Parallel computers are becoming more powerful and more complex in response to the demand for computing power by scientists and engineers. Inevitably, new and more complex I/O systems will be developed for these systems. In particular we believe that the I/O system must provide the programmer with the ability to explicitly manage storage (despite the trend(More)
Dense linear systems of equations are quite common in science and engineering, arising in boundary element methods, least squares problems and other settings. Massively parallel computers will be necessary to solve the large systems required by scientists and engineers, and scalable parallel algorithms for the linear algebra applications must be devised for(More)
Our current understanding on the pathogenesis of abdominal aortic and intracranial aneurysms is limited, but genetic and environmental factors as well as their interactions are likely to play important roles in the development and rupture of aneurysms. To identify genetic factors contributing to these diseases, we are carrying out genome-wide screening(More)
