stablegradients/pie-gem5-pairs

PIE gem5-timed code optimization (src,tgt pairs) C++ program-optimization data derived from the PIE dataset ("Learning Performance-Improving Code Edits"), re-timed end-to-end with gem5 (x86 Skylake, syscall-emulation mode) at per-test-case granularity. One row per official (source, target) program pair. This dataset is reward-agnostic: it ships the full per-test-case reference timings and case manifests so a downstream RL / eval pipeline decides at runtime how many cases to use… See the full description on the dataset page: https://huggingface.co/datasets/stablegradients/pie-gem5-pairs.
