Low-level router design and its impact on supercomputer system performance
Supercomputer performance is highly dependent on its interconnection subsystem design. In this paper we study how di erent architectural approaches for router design impact into s...

Improving the performance of speculatively parallel applications on the Hydra CMP
Hydra is a chip multiprocessor (CMP) with integrated support for thread-level speculation. Thread-level speculation provides a way to parallelize sequential programs without the n...

Improving memory hierarchy performance for irregular applications
The performance of irregular applications on modern computer systems is hurt by the wide gap between CPU and memory speeds because these applications typically underutilize multi-...

Application scaling under shared virtual memory on a cluster of SMPs
In this paper we examine how application performance scales on a state-of-the-art shared virtual memory (SVM) system on a cluster with 64 processors, comprising 4-way SMPs connect...

An experimental evaluation of tiling and shackling for memory hierarchy management
On modern computers, the performance of programs is often limited by memory latency rather than by processor cycle time. To reduce the impact of memory latency, the restructuring ...

Symmetry and performance in consistency protocols
A consistency protocol can be termed symmetric if all processors are treated identically when they access common resources. By contrast, asymmetric protocols usually assign a home...
