OxiCUDA 0.5.3 Released — Closing an Async-Copy Race in FFT Transforms and DeviceBuffer
OxiCUDA 0.5.3 fixes an async-copy race condition where cuMemcpyDtoHAsync/cuMemcpyHtoDAsync and DeviceBuffer::copy_from_host could return before the transfer had actually landed, letting the very next read observe stale or zeroed device/host memory. 38,675 tests, ~1.30M SLoC, 74 crates.
