In some programming contests, problems have a memory limit (like 64MB or 256MB). How can I understand the memory used by my program (written in C++) with bash commands? Is there any way to limit the memory used by the program? The program should terminate if it uses more memory than the limit.
The command top will give you a list of all running processes and the current memory and swap or if you prefer the GUI you can use the System Monitor Application.
As for locking down memory usage you can always use the ulimit -v to set the maximum virtual address range for a process. This will cause malloc and its buddies to fail if they try to get more memory than that set limit.
