DDM - A Cache-Only Memory Architecture
Single bus. Shared-memory systems based on a single bus have some tens of processors, each one with a local cache, and typically suffer from bus saturation. A cache-coherence protocol in each cache snoops the traffic on the common bus and prevents inconsistencies in cache contents.’ Computers manufactured by Sequent and Encore use this kind of architecture. Because it provides a uniform access ...
متن کاملDdm { a Cache - Only
The long latencies introduced by remote accesses in a large multiprocessor can be hidden by caching. Caching also decreases the network load. We introduce a new class of architectures called Cache Only Memory Archi-tectures (COMA). These architectures provide the programming paradigm of the shared-memory architectures, but have no physically shared memory; instead, the caches attached to the pr...
متن کاملAnalytic Model of a Cache Only Memory Architecture
Abs t r ac t . An approximate analytic model of a shared memory multiprocessor with a Cache Only Memory Architecture (COMA), the busbased Data Difussion Machine (DDM), is presented and validated. It describes the timing and interference in the system as a function of the hardware, the protocols, the topology and the workload. Model results have been compared to results from an independent simul...
متن کاملCache-Only Memory Architectures
72 Computer S calable shared-memory multiprocessors are emerging as attractive platforms for applications with high-performance demands. What makes these machines attractive is the shared address space, which allows processors in a multiprocessor to share data the same way it is shared by multiple processes in a sequential machine. The shared-memory paradigm makes it easier to write parallel pr...
متن کاملRelaxing the Inclusion Property in Cache Only Memory Architecture
Cache only memory architecture (COMA), even with its additional memory overhead, can incur longer inter/intra-node communication latency than cache-coherent nonuniform memory access (CC-NUMA). Some studies on COMA suggest that the inclusion property applied between the processor cache and its local memory is one of the major causes of less-than-desirable performance. The inclusion property crea...
