SpeedIT is a set of GPU- accelerated iterative solvers for solving a system of linear equations. It has been performance - tested on more than 20 matrices from the Florida Matrix Collection and provides mainfold acceleration over traditional methods. Its performance rates between 2.1 and 11 GFLOPs in double precision mode. We present a visualisation of the blood flow in a human aorta (in collaboration with IT'IS Foundation, Zurich, Switzerland).
