Recent research suggests that DSM clusters can benefit from parallel coherence controllers. Parallel controllers requires address partitioning and synchronization to avoid handling multiple coherence events for the same memory address simultaneously. This ...
In this paper, we present the first system that implement OpenMP on network of shared-memory multiprocessors. This system enables the program to rely on a single, standard, shared-memory API for parallelization within a multiprocessor and between multiproc ...
On-line services are making increasing use of dynamically generated Web content. Serving dynamic content is more complex than serving static content. Besides a Web server, it typically involves a server-side application and a database to generate and store ...
We describe an implementation of a sizable subset of OpenMP on networks of workstations (NOWs). By extending the availability of OpenMP to NOWs, we overcome one of its primary drawbacks compared to MPI, namely lack of portability to environments other than ...
In this paper, we present the first system that implements OpenMP on a network of shared-memory multiprocessors. This system enables the programmer to rely on a single, standard, shared-memory API for parallelization within a multiprocessor and between mul ...
In practice, concurrent programming systems based on message passing are often instantiations of the actor model. A popular implementation of this form of concurrency is the Erlang programming language. Erlang supports massively concurrent systems such as ...
Recent proposals for Chip Multiprocessors (CMPs) advocate speculative, or implicit, threading in which the hardware employs prediction to peel off instruction sequences (i.e., implicit threads) from the sequential execution stream and speculatively execute ...
We compare the performance of software-supported shared memory on a general-purpose network to hardware-supported shared memory on a dedicated interconnect. Up to eight processors, our results are based on the execution of a set of application programs on ...
We believe the paucity of massively parallel, shared-memory machines follows from the lack of a shared-memory programming performance model that can inform programmers of the cost of operations (so they can avoid expensive ones) and can tell hardware desig ...
On a distributed memory machine, hand-coded message passing leads to the most efficient execution, but it is difficult to use. Parallelizing compilers can approach the performance of hand-coded message passing by translating data-parallel programs into mes ...
