  3. ply_fpt_init

public subroutine ply_fpt_init(n, params, trafo, blocksize, approx_terms, striplen, subblockingWidth)

Arguments

TypeIntentOptionalAttributesName
integer, intent(in) :: n
type(ply_trafo_params_type), intent(inout) :: params
integer, intent(in) :: trafo
integer, intent(in), optional :: blocksize

Smallest block that is approximated by approx_terms coefficients.

Please note, that this has to be larger than 2*approx_terms to result in a reduced number of operations. Default is 64.
integer, intent(in), optional :: approx_terms

Number of approximation terms used to compute off-diagonal products.

Defaults to 18, which is the suggested accuracy for double precision.
integer, intent(in) :: striplen

Length to use in vectorization, this is the number of independent matrix multiplications that are to be done simultaneously.
integer, intent(in), optional :: subblockingWidth

The width of the subblocks used during the unrolled base exchange to ensure a better cache usage.
