We would like to announce that the PAPI CUDA component is now available from the PAPI cvs repository. 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. If users want to test the component, they will have to do a clean checkout from cvs. Also, we are planning on releasing PAPI 4.2 when NVIDIA has a stable CUDA release in case you want to wait for an official release.
Let us know if you have questions.
