- W4310584054 abstract "The general matrix-vector multiplication (GEMV) is one of the most critical operations in HPC (high performance computing) researches and engineering applications, and is often used to evaluate the performance of a new architectural system. As the scale of the GEMV problem continues to expand, frequent out-of-order access to the DRAM gradually leads to the decrease of the system access bandwidth, which becomes the bottleneck to solve the GEMV efficiently. In this paper, we propose a high bandwidth cache designed in a highly customized memory controller and an efficient cache major scheduling policy which fully utilize DRAM address locality to achieve high-performance GEMV computation. The experimental results show that our proposed cache-major policy has reached a single-core sustained effective bandwidth of 112.34 MB/s (@2000× 2000, 32-bit float-point matrix), much better than baseline design and existing mature works." @default.
