摘要

本文研究了Intel Itanium2处理器和矢量处理器的性能相似性。从对最新标量处理器的矢量计算的测量来看，Itanium2与VPP5000在性能上有相似的优点和缺点。对于密集矩阵的乘法，Itanium2和VPP5000表现出相对较高的持续性能，达到理论峰值。另一方面，对于稀疏矩阵的矩阵向量乘法，这两种处理器表现出较差的性能。

Performance comparison of vector-calculations between Itanium2 and other processors

This paper examines the performance similarity of the Intel Itanium2 processor and a vector processor. From the measurements of vector-calculations on latest scalar processors, Itanium2 shares similar strong points and weak points of performance with VPP5000. For multiplications of dense matrices, Itanium2 and VPP5000 show relatively high sustained-performance to the theoretical peak. For matrix-vector multiplications with sparse matrices, on the other hand, those two processors show poor performance.
