I can't find a direct answer for these two linked questions, hence the query to this email address. We're looking into FreeBSD running on Athlon64 processors to give us the ability to handle seriously huge datasets. We did buy a G5 machine, but their implementation of BSD seems still only able to malloc() up to a 4Gb process limit which is hardly what their advertising says! Therefore, does the AMD64 FreeBSD port allow you to malloc() or mmap() past this 4Gb per process limit. We're typically wanting to address up to 256Gb in a single process. Thanks in advance for any light you can shed on this. Regards, A.
