baracuda-cufile-sys

Raw FFI bindings + dynamic loader for NVIDIA cuFile — the GPUDirect Storage user-space library, enabling direct DMA between NVMe / network storage and GPU memory without bouncing through host RAM.

Symbols resolve lazily via libloading; no link-time dependency on libcufile.so.

Most users want baracuda-cufile — that crate exposes typed driver-lifecycle / file-handle / buffer-registration / read-write / batch-IO APIs in idiomatic Rust.

Platform support

cuFile / GPUDirect Storage is Linux-only. The loader fails fast with a clear error on Windows / macOS.

What's exposed

• Driver lifecycle: cuFileDriverOpen, cuFileDriverClose, cuFileDriverGetProperties, cuFileDriverSetPollMode etc.
• File-handle register / deregister.
• Buffer register / deregister (for both pinned and managed memory).
• Sync read / write: cuFileRead, cuFileWrite.
• Async read / write on a stream.
• BatchIO: setup, submit, poll, cancel, destroy.
• Configurable direct-I/O / cache / pinned-mem limits.
