Using VTune to analyze CESM with Offloading on Xeon Phi

[Amlesh_K_]

Hi all,

I have offloaded a function in CAM model of CESM to the Intel Xeon Phi and trying to optimize it further. How can I use Intel Vtune AXE to profile CESM which has an offloaded function on Xeon phi?

Thanks

Hello Amlesh,

In command line you need to use the folllwing syntax (on the example of advanced-hotspots analysis type):

>amplxe-cl -target-system=mic-host-launch -collect advanced-hotspots ./my_app_on_host

For GUI you need to choose the following analysis target:

and provide host application as application to launch.

You can also find more details in VTune help here.

Please note that in the VTune result you will have only collection from Xeon Phi target. We don't provide mixed host/card collection in one result.

Thanks & Regards, Dmitry
