System enables large speedups — as much as 88-fold — on common parallel-computing algorithms (MIT)


Source: MIT/ CSAIL: Suvinay Subramanian, Mark C. Jeffrey, Maleen Abeydeera, Hyun Ryong Lee, Victor A. Ying, Joel Emer, Daniel Sanchez As is commonly known, the chips in most modern desktop computers have four cores or processing units, which can run different computational tasks in parallel, but that the chips of the future could have dozens or even hundreds of cores, and taking advantage o... » read more

The Limits Of Parallelism


Parallelism used to be the domain of supercomputers working on weather simulations or plutonium decay. It is now part of the architecture of most SoCs. But just how efficient, effective and widespread has parallelism really become? There is no simple answer to that question. Even for a dual-core implementation of a processor on a chip, results can vary greatly by software application, operat... » read more

Virtualization Revisited


Virtual instruction set computing (VISC) is getting a second look as power and performance improvements begin to slow and [getkc id="74" comment="Moore's Law"] is supplanted by [getkc id="279" comment="Koomey's Law"]. While the current crop of [getkc id="185" kc_name="finFETs"] will likely be extended for at least one more process node, there is some debate about what comes next, whether tha... » read more
