To speed things up I made this: MB=600000; let PWMB=$MB/10; for i in {1..10}; do python -c "x=($PWMB*1024*1024/8)*(0,); import time; time.sleep(10*3600*24)" & echo "started" $i ; done | |

| Apr 4, 2017 at 20:03 | comment | added | Mike S | This solution worked to cobble up a Gig or two in my tests, though I didn't try to stress my memory. But, @JoachimSauer, one could set sysctl vm.swappiness=0 and furthermore set vm.min_free_kbytes to a small number, maybe 1024. I haven't tried it, but the docs say that this is how you control the quickness of swapping out... you should be able to make it quite slow indeed, to the point of causing an OOM condition on your machine. See kernel.org/doc/Documentation/sysctl/vm.txt and kernel.org/doc/gorman/html/understand/understand005.html | |

| Nov 8, 2013 at 23:04 | comment | added | Alexander Shcheblikin | Why would a unix swap while there is available RAM? This is actually a plausible way to evict disk cache when need be. | |
| Nov 8, 2013 at 13:22 | comment | added | Joachim Sauer | That will probably quickly be swapped out, having very little actual impact on memory pressure (unless you fill up all the swap as well, which will take a while, usually) | |
