Possibility of getting hardware counters at regular intervals #8

Closed trinayan closed 7 years ago

trinayan commented 7 years ago

I am working on a research project that requires me to have access to the counters at regular intervals instead of at the end of an application. Is it possible to use this tool?

Hi Trinayan,

GPA allows you to bracket GPU workloads in order to collect performance counters for an individual workload. A workload can be one or more draw calls or a dispatch. You should be able to use GPA to sample different workloads while your application is running. However, if you are talking about time-based sampling a particular workload (i.e. you want to see how a particular counter value changes while a single dispatch is running), that is not currently supported.

Ok thanks a lot for the information

Is there any example on how to use gpuperf with a opencl application. ?
