at “warp” speed? Well, multi-petaflops anyway? With computing challenges getting more demanding and datasets getting more massive, it is not as easy as Captain James Kirk asking Scotty for more power. Supercomputers and their associated storage systems are getting larger each year, but a performance inefficiency is emerging between the compute nodes and the disk systems where the parallel file systems are located. The overall performance of application execution on supercomputing systems is subject to the efficiency of the data movement between a tier of spinning disks and the memory where the codes are actually executing. Cray has been collaborating with some of the most … [Read more...]

Oktoberfest: Prost! to Beer and Big Data

Octoberfest_Blog

Bavarian culture has spread its wings and has influenced the world with its beer-drinking tradition. Oktoberfest, a more than 200-year-old celebration that began in Munich, Germany, is still well under way. These days, Oktoberfest is celebrated not only in Bavaria, but also around the globe in places such as London and Dublin and many cities in the United States. As an enthusiast of both beer and data, I find myself thinking about how even beer production and marketing relate to big data. Even in the world of Oktoberfest, there is a massive amount of information to be mined, analyzed and put to use. Questions such as “What types beer are sold the most?” and “Depending on the time, day, place and weather, which areas host the … [Read more...]

Q&A: Diving Deep Into Our Solar System

ORLN_BlogImage

Anthony Mezzacappa, director of the University of Tennessee–Oak Ridge National Laboratory Joint Institute for Computational Sciences, and a team of computational astrophysicists are conducting one of the largest supernova simulations to date on ORNL’s “Titan” supercomputer. Titan, which is a hybrid Cray® XK7™ supercomputer, is managed by the Oak Ridge Leadership Computing Facility on behalf of the Department of Energy. Dr. Mezzacappa answers our questions about his team’s work on Titan. Q: Why is understanding what triggers a supernova explosion so important? A: Supernovae are ultimately responsible for why you and I are here. The class of supernova that our team studies is known as core-collapse supernovae, and this type … [Read more...]

Recent Crash Test Results Highlight the Need for Enhanced Simulation

IIHS small crash

In July the Insurance Institute for Highway Safety (IIHS) published crash test results for the “small overlap front crash test,” in which only one of the 12 cars tested earned a “good” rating.  These results, combined with the results of earlier tests, led Consumer Reports to publish a headline reading, “Most Small Cars Bomb New Small-Overlap Crash Test.” At the same time, Nissan presented an excellent paper on the computer simulation challenges of the small overlap test. This is an example of the increasingly stringent requirements for automotive safety and why the use of high performance computing (HPC) for crash safety simulation is critical in the automotive design process. There are dozens of crash load cases evaluated … [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...]
