That means as I have 200 processes running like my laptop on Solaris 11, I would need more than 800 GB of RAM+swap area.
I thought OS don't allocate any swap area nor physical memory to a new got virtual space, but allocate physical pages directly when this space is written/read, and swap out when done some thing.Do you mean, OS allocate swap area to a process when it use malloc to ask for memory, but swap it into physical memory when this space is written/read?
I've written a test program that ask for nearly 3GB by sbrk() on my Archlinux that only have 128M RAM and 40M swap partition. But when I use the 'free' command , I see it does'nt take any swap space.
