The TAU Performance System* (Tuning and Analysis Utilities) supports profiling and tracing of programs written using Intel oneAPI. Intel oneAPI provides two interfaces for programming: OpenCL™ software and DPC++ and SYCL* for CPUs, GPUs, and other devices. TAU has been tested on 12th generation Intel® processors now available using the Intel® oneAPI Base Toolkit and Intel® HPC Toolkit. This talk presents the advances in TAU to support oneAPI and how you can use TAU to instrument the code without any modifications to the application binary.
