Well, it's unfortunately getting a lot messier. I got cp2k compiled on 2
machines in the end, but I get bad results. On both machines, I use intel
17.0.2 compilers. Results on both machines are different (and presumably
wrong) from each other. I also compared results of the input file to
results obtained by an older versions (4.1 compiled with gcc on one
machine, 3.0 compiled with some intel compilers on the second machine;
these two installations gave same results). All energies except the self
energy is different:
"coorect"
Overlap energy of the core charge distribution:
0.00000310201993
Self energy of the core charge distribution:
-1007.31897988265303
Core Hamiltonian energy:
295.26625363987614
Hartree energy:
418.52562360415197
Exchange-correlation energy:
-101.48179826891138
Total energy:
-395.00889780551631
outer SCF iter = 1 RMS gradient = 0.00E+00 energy =
-395.0088978055
outer SCF loop converged in 1 iterations or 15 steps
ENERGY| Total FORCE_EVAL ( QS ) energy (a.u.):
-395.008897805517336
wrong output files are attached. I'm now trying to find out how to test
LIBINT, LIBXC, LIBXSMM and ELPA. Haven't had much luck yet.
Thank you for any suggestions.
