Installing Dependencies MindCluster ToolBox is a system-level toolset for cluster operations and hardware management, mainly used for operations such as device monitoring, performance testing, and log collection. MindCluster ToolBox includes the Ascend DMI tool, the log collection tool, and the Ascend Cert tool. MindCluster ToolBox works by calling low-level DCMI (Device Control Management Interface) and AscendCL (Ascend Computing Language) interfaces to perform the relevant detection functions; system-level information queries are implemented by calling the general-purpose libraries provided by the system.微信公众号AIDMIAscendHuaweiNPUTroubleshootingPerformance Testinghttps://www.chenshaowen.com/en/blog/ascend-environment-variable-configuration.htmlMon, 20 Jan 2025 00:00:00 +0000Mon, 20 Jan 2025 00:00:00 +0000https://www.chenshaowen.com/en/blog/ascend-environment-variable-configuration.htmlHCCL_IF_IP Configures the IP of the root communication NIC for HCCL initialization.
