Intel incorporates Eliot Moss’s research into its new chips

Fri February 10, 2012

Intel has just announced that forthcoming multicore CPUs will incorporate hardware transactional memory, bringing a proposal made by Professor Eliot Moss and co-author Maurice Herlihy in their seminal 1993 paper on “Transactional Memory” to mainstream computing.

As described in their paper, “Transactional Memory: Architectural Support for Lock-Free Data Structures,” transactional memory allows programmers to define customized read-modify-write operations that apply to multiple, independently-chosen words of memory. It is implemented by straightforward extensions to any multiprocessor cache-coherence protocol.

Their paper, which has been cited over 1300 times, received the Most Influential Paper Award at the 2008 International Symposium on Computer Architecture. According to the ACM Special Interest Group on Computer Architecture (SIGARCH), the Award recognizes the paper from the ISCA Proceedings 15 years earlier that has had the most impact on the field (in terms of research, development, products or ideas) during the intervening years.
