Date: 2 Oct 1992 01:30:40 -0700 Organization: University of Southern California, Los Angeles, CA Lines: 30 Distribution: inet Message-ID: <1ah1bgINNk0b@neuro.usc.edu> NNTP-Posting-Host: neuro.usc.edu Do I understand correctly that the maximum user process size available in SCO UNIX SYSV/386 is 4 MB (MAXUMEM=8,192 pages * 512 bytes/page)??? Is this limitation specific to SCO UNIX or is it generic to AT&T UNIX? Can I get around this limitation by running under root, odt, whatever? This is creating a serious problem for me as I move into working with larger and larger 3D models of human brain structure and activity. Does any other 386 based UNIX (or at least 386based system capable of supporting AT&T and/or BSD compatible unix source code with minimal conversion effort) offer larger user process (individual task) virtual address space? Perhaps BSD/386, 386BSD-0.1, coherent, solaris, linux, MSDOS w/DJGCC, MS WINDOWS w/32 Bit Zortech C++, OS/2 2.0, ? Ideally, I'd like to be able to go up to perhaps 64MB virtual address space on 64MB 486 based EISA motherboard.
