 The KNL  has two memory systems, the DDR4 (~90 GFlops/s) and the High Bandwidth Memory (MCDRAM, ~400 Gflops/s).

+### Using the optimised Wilson Dslash kernels
+
+Beside the generic implementation using stencils, GRID has optimised version of the Dslash kernels (for Wilson and DWF fermions). 
+
+Flags at runtime can be used for the optimised paths

+| `--dslash-unroll`   	| This explicitly unroll the colour loops. It is tied to `Nc=3`        	|
+| `--dslash-asm`      	| This is specific for AVX512-F architectures and `Nc=3`               	|
