TeraGrid is a national-scale computational science facility supported through a partnership among thirteen institutions, with funding from the US National Science Foundation [1]. Initially created through a Major Research Equipment Facilities Construction (MREFC [2]) award in 2001, the TeraGrid facility began providing production computing, storage,(More)
There is considerable interest in achieving a 1000 fold increase in supercomputing power in the next decade, but the challenges are formidable. In this chapter, the authors discuss some of the driving science and security applications that require Exascale computing (a million, trillion operations per second). Key architectural challenges include power,(More)
has been studying the use of hand-held devices at the same time as other computing devices. As people move about the world, they will be entering and leaving spaces where there are embedded or desktop computers, such as offices, conference rooms, classrooms, and even "smart homes." We are exploring the many issues surrounding how to have the user interface,(More)
This manuscript has been read and accepted for the Graduate Faculty in Music to satisfy the dissertation requirement for the degree of Doctor of Philosophy. 1 argues that suspending intelligibility stimulates the audience to imagine alternative meanings and ways the music might go, in an orientation that is politically desirable. Synthesizing theorizations(More)
Alternatives to conventional rigid fusion have been proposed for several conditions related to degenerative disc disease when nonoperative treatment has failed. Semirigid fixation, in the form of dynamic stabilization or PEEK rods, is expected to provide compression under loading as well as an intermediate level of stabilization. This study systematically(More)
Computing Technology Changes the Way in Which We do Computational Chemistry. Abstract Developments in Computational Quantum Chemistry have been driven by the developments in hardware and software technology. Quantum chemical applications use 30-40% of the computational resources available in National and Regional supercomputer centers, therefore, it is(More)
