-Currently the BF16 API uses the 5 loop algorithm inside the OMP loop to compute the results, irrespective if the input sizes. However it was observed that for very tiny sizes (n <= 128, m <= 36), this OMP loop and NC,MC,KC loops were turning out to be overheads. -In order to address this, a new path without OMP loop and just the NR loop over the micro-kernel is introduced for tiny inputs. This is only applied when the num threads set for GEMM is 1. -Only row major inputs are allowed to proceed with tiny GEMM.
