hipFile documentation

hipFile is AMD’s Infinity Storage library that provides direct-to-GPU I/O without requiring a host-side buffer. The library provides C and Python APIs for synchronous, asynchronous, and batch I/O operations. hipFile automatically falls back to POSIX I/O when operations are unable to use the direct-to-GPU path.

hipFile is delivered as part of TheRock. The hipFile source code is located at ROCm/rocm-systems.
