Stream system limit throughput performance evaluation method and system

Abstract

The invention discloses a Stream system limit throughput performance evaluation method and system, and the method comprises the steps of determining a memory read operation throughput value and a memory write operation throughput value, determining a memory performance evaluation mode corresponding to an access operation, and determining a first relation matched with the memory performance evaluation mode based on the memory performance evaluation mode, wherein the first relationship is the relationship between the memory performance limit throughput value and the memory read operation throughput value and the memory write operation throughput value; and determining the memory performance limit throughput value based on the first relationship, the memory read operation throughput value and the memory write operation throughput value. According to the scheme, the memory read operation throughput value and the memory write operation throughput value are respectively determined, and the limit throughput performance of each memory performance evaluation mode is determined based on the memory read operation throughput value and the memory write operation throughput value; the limit throughput performance of the system is analyzed and determined based on the independent memory read operation and the independent memory write operation, so that system optimization based on the limit throughput performance is facilitated.

Description

Technical field [0001] The present application relates to the field of electronic information technology, and more particularly to a STREAM system limit throughput performance assessment method and system. Background technique [0002] On the general CPU platform such as ARM, memory read and write throughput (MB / S) is one of the main performance indicators of the whole machine or CPU. [0003] The current memory assessment tool and algorithm currently applied in high performance CPU are the Stream program and software tools proposed and involved in the University of Virginia University, and as long as the idea algorithm is used in C-language or other advanced programming languages. Continuous virtual memory. (Generally 512MB or more) multiple read and write, get the time each full read and write, take the fastest execution, and then calculate the throughput according to the amount of data and execution time. [0004] When the memory performance evaluation is performed via the S...

But no matter which of the above algorithms is used, the amount of data involved is the total amount of data including both reading memory and writing memory. If the time consumed by reading memory and writing memory cannot be determined, it is impossible to determine the system The limit data volume, that is, the limit throughput performance of the Stream system cannot be determined
