Description
Since PARI 2.15, the computation of the rank of rational elliptic curves is available in the ellrank function. It is supposedly much faster than what is available in Denis Simon script that sage is using.
Though, the output is not compatible: pari returns a quadruple [r, s, XXX, v] where Denis Simon version returns a triple [r, s, v].The XXX is related to the Tate-Shafarevich group.
