Note about libxc/libnxc unpolarized functional

In a libxc or libnxc correlation functional, the current dftsw implementation always uses the functional in spin polarized form in calculations.

In the case of spin unpolarized systems with GGA, XC_POLARIZED Ec[$\rho_\uparrow$, $\rho_\downarrow$, $\sigma_{\uparrow\uparrow}$, $\sigma_{\uparrow\downarrow}$, $\sigma_{\downarrow\downarrow}$] (where $\rho_\downarrow = \rho_\uparrow$) is equivalent of XC_UNPOLARIZED Ec[$\rho_{tot}$, $\sigma_{tot}$].

NRLMOL Run Checklist

After you run NRLMOL, you should always inspect the calculation. This is to ensure that your calculation is correct or not. The below is a list of things to check.

Compiling PCM Driver on HPC with Intel Fortran - 2018 Edition (Updated: won't link)

A short note about how to compile PCM library on UTEP-HPC.
Update 7/6/2018 - This approach won't link.

0. Download cmake
Go to https://cmake.org/download/ and download cmake-3.11.0-Linux-x86_64.tar.gz
Extract the tarball file and you have cmake-3.11.0-Linux-x86_64/bin/cmake.
Add this cmake bin directory to your PATH.

1. Log in to HPC VCL
cd PCM2/
