Just for experiment, and Fun... I am trying to create an app that can \"Purposely\" consume RAM as much as we specify immediately. e.g. I want to consume 512 MB RAM, then the ap
Here is a version of markolopa's answer that worked for me:
import os
import psutil
PROCESS = psutil.Process(os.getpid())
MEGA = 10 ** 6
MEGA_STR = ' ' * MEGA
def pmem():
try:
tot, avail, percent, used, free, active, inactive, buffers = psutil.virtual_memory()
except ValueError:
tot, avail, percent, used, free, active, inactive, buffers, cached, shared = psutil.virtual_memory()
tot, avail, used, free = tot / MEGA, avail / MEGA, used / MEGA, free / MEGA
proc = PROCESS.memory_info()[1] / MEGA
print('process = %s total = %s avail = %s used = %s free = %s percent = %s'
% (proc, tot, avail, used, free, percent))
def alloc_max_array():
i = 0
ar = []
while True:
try:
#ar.append(MEGA_STR) # no copy if reusing the same string!
ar.append(MEGA_STR + str(i))
except MemoryError:
break
i += 1
max_i = i - 1
print('maximum array allocation:', max_i)
