i'm currently looking for a way to handle large data set.
it seems stxxl is frequently recommended solution, however i need to know more about it, before making a decision.
the question is
Is STXXL completely platform neutral?
Any alternatives?
Any benchmarks about large data library?
1) I have personally tried it on both Windows and Linux, and there is no reason why it should not compile on Mac. I do not know what you mean by neutral though.
2) There are alternatives like TPIE, LEDA-SM etc. which are not developed anymore. I think STXXL is your best bet as it supports PDM (Parallel Disk Model).
