[CP2K-user] [CP2K:20223] Hint about the compilation, prompted by "environment.F:920"

[Tau Chan]

Hi, everyone !

I have successfully compiled CP2K through toolchian in the installation 
package on my computer, but I encountered this hint in the out file after 
running a test:

 *** HINT in environment.F:920 :: The compiler target flags (generic) used 
***
 *** to build this binary cannot exploit all extensions of this CPU model  
    ***
 *** (x86_avx2). Consider compiler target flags as part of FCFLAGS and    
 ***
 *** CFLAGS (ARCH file).                                                    
                                    ***

Is this hint telling me I would improve the performance via any change in 
the compilation files? For example, may I aasign the variable "TARGET_CPU" 
to "x86_avx2" in the "install_cp2k_toolchain.sh" ? Thanks for any advice.

Best regards,
Tau Chan.
