Omniperf and Omnitrace are some AMD research initiatives aimed at interpreting profile data collected by rocProf and gathering runtime performance data for software applications.

With the update of ROCm to version 5.2.3, improved profiler tools become available for GPU applications. That is because the new version of ROCm enables full access to hardware performance counters. As a result, rocProf can now collect performance counters on kernels run on AMD GPU architectures. rocProf works for HIP kernels, as well as GPU offloading OpenMP and OpenACC applications

Omniperf

There is an open source tool Omniperf which allows interpreting profile data collected by RocProf. Let's take a look at how Omniperf can be useful in the context of an example code that performs a scalar multiplication and vector addition (SAXPY).

Omnitrace

Omnitrace is an AMD research initiative aimed at gathering runtime performance data for software applications. It is compatible with programs coded in C, C++, Fortran, and Python, as well as with computational frameworks such as OpenCL and HIP. Please ensure that you load the necessary modules for Omnitrace.
