Back in the 1960s the IBM 1401 was both state of the art and an engineering marvel. It filled up an entire room and weighed thousands of pounds; in today’s money it would cost about $1.5 million. The old 1401 could perform just over 4,000 calculations per second and at the time was virtually unmatched. [...]

From Wikipedia, the free encyclopedia In a computer’s central processing unit (CPU), an accumulator is a register in which intermediate arithmetic and logic results are stored. Without a register like an accumulator, it would be necessary to write the result of each calculation (addition, multiplication, shift, etc.) to main memory, perhaps only to be read [...]

From Wikipedia, the free encyclopedia This article is about the use of benchmarks in computing, for other uses see benchmark. In computing, a benchmark is the act of running a computer program, a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of [...]

Create Strong, Effective Passwords All OSU students, faculty and staff and those with guest accounts have a responsibility to keep their computing as secure as possible. Never share your OSU e-mail account with anyone else; it is against the university’s Responsible Use policy. In addition, follow these rules for ensuring password security: Create strong passwords [...]

Quick read Los Alamos scientists doubled the processing speed of the former computing champ. Roadrunner, the new hybrid supercomputer, uses a video game chip to propel performance to more than a thousand trillion calculations per second. Scientists want faster, more powerful high-performance supercomputers to simulate complex physical, biological, and socioeconomic systems with greater realism and [...]

Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects. The animal featured on the cover of High Performance Computing is the Northern harrier (also known as the hen harrier or marsh [...]

Who says safe computing must remain a pipe dream? By Bruce Schneier CNet News.com December 9, 2004 Spanish translation I am regularly asked what average Internet users can do to ensure their security. My first answer is usually, “Nothing–you’re screwed.” But that’s not true, and the reality is more complicated. You’re screwed if you do [...]

Remember the first day you owned your current computer? You probably couldn’t believe how fast it was, especially if it replaced a slower predecessor. Applications snapping open, once-lengthy processes completed in a fraction of the time, and graphics and animation flowing as smooth as television programming. You probably could not imagine a day when you [...]
