Yes, you will have to tweak a few kernel values to allow more than 512M per process. And then have enough core RAM and swap to back your data. > Other question: If I have less memory than 3G, is it possible to put > the limit to 3G (~2.9 G, I need to check again the posts about this > limit) whith swaping of course. Consider leaving the data on disk and simplify your problem. > May be I should buy a 64bits computer ... Back in the days of 8 bit computers people manipulated data greater than 64k, so with a bit of thinking and planning you should be able to do similar. -- David Kelly N4HHE, dkelly@HiWAAY.net ======================================================================== Whom computers would destroy, they must first drive mad.
