Abstract

Fine-grained multithreading can be used to hide long-latency operations encountered in parallel computers during remote memory access. Instead of using special processor hardware, the emulation of fine-grained multithreading on standard processor hardware is investigated. While emulation of coarse-grained multithreading is common in modern operating systems, in the fine-grained case research on emulation has been limited and design of multithreaded processors has been favored. A set of tools was developed to support emulation of multithreading on the Cray T3E parallel computer. Several experiments based on parallel matrix multiplication were performed.
