NVIDIA-specific TornadoVM workflows on the CUDA backend — profile with Nsight Systems (nsys) and read NVTX ranges, use the hybrid library-task API (cuBLAS/cuBLASLt/cuDNN/cuFFT/cuSPARSE/cuTENSOR/CUTLASS/NCCL native calls from Java), print the generated CUDA-C…
Run a measured performance/correctness campaign on the TornadoVM runtime — profile first (JFR for host, Nsight Systems for driver), falsify the hypothesis with a standalone probe, A/B against a same-build baseline, then ship one PR per measured claim. Use…
Build, test, and contribute to TornadoVM's OpenCL/CUDA/Metal backends — make BACKEND targets, tornado-test (quickPass/single-class), checkstyle-before-PR, one-line commits, the develop-branch PR flow, and the recurring graalJars/setvars build gotchas. Use…
