Our implementation of MM benchmark

See MatrixMultiply.

Introduction

We have tested the ACML-GPU version 1.1. We used Cypress GPU running at 850MHz for our tests. The operationt system we adopted is Ubuntu 10.4 LTS. Note we presented two lines for each plot below. One is the result obtained with X58 chipset and other with X38 chipset. PCI transfer speed of Cypress with X58 chipset shows rather limited performance of roughly 600 MB/sec for GPU to CPU. X38 chips shows reasonable speed of > 6 GB/sec for large data. However, it seems that the transfer speed is not critical for GEMM benchmark.
