From 9c67d3883adaa8a65e3567579cf99937deaab21a Mon Sep 17 00:00:00 2001 From: Giorgio Arena Date: Fri, 20 Aug 2021 15:24:03 +0100 Subject: Remove map/unmap overhead for input/output accessor when using DummyAccessor Don't map/unmap when the tensor data is not accessed in the input or output accessor. This is so to avoid measuring CPU overhead when benchmarking on the GPU backend.
