The earliest paper on Transactional Memory that can be found – Transactional Memory: Architectural Support for Lock-Free Data Structures – was written about twenty years ago. It’s hard to say what all ...

Executing a notion of a transaction, and doing it without any such locks, is also one of the attributes of transactional memory. Before I go on, although the term transactional memory is based on all ...

Transactional memory systems represent a significant advancement in concurrent programming by allowing grouped sequences of operations to execute atomically. This paradigm reduces the complexity ...

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.

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 ...

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 ...

Editor's Note: Multicore architectures find use across a diverse range of applications thanks to their performance and efficiency. By combining several general-purpose MCU cores — or MCU cores and ...

Hardware transactional memory isn't a new thing. It's a feature that's been around for quite a while on a number of different microchip architectures found in expensive lines of server hardware. But ...

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 ...

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 ...

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 ...
