This could be something very *Large* for the entire US tech industry: Sun rallies industry around Rock CPU Group may back approach to atomic transactions Rick Merritt EE Times (01/30/2008 6:30 PM EST) SAN JOSE, Calif. — Sun Microsystems is trying to rally an industry consortium around its approach to supporting transactional memory, a key piece of the puzzle of tomorrow's parallel programming systems. The move comes at a time when Sun hopes to be the first to implement the technology in a server microprocessor. Sun will describe its Rock processor in a paper at the International Solid-State Circuits Conference in San Francisco Monday (Feb. 4). Abstracts released by ISSCC show the 2.3 GHz Rock aims to be the first CPU to implement transactional memory, also known as atomic transactions. By tagging groups of instructions to execute at essentially the same time, the technique reduces the complexity and inefficiency of current locking mechanisms used to synchronize operations, especially in large database software. Computer scientists have long seen the feature as one of the initial planks of a new parallel programming model that will be needed for multi-core architectures. eetimes.com 0\|0
