Your program still has a 32-bit address space, out of which the kernel takes approximately 1 bit (Linux grants 1GB, 2GB or 3GB to userspace depending on compilation options). If you ...

pae stand for physical address extension and allow a cpu with a 32bit address bus to address more than 4G. Notice that if your /proc/cpuinfo show support for pae isn't enough, you need to use a kernel compiled with pae options enabled (eg: I'm using a Debian prebuilt 3.16-2-686-pae) The memory model/layout of a Linux process is defined by the Linux kernel ...

The setrlimit(2) syscall is relevant to limit resources (CPU time -integral number of seconds, so at least 1 sec- with RLIMIT_CPU, file size with RLIMIT_FSIZE, address space with RLIMIT_AS, etc...). You could also set up disk quotas. The wait4(2) syscall tells you -and gives feedback- about some resource usage. And proc(5) tells you a lot more, and also ...
