Is there someone who can give a relatively simple rundown of the new technology called "transactional memory"? Why is this kind of memory starting to pop up now (Blue Gene/Q, POWER8, Haswell,…) and ...

At Hot Chips last week, IBM talked about BlueGene/Q, the processor powering the 20 petaflops Sequoia supercomputer. Designed for power-efficient floating point processing, the processor has one ...

Transactional memory systems represent a paradigm shift in concurrent programming by abstracting low-level lock management and enabling sequences of operations to be executed as atomic transactions.

Multicoreinfo.com has a pair of pointers to ACM Queue articles pro and con transactional memory in parallel programming for multicore systems. From the (mostly) pro article it is clear that the ...

PALO ALTO, CA—IBM has become the first company to ship a commercial microprocessor using transactional memory, a new feature for multicore chips researchers have studied for years. The BlueGene/Q ...

Sun's forthcoming "Rock" chip has hardware support for two features not found in other widely used CPUs: thread scouting and transactional memory. The hardware scout component isn't a technology I ...

With the increasing use of multicore CPUs in computers, programmers have to learn new techniques for parallel processing. One very promising approach is transactional memory. The primary problem for ...
