NAME

       prefetch - Prefetch bytes into the global cache.

       void prefetch(const __global gentype *p, size_t num_gentypes);

DESCRIPTION

       Prefetch num_gentypes * sizeof(gentype) bytes into the global cache. The prefetch
       instruction is applied to a work-item in a work-group and does not affect the functional
       behavior of the kernel.

NOTES

       The generic type name gentype indicates the built-in data types char, char{2|3|4|8|16},
       uchar, uchar{2|3|4|8|16}, short, short{2|3|4|8|16}, ushort, ushort{2|3|4|8|16}, int,
       int{2|3|4|8|16}, uint, uint{2|3|4|8|16}, long, long{2|3|4|8|16}, ulong, ulong{2|3|4|8|16},
       float, float{2|3|4|8|16}, or double, double{2|3|4|8|16} as the type for the arguments
