does "ENABLE_NATIVE_OPTIMIZATION" works ?

[Satinelamp]

I noticed that there is a building option called ENABLE_NATIVE_OPTIMIZATION, does this option accelerate abacus?
I tried to use this option, doesn't get a better performance.

Hi @Satinelamp ,
This option will make the compiler use of all the available instructions of CPU. From my test result it would make ABACUS run ~10% faster.
However, the heavy-lifting calculations is accomplished in third-party libraries, like ELPA and OpenBLAS. I would suggest you using corresponding flags on them to gain a better performance.
