The gaussian random operator of the MKLDNN significantly speed up the resnet model. The some function of mkldnn are used directly in this operator in order to get the better performance.

• The gaussian random operator takes advantage of layout of mkldnn.
• The gaussian random directly sets the layout of mkldnn.
• Also the mkldnn format is directly forced.
• The Ohwi16o type is set to get the best performance during of reorder of weights.
