In a context with: # cpuset -g pid -1 mask: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, = 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27 pid -1 domain policy: first-touch mask: 0, 1 I get: # cpuset -l0 -n prefer:0 COMMAND cpuset: setdomain: Invalid argument # cpuset -l0 -n prefer:2 COMMAND cpuset: setdomain: Invalid argument But one prefer:? value does allow the COMMAND to run: # cpuset -l0 -n prefer:1 COMMAND This seem odd to me. Am I missing something? For reference: I'm using a ThreadRipper 1950X with a head -r351227 based context for this activity. The above happens to have been run in a Windows 10 Pro HyperV session, instead of in a native-boot of the same media. (A native-boot would have had 32 CPUs.) =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
