# mx-qual用户手册 ## 概述 本文档介绍了 `mx-qual`(MOFFETT QUALIFICATION )工具的使用方法。`mx-qual` 是基于 `SOLA Runtime API` 实现的设备质量测试工具,主要用于检测设备的可用性、稳定性、性能等方面的指标。 ## 使用方法 `mx-qual` 是一个命令行工具,可以通过 `mx-qual -h` 查看帮助信息。 ```shell Moffett Quality Inspection Application v1.2.0 Usage: mx-qual [OPTIONS] SUBCOMMAND Options: -h,--help Print this help message and exit --version Display program version information and exit Subcommands: list List all devices detected on the system hardware_link Run hardware link test pcie_bandwidth Run PCIe bandwidth test memory_bandwidth Run memory bandwidth test p2p Run peer to peer test compute Run computing power test stress Run stress test memtest Run hardware memory test ``` `mx-qual` 以子命令的方式去执行相应的测试,子命令的使用方法可以通过 `mx-qual -h` 查看。 ### 子命令说明 #### list ```text List devices Usage: mx-qual list [OPTIONS] Options: -h,--help Print this help message and exit -i,--index UINT:INT in [0 - 31] ...
