Using cache optimizing compiler for managing software cache ondistributed shared memory system

摘要

On a distributed shared memory (DSM) system, the optimization ofmemory access is very important for achieving good performance. Theauthors propose an optimizing compiler which controls a software cachesystem implemented on a DSM. The software cache consists of a staticpart related to the compiler and a dynamic part related tocache-managing runtime routines. The compiler controls the static partof the software cache by using information from static analysis. Forapplications whose behavior can only be dynamically determined, thecompiler uses the dynamic part of the software cache. They also proposethe application of RISC-oriented optimization techniques to parallelapplications on their software cache system. They evaluate theefficiency of the compiler and RISC-oriented optimization techniques onthe CM-5 distributed parallel machine. The results show that thecompiler and the optimizations considerably improve the performance ofbasic linear algebra routines: matrix multiplication, Choleskydecomposition and Gaussian elimination
