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...]

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...]
