For our BLAS variant of the similarity-join, we use the matrix multiplication provided by BLAS and the Euclidean distance by scalar product (see paper).

The individual blocksize needs to be experimental evaluated for each individual hardware. Our selfjoin variant, only iterates over the lower triangle of the similarity matrix.
