Enumeration Type Documentation

◆ cs_all_to_all_type_t

enum cs_all_to_all_type_t

All-to-all algorithm selection.

Enumerator

CS_ALL_TO_ALL_MPI_DEFAULT

Use MPI_Alltoall and MPI_Alltoallv sequences

CS_ALL_TO_ALL_CRYSTAL_ROUTER

Use crystal router algorithm

Flags are defined as a sum (bitwise or) of constants, which may include CS_ALL_TO_ALL_USE_DEST_ID, CS_ALL_TO_ALL_ORDER_BY_SRC_RANK, CS_ALL_TO_ALL_NO_REVERSE, and CS_ALL_TO_ALL_NEED_SRC_RANK.

Function Documentation

Returns: current type of all-to-all distributor algorithm choice

◆ cs_all_to_all_log_finalize()

void cs_all_to_all_log_finalize ( void )

Log performance information relative to instrumented all-to-all distribution.

◆ cs_all_to_all_set_type()

void cs_all_to_all_set_type ( cs_all_to_all_type_t t )

Set current type of all-to-all distributor algorithm choice.

Parameters

t	type of all-to-all distributor algorithm choice to select
