Cache-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 کاملToward Scalable Cache Only Memory Architectures
H IGH PERFORMANCE at a low cost is the common goal of most new computers. Even if the speed of microprocessors seems to double every year, there are, and will always be, important applications demanding even better performance. There are two ways of meeting this demand: a single processor designed with exclusive technology, or several processors in cooperation. The sharedmemory model allows the...
متن کاملAutomatic Scheduling for Cache Only Memory Architectures
For parallel and distributed systems to gain wider acceptance than they have to date, they must become significantly easier to program. Fundamentally, parallel programming is more difficult than sequential programming as long as data and computation must be distributed by the programmer. Cache Only Memory Architectures (COMAs) provide a Distributed Shared Memory (DSM) where data distribution is...
متن کاملDDM - 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 کاملThe Application of Skewed-Associative Memories to Cache Only Memory Architectures
Skewed-associative caches use several hash functions to reduce collisions in caches without increasing the associativity. This technique can increase the hit ratio of a cache without significantly increasing the cost. In this paper we apply skewing to solve a problem particular to virtual shared memory architectures that are designed using only associative memories. When using ordinary setassoc...
