[Wien] Anyone experienced with openmp?

2018-09-24 Thread Laurence Marks
Currently the slowest part of the mixer is something which ifort does not want to thread parallelize. Is there anyone with openmp experience to suggest/check a minor optimization? Please respond directly to me. -- Professor Laurence Marks "Research is to see what everybody else has seen, and to

You create a surface slab model with a chemically realistic surface, and a reasonable vacuum, then add an atom or molecule. Supercell can help, but do not assume it will produce a valid structure. There is no reliable automatic tool for this, you will need to do it by hand aided by a tool to look

Technically you can use create_add_atom_clmsum_lapw. However, this may lead to a garbage calculation. You need to think carefully about the problem, look at prior literature for related systems and obey the basic rules of chemistry. If you do not do this you will end up with results which are

DFT+U and modifying the density matrix (case.dmatup/dn) by changing the occupations [1-5]. In the thread of posts and article of the two links you posted, it looks like they are using that.  So, good to see that you searched and found the answer to your own question. [1]

My previous email was rather misshaped by the mail client. I hope you can read this one more clearly. Please apologize. In $WIENROOT/SRC_kgen there is a file wn_readbakgen.f which may be compiled in order to substitute the corresponding executable in the XCrySDen distribution
