Hello all,
Is there anyone know that whether the Abinit6.6.3 support the Intel new AVX instruction or not? Thanks.

Who knows? Might be.
If you want to try it, you'll have to provide additional flags yourself through the FCFLAGS_EXTRA environment variable when running configure. You'll find them in the Intel documentation.
Please let us know whether it worked and, if yes, thank you for sending us the corresponding flags.

Simple addition of compiler flags is not enough. I read about it.
