Abstract: Processors in a compute node offload transactional memory accesses addressing shared memory to a transactional memory agent. The transactional memory agent typically resides near the processors in a particular compute node. The transactional memory agent acts as a proxy for those processors. A first benefit of the invention includes decoupling the processor from the direct effects of remote system failures. Other benefits of the invention includes freeing the processor from having to be aware of transactional memory semantics, and allowing the processor to address a memory space larger than the processor's native hardware addressing capabilities. The invention also enables computer system transactional capabilities to scale well beyond the transactional capabilities of those found computer systems today.
