Enumeration Type Documentation

CompatMode

enum kvikio::CompatMode : uint8_t

strong

I/O compatibility mode.

Enumerator
OFF	Enforce cuFile I/O. GDS will be activated if the system requirements for cuFile are met and cuFile is properly configured. However, if the system is not suited for cuFile, I/O operations under the OFF option may error out, crash or hang.
ON	Enforce POSIX I/O.
AUTO	Try cuFile I/O first, and fall back to POSIX I/O if the system requirements for cuFile are not met.
