Required performance counter for selecting best Hyper-Threading(HT) mode in Intel Xeon Phi.

[parthsl]

The algorithm here gives best result with SMT-4 mode in POWER-8 as shown in below image. This is reflected in front-end-stall-cycles from perf tool being the least for SMT-4 mode.

The same is found for Intel indicating HT-2 mode is the best for the proposed algorithm by showing least execution time among all modes.

The Intel Xeon Phi doesn't support front-end stall cycles counter. So is there any performance counter in Intel Xeon Phi-2(Knights Landing) architecture which can indicate HT-2 is the best in the given case? Or is there any other way to prove HT-2 is the best?
