Over the last five decades, microprocessors have gotten cheaper and more powerful as predicted by Gordon Moore’s famous observation, which states that the number of transistors on an integrated circuit doubles every two years. However, the limits of miniaturization can only go so far before crossing the quantum threshold. Currently there is some progress left Read more…
Graphene is a one-atom-thick layer of carbon that has been hailed as a potential silicon replacement capable of extending the exponential computing advances that modern society has come to depend on. Despite the material’s profile of being strong, flexible, light-weight and a good conductor, there are still a number of challenges that must addressed before Read more…
As transistors approach the limits of miniaturization, the rapid pace of progress in the microprocessor industry is destined to start declining unless researchers are successful in innovating alternative designs. The best and brightest minds of our time are hard at work developing the next generation of microprocessors so essential to supercomputers, handheld devices and worldwide Read more…
<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/future_datacenter_small.jpg” alt=”” width=”99″ height=”88″ />While much attention has focused on China’s rising supercomputing prospects lately, a number of other countries, including Russia, are also quickly muscling up their HPC resources. With their eyes set on exascale, Russia is planning to invest over a billion dollars this decade to field at least one such system by 2020.
For the past several years, Field Programmable Gate Arrays (FPGAs) have been getting large enough to compete with microprocessors in floating-point performance. Using the theoretical peak performance numbers, the FPGA’s floating-point performance is growing faster than microprocessors. This article calculates the peak performance for several FPGA devices from Xilinx and compares them to a reference microprocessor for equivalent time periods and shows that this gap in performance is growing.
CPU will include new Advanced Vector Extension instructions.
A few thoughts on two of my favorite topics.
Multicore processors are racing forward, but software is lagging — and may never catch up.
Advanced Micro Devices said Tuesday that it would split into two companies — one focused on designing microprocessors and the other on the costly business of manufacturing them.
