Concerns over rising soft-error rates in processor logic has led to numerous proposals for error tolerance mechanisms. In this paper, we examine the role of soft-error containment in a shared memory multiprocessor. We study a range of design alternatives b ...
Coherence misses in shared-memory multiprocessors account for a substantial fraction of execution time in many important scientific and commercial workloads. Memory streaming provides a promising solution to the coherence miss bottleneck because it improve ...
In shared memory programs contention often occurs at the transition between a sequential and a parallel section of the code. As all threads start executing the parallel section, they often access data just modified by the thread that executed the sequentia ...
In this paper, we describe Teapot, a domain-specific language for writing cache coherence protocols. Cache coherence is of concern when parallel and distributed systems make local replicas of shared data to improve scalability and performance. In both dist ...
Coherent read misses in shared-memory multiprocessors account for a substantial fraction of execution time in many important scientific and commercial workloads. We propose Temporal Streaming, to eliminate coherent read misses by streaming data to a proces ...
Recent research indicates that prediction-based coherence optimizations offer substantial performance improvements for scientific applications in distributed shared memory multiprocessors. Important commercial applications also show sensitivity to coherenc ...
Unlike compiler-generated message-passing code, the coherence mechanisms in shared-memory systems work equally well for regular and irregular programs. In many programs, however compile-time information about data accesses would permit data to be transferr ...
In this paper we describe our experience with Teapot [7], a domain-specific language for writing cache coherence protocols. Cache coherence is of concern when parallel and distributed computing systems make local replicas of shared data to improve scalabil ...
Software fine-grain distributed shared memory (FGDSM) provides a simplified shared-memory programming interface with minimal or no hardware support. Originally software FGDSMs targeted uniprocessor-node parallel machines. This paper presents Sirocco, a fam ...
This paper compares several implementations of entry consistency (EC) and lazy release consistency (LRC), two relaxed memory models in use with software distributed shared memory (DSM) systems. We use six applications in our study: SOR, Quicksort, Water, B ...
