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

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?
