....components and interconnected with System Area Networks (SANs) are becoming increasingly popular, largely due to their attractive price performance ratio. Advances in System Area Network technology have introduced native support for shared memory abstractions. These Shared Memory Clusters [1] combine the cost efficiency and scalability of clusters with the programmability and fast communication support of shared memory multiprocessors. They thereby form a competitive alternative to tightly coupled large scale SMPs or CC NUMA machines. These cluster architectures face the challenge of ....
....SMPs or CC NUMA machines. These cluster architectures face the challenge of maintaining memory consistency in a loosely coupled SAN environment. The I O bus based architectures of such SANs prevent access to the coherence traffic from the SAN NICs. To overcome this problem, Heinrich et al. [1] maintain consistency via special hardware coherence controllers on top of an Infinibandbased scalable SAN fabric. Their scheme supports the same programming abstraction as the successful CC NUMA architectures (e.g. the Origin 2000 [2] but at a much lower system cost. Nonetheless, their ....
