Imagine a world with electronic devices that can power themselves, music players that hold a lifetime of songs, self-healing batteries, and chips that can change abilities on the fly. Based on what’s going on in America’s research laboratories, these things are not only possible, but likely.
“The next five years will be a very [...]

During the final keynote of IDF, Intel’s Justin Rattner demonstrated a new stacked DRAM technology called the Hybrid Memory Cube (HMC). The need is clear: if CPU performance is to continue to scale, there can’t be any bottlenecks preventing that scaling from happening. Memory bandwidth has always been a bottleneck we’ve [...]

Since 1965, Moore’s Law has served as a benchmark for the computer hardware industry, pushing vendors to double the processing power of computing equipment every 18 months or so. It turns out that computers have doubled in energy efficiency at about the same rate, according to a new study co-authored by data-center-power [...]

Debugging is not something I enjoy doing but sometimes I cannot avoid doing… Therefore I thought that a short overview on some of the available tools will be helpful.
- TotalView: is probably the most widely used debugger for parallel programs. It can be used with C, C++ and Fortran programs and it supports all common [...]

Why do we, as researchers and practitioners, have this deep and abiding love of computing? Why do we compute? Superficially, the question seems as innocuous as asking why the sky is blue or the grass is green. However, like both of those childhood questions, the simplicity belies the subtlety beneath. Just ask someone [...]

Just over a year ago Seagate introduced the world’s first 3TB hard drive. Although it shipped in an enclosure for external use, the Seagate GoFlex Desk was available with the very first 3.5” 3TB SATA hard drive. A couple of months later Seagate and Western Digital both followed up with standalone [...]
