Options (20)
| Option | Description | Source |
|---|
-a | List all processes, even those that are not bound to any specific part of the machine. | help + man |
--pid pid | Only show process of PID <pid>, even if it is not bound to any specific part of the machine. | help + man |
--name name | Only show processes whose name contains <name>, even if they are not bound to any specific part of the machine. | help + man |
--uid uid | Only show processes of the user whose UID is <uid>, or processes of all users if all is given. | help + man |
-l --logical | Report logical indexes instead of physical/OS indexes (default) | help + man |
-p --physical | Report OS/physical indexes instead of logical indexes | help + man |
-c --cpuset | Show process bindings as cpusets instead of objects. | help + man |
--single-ancestor | When the object is bound to different objects, report their common ancestor (even if it may be larger than the actual binding). | help + man |
-t --threads | Show threads inside processes. | help + man |
-e --get-last-cpu-location | Report the last processors where the process/thread ran. | help + man |
--pid-cmd cmd | Append the output of the given command to each PID line. | help + man |
--short-name | Show only the process short name instead of the path. | help + man |
--disallowed | Include objects disallowed by administrative limitations. | help + man |
--lstopo-misc file | Output a file that may be given to lstopo --misc-from for displaying processes/threads as Misc objects. | help + man |
--json-server | Run the tool as a JSON server that waits for other process' requests on a port and sends back binding information. | help + man |
--json-port n | Use the given port number instead of the default 8888. | help + man |
-v --verbose | Increase verbosity of the JSON server. | help + man |
--version | Report version and exit. | help + man |
-h --help | Display help message and exit. | help + man |
--children-of-pid pid | Only show process of PID <pid> and its hierarchy of children, even if they are not bound to any specific part of the machine. (in the manual page but not in --help) | man |
Examples (5) from the manual page, untested
hwloc-ps
4759 Core:0 myprogram
If a process is bound, it appears in the default output:hwloc-ps
4863 Core:1 Core:2 myprogram
$ hwloc-ps --single-ancestor
4863 Package:0 myprogram
If a process is bound on two cores of a larger package, the output will show these cores.hwloc-ps
If a process is not bound but 3 of his 4 threads are bound, it only appears in the thread-aware output (or if explicitly selected):hwloc-ps -t
