--- Comment #11 from Joost VandeVondele <Joost.VandeVondele at mat dot ethz.ch> 2013-04-17 19:36:45 UTC --- With these patches in, parallel compilation of multi-file cp2k becomes significantly faster. Time for a full build goes from 70s to 50s. I think that in a parallel build the IO bottleneck (bandwidth) was significant, while this is now much improved. The effect will likely be even larger on mounted filesystems.
