Arguments

Type IntentOptional Attributes Name
type(Matrix_lsr), intent(in) :: matrix

The matrix to send.
integer, intent(inout) :: comm

The communicator to send along.
type(Matrix_lsr), intent(inout) :: gathered_matrix

The matrix we are gathering.

private subroutine ReduceAndComposeMatrix_lsc(matrix, comm, gathered_matrix)

Arguments

Type IntentOptional Attributes Name
type(Matrix_lsc), intent(in) :: matrix

The matrix to send.
integer, intent(inout) :: comm

The communicator to send along.
type(Matrix_lsc), intent(inout) :: gathered_matrix
