If the node has no processors, the node is not shown. ![]() minimal example for win Im not aware of any framework that is crossplatform for this kind of information - mostly because theres just no way to get this information without delving deep into the platforms insides. Processors - a list of processors in this node. On linux you can do something similar by parsing information out of proc/cpuinfo and other stuff (not an expert there).Table shows the following information about NUMA nodes: Microprocessor feature flags indicate what features the microprocessor supports. From the cpuinfo file, I want to return the cpu Mhz and model name. Microprocessor signature hexadecimal fields (Intel platform notation) show signature values: 1 I am trying to write a script that will return info from the /proc/cpuinfo, /proc/meminfo and /proc/version files. A logical cpu can be a hyperthreading sibling. Processors - a list of processor groups enclosed in the parentheses those share this cache or no sharing otherwise. The kernel data Linux exposes in /proc/cpuinfo will show each logical cpu with a unique processor number.A group of processors enclosed in brackets belongs to one core.Ĭache sharing by logical processors shows information of sizes and processors groups, which share particular cache level. This list order directly corresponds to the core list. Processors Id - list of processors that belong to this package.Cores Id - list of core identifiers that belong to this package.Package Id - physical package identifier.Each entry contains the information on packages, cores, and logical processors. Node decomposition table shows the node contents. Package Id - unique package identifier within a node.Core Id - unique core identifier within a package.Thread Id - unique processor identifier within a core.Logical processors identification table identifies threads, cores, and packages of each logical processor accordingly. core and threads numbers on the node and within each package. ![]() the number of packages/sockets on the node.General information about single cluster node shows: Each option controls a specific part of the output data.
