Occupancy and latency profilers broken on Ivy Bridge

Lorenzo_P_ · ‎11-05-2015

Version 2015.2.027.

Occupancy gives nonsensical data:

latency crashes, probably because it tries to use svm which is not available in OpenCL 1.2:

THREAD NOT JOINABLE, PROBABLY CRASHED
ERROR (from lib-gtpin): [ERROR] FillMyFunctionMap() couldn't find clSetKernelArg SVMPointer

So basically none of the profilers works for me, alright.

Lorenzo,

Unfortunately, this is a known problem on Ivy Bridge machines (3rd gen processor graphics). Make sure you have the latest and greatest driver from here https://downloadcenter.intel.com/download/25313/Intel-HD-Graphics-Driver-for-Windows-7-8-1-10-3rd-Gen-BYT- and you may want to try an evaluation version of Intel® VTune™ Amplifier 2016 (see here https://software.intel.com/en-us/intel-vtune-amplifier-xe/).
