Module memory_info 

GPU memory usage queries and unified memory hints.

This module provides:

• MemoryInfo and memory_info for querying free/total GPU memory.
• MemAdvice and mem_advise for providing memory usage hints to the CUDA unified memory subsystem.
• mem_prefetch for prefetching unified memory to a specific device.

Example

let info = memory_info()?;
println!("GPU memory: {} MB free / {} MB total",
    info.free / (1024 * 1024),
    info.total / (1024 * 1024),
);

Structs

MemoryInfo

GPU memory usage information.

Enums

MemAdvice

Memory advice hints for unified (managed) memory.

Functions

mem_advise

Provides a memory usage hint for a unified memory region.

mem_prefetch

Prefetches unified memory to the specified device.

memory_info

Queries free and total device memory for the current CUDA context.
