Hello, Do you have any experience of using NONMEM installed on one or several Windows 2008 servers (ex: windows 2008 R2 Octo processor)? A comparaison of Windows 2008 versus Linux grid architecture would be welcome. Thank you very much for your feedback, Marylore ________________________________ Marylore CHENEL, PharmD, PhD Director of Clinical Pharmacokinetics Institut de Recherches Internationales Servier 6 Place des Pléiades F-92415 Courbevoie Cedex Tel: +33 155 72 38 56 / Cell:+33 670 07 25 36 Fax: +33 155 72 37 26 E-mail: marylore.che...@fr.netgrs.com
