I had a bit of a peek around the archives, wow, I guess hppa64 isn't the most 'comfortable' place for a g++ developer just now. > This is not to say it couldn't be done of course.

A computational physics code. Ideally I would run it in 100s of GB of RAM. About two months of pain went into making it work (reasonably efficiently, in theory at least) in 100s of GB of swap. Now you have *me* curious; I don't mean to be an ignorant asshole, but what's the point of hppa64 if you *don't* support >4G address space? *crying* does HP-UX support >4G address space? *finds wallet* :( Hmm, probably have to shell out more $$$ for the HP compilers too :\ Duraid
