Name
gpfsClearFileCache_t - Indicates file access in the near future is not expected.
Structure
typedef struct
{
int structLen;
int structType;
} gpfsClearFileCache_t;
Description
The application does not expect to make any further accesses to the file in the near future, so GPFS removes any data or metadata pertaining to the file from its cache.
Multi-node applications that have finished one phase of their computation may wish to use this hint before the file is accessed in a conflicting mode from another node in a later phase. The potential performance benefit is that GPFS can avoid later synchronous cache consistency operations.
