Beating Floating Point at its own game: Posit Arithmetic

“Dr. Gustafson has recently finished writing a book, The End of Error: Unum Computing, that presents a new approach to computer arithmetic: the unum. The universal number, or unum format, encompasses all IEEE floating-point formats as well as fixed-point and exact integer arithmetic. This approach obtains more accurate answers than floating-point arithmetic yet uses fewer bits in many cases, saving memory, bandwidth, energy, and power.”

Many-Task Computing for Grids

Many-task computing aims to bridge the gap between two computing paradigms, high throughput computing and high performance computing.
