As I understand it, this is an Intel `clone' of AMD64, so the only news would be if there were any problems: in almost all cases the executable code is identical to that compiled for AMD64 and in the GNU classification it is also "x86_64-unknown-linux-gnu". I would even expect a Goto BLAS to work, if not as well as on the specific Opteron it is tuned for. (Fast BLASes are an essential part of making the most of 64-bit processors on large problems.) > Michael Seewald wrote: > > Dear mailing-list members, > > > > In the days of cheap RAM and microarray applications feasting on memory, > > 64-bit computers become more and more useful - to actually make use of memory > > beyond the magic 4GB border.
