[email protected] changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #1 from [email protected] --- It seems like PARTIAL_RAT_STALLS.SLOW_LEA_WINDOW and PARTIAL_RAT_STALLS.MUL_SINGLE_UOP related to Sandybridge CPUs. Since I don't have real hardware I tried it in VM: root@bsd:/home/tsgan/himenobmtxpa/src # cpuset -l 0 pmcstat -w 1 -p CPU_CLK_UNHALTED_CORE -p PARTIAL_RAT_STALLS.SLOW_LEA_WINDOW -p PARTIAL_RAT_STALLS.MUL_SINGLE_UOP ./himenobmtxpa M 384 For example: Grid-size= XS (32x32x64) S (64x64x128) M (128x128x256) L (256x256x512) XL (512x512x1024) Grid-size = # p/CPU_CLK_UNHALTED_CORE p/PARTIAL_RAT_STALLS.SLOW_LEA_WINDOW p/PARTIAL_RAT_STALLS.MUL_SINGLE_UOP 3026657 17021 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 ... Not sure whether my setup is correct or not, but I don't see such big numbers. How many and what type of CPUs do you have? What else is running on your system? How can I test it in Xeon system? -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
