Recent research advocates using general message predictors to learn and predict the coherence activity in distributed shared memory (DSM). By accurately predicting a message and timely invoking the necessary coherence actions, a DSM can hide much of the re ...
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 ...
This paper summarizes how distributed shared memory (DSM) can be both efficiently and portably supported by the Tempest interface. Tempest is a collection of mechanisms for communication and synchronization in parallel programs. These mechanisms provide co ...
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 ...
Recent research has offered programmers increased options for programming parallel computers by exposing system policies (e.g., memory coherence protocols) or by providing several programming paradigms (e.g. message passing and shared memory) on the same p ...
Distributed shared memory 8DSM) is an abstraction of shared memory on a distributed memory machine. Hardware DSM systems support this abstraction at the architecture level; software DSM systems support the abstraction within the runtime system. One of the ...
The paper describes Tempest, a collection of mechanisms for communication and synchronization in parallel programs. With these mechanisms, authors of compilers, libraries, and application programs can exploit-across a wide range of hardware platforms-the b ...
The paper discusses implementations of fine-grain memory access control, which selectively restricts reads and writes to cache-block-sized memory regions. Fine-grain access control forms the basis of efficient cache- coherent shared memory. The paper focus ...
Future parallel computers must efficiently execute not only hand-coded applications but also programs written in high-level, parallel programming languages. Today’s machines limit these programs to a single communication paradigm, either message-passing or ...
Message passing and shared memory are two techniques parallel programs use for coordination and communication. This paper studies the strengths and weaknesses of these two mechanisms by comparing equivalent, well-written message-passing and shared-memory p ...
