GPUDirect Storage#
GPUDirect Storage (GDS) enables a direct data path for direct memory access (DMA) transfers between GPU memory and storage, which avoids a bounce buffer through the CPU. This direct path increases system bandwidth and decreases the latency and utilization load on the CPU.
cuFile - Core GDS and file system client APIs
cuObject - Object APIs for client and server
This documentation is organized into two main sections. cuFile provides the core GPUDirect Storage documentation, including usage guides, API reference, configuration, troubleshooting, and best practices for using GPUDirect Storage with local and distributed file systems. cuObject provides the client and server API specifications for use with object storage solutions, along with release notes for cuObject components.
