ThreadPinning.likwidpin_domains — Method

likwidpin_domains(; onebased)

The likwid-pin compatible domains that are available for the system.

source

ThreadPinning.likwidpin_to_cpuids — Method

likwidpin_to_cpuids(lpstr; onebased)

Convert the given likwid-pin compatible string into a CPU ID list. See pinthreads_likwidpin for more information.

source

ThreadPinning.pinthreads_likwidpin — Method

pinthreads_likwidpin(str; onebased)

Pins Julia threads to CPU-threads based on the given likwid-pin compatible string. Checkout the LIKWID documentation for more information.

If the keyword argument onebased is set to true, logical indices as well as domain indices start at one instead of zero (likwid-pin default). Note, though, that this doesn't affect the explicit pinning mode where "physical" CPU IDs always start at zero.

Examples

pinthreads_likwidpin("S0:0-3")
pinthreads_likwidpin("M1:0,2,4")
pinthreads_likwidpin("S:scatter")
pinthreads_likwidpin("E:N:4:1:2")
