How to profile the communication between Host and Mic during Offload Mode

[振_徐_]

Recently I need to know exactly the data communication(exactly how much and when) between the Host and MIC while running an offload application.

Unlike Nvidia, Intel doesn't provide a tool like NV Profiler.

So I guess maybe Vtune Amplifier XE can do this job. But unfortunately I get to know that when Amplxe only analyze MIC's performance while I analyse an offload application.

So I come to get help from the forum. Is there anyone who can help me?

Setting this environment variable will cause your offload application to print detailed information about the amount of data transferred, locations of offloads in code, and timing. Unfortunately, no GUI tool for analyzing this:

export OFFLOAD_REPORT=3
