libxsmm_hash Interface

public interface libxsmm_hash

Calculate a hash value for a given key value (binary blob). Conceptually pure, but C_LOC may be (incorrectly) impure.


Module Procedures

public function libxsmm_hash_char(key, seed)

Calculates a hash value for the given array and seed. FORTRAN 77: see libxsmm_xhash

Arguments

Type IntentOptional Attributes Name
character(len=C_CHAR), INTENT(IN)$CONTIGUOUS :: key(:)
integer(kind=C_INT), intent(in) :: seed

Return Value integer(kind=C_INT)

public function libxsmm_hash_i8(key, seed)

Calculates a hash value for the given array and seed. FORTRAN 77: see libxsmm_xhash

Arguments
