Abstract

The invention discloses a nonvolatile memory bandwidth detection method. The method comprises the following steps: setting a nonvolatile memory to be in an APD mode; creating a namespace in the APD mode, and formatting the namespace into an EXT4 format; reading / writing the bandwidth of all the namespaces through each CPU by utilizing a tool for testing memory delay and bandwidth; and collecting and arranging the data of the CPU read / write bandwidth, and evaluating the nonvolatile memory bandwidth performance based on the data. The invention further discloses a nonvolatile memory bandwidth detection device, computer equipment and a readable storage medium. According to the method, the bandwidth performance of the nonvolatile memory is tested in the hard disk mode of the nonvolatile memory by using a tool for testing the memory delay and the bandwidth, so that errors caused by single-mode testing are avoided, the tested data is more complete and accurate, and more data support is provided for performance evaluation of the nonvolatile memory.

Description

technical field [0001] The technical field of server testing of the present invention relates in particular to a non-volatile memory bandwidth detection method, device, equipment and readable medium. Background technique [0002] The operation modes of non-volatile memory are mainly divided into three types: Memory mode, APD mode and Mix mode. Among them, the APD mode is divided into two types: interleaved and not-interleaved. When it is in Memory mode, it is similar to ordinary memory, it has the function of memory and can be used as memory; when it is in APD mode, it has the function of storage and can be used as hard disk; when it is in mixed mode, it has the function of memory and hard disk at the same time . [0003] The Whitley platform is a platform that can support the operation and use of non-volatile memory on it. It can verify the performance and functions of non-volatile memory and make full use of its excellent characteristics. For memory-intensive workloads,...
