Hello isis-fish developper. I was on phone with AMD, and they were explaining to me that java can run in GPGPU architecture. which means that you can run your java code not only using your CPU but graphical processor part of a computer. http://developer.amd.com/resources/java-zone/ did you know that? are you interested? As we'll move from machine caparmor to machine datarmor, I would like to know if you are interested in such optimisation in future or not, regards, Tina -- =================================================== Tina Odaka RIC - IDM - IMN - IFREMER Pôle de Calcul Intensif pour la Mer (PCIM) Tel: +33 (0)2 98 22 41 85 Fax: +33 (0)2 98 22 45 46 email: Tina.Odaka@ifremer.fr http://www.ifremer.fr/pcim ==================================================
