The CUDA component is a hardware performance counter measurement technology for the NVIDIA CUDA platform which provides access to the hardware counters inside the GPU. PAPI CUDA is based on CUPTI support - shipped with CUDA 4.0rc - in the NVIDIA driver library. In any environment where the CUPTI-enabled driver is installed, the PAPI CUDA component can provide detailed performance counter information regarding the execution of GPU kernels.
