◆ ncclRedOp_dummy_t

enum ncclRedOp_dummy_t

Dummy reduction enumeration.

Dummy reduction enumeration used to determine value for ncclMaxRedOp

    ncclNumOps_dummy = 5
} ncclRedOp_dummy_t;

◆ ncclRedOp_t

enum ncclRedOp_t

Reduction operation selector.

Enumeration used to specify the various reduction operations ncclNumOps is the number of built-in ncclRedOp_t values and serves as the least possible value for dynamic ncclRedOp_t values constructed by ncclRedOpCreate functions.

ncclMaxRedOp is the largest valid value for ncclRedOp_t and is defined to be the largest signed value (since compilers are permitted to use signed enums) that won't grow sizeof(ncclRedOp_t) when compared to previous RCCL versions to maintain ABI compatibility.

Enumerator
ncclSum	Sum
ncclProd	Product
ncclMax	Max
ncclMin	Min
ncclAvg	Average
ncclNumOps	Number of built-in reduction ops
ncclMaxRedOp	Largest value for ncclRedOp_t
