An Argument for Simple COMA
We present design details and some initial performance results of a novel scalable shared memory multiprocessor architecture that incorporates the major strengths of several contemporary multiprocessor architectures while avoiding their most serious weaknesses. Speciically, our architecture design incorporates the automatic data migration and replication features of cache-only memory architectu...
متن کاملEnhancing Memory Use in Simple Coma: Multiplexed Simple Coma
Scalable shared-memory multiprocessors that are designed as Cache-Only Memory Architectures (Coma) allow automatic replication and migration of data in the main memory. This enhances programmability by hopefully eliminating the need for data distribution strategies and page migration schemes. Recently, a variant of Coma called Simple Coma has been proposed as a lower-cost alternative to hardwar...
متن کاملSimple COMA Node Implementations
Shared memory architectures often have caches to reduce the number of slow remote memory accesses. The largest possible caches exist in shared memory architectures called Cache-Only Memory Architectures (COMAs). In a COMA all the memory resources are used to implement large caches. Unfortunately, these large caches also have their price. Due to its lack of physically shared memory, COMA may su ...
متن کاملA simple and useful coma scale for patients with neurologic emergencies: the Emergency Coma Scale.
OBJECTIVES The Emergency Coma Scale (ECS) was developed in Japan in 2003. We planned a multicenter study to evaluate the utility of the ECS by comparison of the ECS and the Glasgow Coma Scale (GCS). METHODS Ten medical facilities, including 4 university hospitals in Japan, participated in this study. We evaluated and recorded the level of consciousness, using the ECS and GCS, of all patients ...
