The implementation of a first-generation CELL processor that supports multiple operating systems including Linux consists of a 64b power processor element (PPE) and its L2 cache, multiple synergistic processor elements (SPE) [1] that each has its own local memory (LS) [2], a high-bandwidth internal element interconnect bus (EIB), two configurable(More)
Over the past several years, computational scientists have observed a frustrating trend of stagnating application performance despite dramatic increases in peak performance of high performance computers. In and IBM proposed a new process to reverse this situation [1]. This strategy is based on new types of development partnerships with computer vendors(More)
and cell library codevelopment for improving redundant via insertion at pins, " in Proc. Abstract—Statistical analysis of computations per unit energy in processors over the last 30 years is given that illustrates a sharp reduction in the rate of energy efficiency improvements over the last several years resulting in the formation of an asymptotic " wall "(More)
The CELL processor [1] jointly developed by Sony, Toshiba, and IBM provides a great potential for scientific computing with a peak performance in single precision of 204.8 Gflop/s. But, this performance is obtained with an SIMD processor which uses single precision floating numbers with a rounding mode toward zero. The goal of our work is to develop(More)
Shadows are of great importance to computer graphics, especially for interactive animation , due to the visual cues which they provide. Most research in the field of dynamic shadowing has focussed on shadows from point light sources, since they are much easier to compute than those from area lights. This means that such shadows have sharp boundaries, and so(More)
1. Diplopia may require a simple change in the patient's glasses, various types of surgical correction, or even treatment for a life-threatening condition. Your job is to determine the urgent nature of the problem and have the patient scheduled in your office, clinic, or hospital appropriately. 2. When questions of diplopia arise, establish whether the(More)
