Hello, we have also done some tests on AIX, however not systematically. Our experience is, that performance on AIX is bad, the reasons are not really clear to me, but e.g. the linear algebra routines which are parallelized even in version 6 and use specific processor dependent libraries, just do not seem to work efficiently on AIX. I have a program which works for several days on a supposedly very powerful AIX but finishes within a day on a simple Linux server. So, as a matter of fact, I have given up on AIX and only use Linux or Windows systems for now. Strangely enough AIX requires a class 2 license and Linux just class 1. One of our computer specialists tried to clarify these issues with Wolfram support with little success up to now. As far as I know, Wolfram has discontinued AIX support for Version 7 anyway, so it seems that AIX is good for business applications but not for Mathematica. Michael Weyrauch
