Cray Inc. and Alliant Geophysical to Provide Seismic Solutions for the Petroleum Energy Industry.Business Editors/High-Tech Writers SEATTLE & HOUSTON--(BUSINESS WIRE)--Sept. 7, 2001 Cray T3E The Cray T3E was Cray Research's second-generation massively parallel supercomputer architecture, launched in 1995. Like the previous Cray T3D It was a fully distributed memory machine using a 3D torus topology interconnection network. Supercomputer and Alliant Geophysical Imaging Software Will Power High-Performance Finite Difference Depth Migration for Oil Companies Global supercomputer leader Cray Inc. (Nasdaq:CRAY) and Alliant Geophysical, a privately held seismic solutions provider, today announced a collaboration to reduce the turnaround time (1) In batch processing, the time it takes to receive finished reports after submission of documents or files for processing. In an online environment, turnaround time is the same as response time. of depth imaging projects for oil companies. The companies agreed to make Alliant Geophysical's unique 3D prestack depth migration software run optimally on Cray T3E(TM) highly scalable supercomputer systems Three firms have held, simultaneously, the name Supercomputer Systems or Supercomputing Systems. The first was founded by Steve Chen, architect of the Cray X-MP and Cray Y-MP. The second was based in San Diego, California, USA. . Three-dimensional prestack depth migration is a technique for "imaging" oil and gas reserves from seismic data, and is used to improve the odds for finding oil. The Alliant software, 3DWAVE, employs the shot-record finite difference method In mathematics, more precisely in numerical analysis, finite differences play an important role, they are one of the simplest ways of approximating a differential operator, and are extensively used in solving differential equations. , a technique that is more accurate, but also more computationally intensive, than the established Kirchhoff method. The Kirchhoff method for 3D prestack depth migration first became feasible with the introduction of prior-generation Cray(R) supercomputers in the mid-1990s. The companies said the initial software porting has been completed and optimization work will be complete by year-end. As part of the collaboration agreement, Cray has delivered a Cray T3E system to Alliant for the company's use in this commercial effort. In return, Cray T3E systems and subsequent Cray supercomputers to which the Alliant software is ported will be the first supercomputer-class platforms for Alliant's 3D prestack depth migration software, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. George Stephenson, head of petroleum industry sales for Cray Inc. "Several parties have been trying to do 3D prestack depth migration using the finite difference method, with only nominal success," said Stephenson. "This is a demanding application, and the Cray T3E system offers the extreme scalability and high efficiency for large workloads indicative of this important class of solution. Alliant's software produces the first commercial-oriented solution tailored for large-scale projects." The Cray T3E system is widely recognized as the most technically successful highly scalable computer and set the world record for sustained performance on a full 64-bit application. "The Cray T3E system is the ideal platform for our leading edge prestack imaging solutions," said Craig Limbaugh, president of Alliant Geophysical. "The system delivers the combination of processor performance, inter-processor communication, bandwidth and scalability to handle our advanced imaging and demanding applications efficiently. By optimizing our software for the Cray T3E system, we will provide customers the quality, performance and affordability that this emerging market demands. "Faster turnaround time benefits our clients because this gives them more time to investigate the oil exploration opportunity without the loss of quality; and in this business, time is money," added Limbaugh. About Alliant Geophysical Alliant Geophysical is a closely held company Closely held company A company who has a small group of controlling shareholders. In contrast, a widely-held firm has many shareholders. It is difficult or impossible to wage a proxy battle for any closely-held firm. that provides sophisticated oil and gas exploration services, including comprehensive seismic data analysis, prestack migration and direct hydrocarbon analysis that was once restricted to the largest oil companies.
