We have a python script in /home/aifs2/group/code/limitWrapper that constrains the memory usage or time limit of a executable command. It uses /proc/[PID]/smaps to read the memory usage of your program. See details of smaps here.

./limitWrapper.py -h                                                                                                                                 

usage: ./limitWrapper.py [-h] [-c COMMAND] [-m MEMORY] [-t TIME]

optional arguments:

  -h, --help  show this help message and exit

  -c COMMAND  command: (default) ls ~

  -m MEMORY   memory limit:(default) 5 (GB)

  -t TIME     time limit:(default) 600 (seconds)

example:

./limitWrapper -c "/home/aifsx/xxx/bin/search" -m 7 -t 10

will run command /home/aifsx/xxx/bin/search with memory limit 7GB and time limit 10 seconds. 

It uses a lot of function from DistLRE
