H A D | mman.h | diff 49f0ce5f92321cdcf741e35f385669a421013cb7 Tue Jan 21 17:49:14 CST 2014 Jerome Marchand <jmarchan@redhat.com> mm: add overcommit_kbytes sysctl variable
Some applications that run on HPC clusters are designed around the availability of RAM and the overcommit ratio is fine tuned to get the maximum usage of memory without swapping. With growing memory, the 1%-of-all-RAM grain provided by overcommit_ratio has become too coarse for these workload (on a 2TB machine it represents no less than 20GB).
This patch adds the new overcommit_kbytes sysctl variable that allow a much finer grain.
