I want to use the machine to do finite element analysis & want to be able to address as much of the 4 GB 32 bit address space as possible to run big jobs (I was stuck at 2 GB w/ Linux, that's why FreeBSD). I have talked w/ some people who gave me some suggestions, but most were for 4.5, not 4.4. I can use 2 GB now, but whenever I recompile the kernel w/ larger MAXDSIZ parameter (larger than 2 GB), the compile & install go OK, but the kernel won't boot. Someone said something about trying to cut down on a parameter called KVA_PAGES, but that's 4.5, not 4.4. What is the equivalent parameters(s) under 4.4 ? Thanks in advance for your time.
