Two radically different parallel computers prompt a debate about the best parallel architectures and may mark the commercial viability of parallelism on the supercomputer scale.

Toward real-time performance benchmarks for Ada

Benchmarks are developed to measure the Ada notion of time, the Ada features believed important to real-time performance, and other time-related features that are not part of the language, but are part of the run-time system; …

Comments on "Grosch's law re-revisited: CPU power and the cost of computation"

Taking Ein-Dor's recent reevaluation of Grosch's law one step further, the authors find evidence of different slopes for different classes of computers and the utility of an additional variable: the IBM or IBM-compatible factor …
