Hence the "out of > place" questions. AIX is definitely more of a circus than, say, Linux. I'd not be surprised if it becomes a worthwhile idea in the not too distant future to look at running Linux on the higher end pSeries hardware instead of AIX. I'm certain that would make most of the challenges go away. IBM would be keen to sell pSeries hardware running Linux, too; the drawback at this point is that it's not clear that the more esoteric high performance hardware will work with Linux yet. They don't have HACMP for Linux yet, for instance, and support for high end disk controllers and such may yet be limited. > I'll examine threadsafety, compiler options, and hetergeneous > compiler/build enviroments. We'll be looking at some of the same fairly shortly, as we're receiving some AIX 5.3 systems. As issues come, that will no doubt feed back somewhat to the FAQ_AIX document. One thing worth checking on... Are you a VisualAge C user? Or do you wind up using GCC? We're using GCC, which definitely plays a little different than VAC... -- "cbbrowne","@","gmail.com" http://cbbrowne.com/info/lsf.html "Problem solving under linux has never been the circus that it is under AIX." -- Pete Ehlke in comp.unix.aix "Whip me.
