<div class="moz-cite-prefix">thanks, yes that is a reasonable way to
implement small changes without any side effects.</div>

effect the core of QE I am not sure if this is the way to proceed.</div>

<div>Dear Tobias, <br>
</div>
<div><br>
</div>
<div>This looks very interesting. <br>
</div>
<div><br>
</div>
<div>The recommended way is to fork QE, apply your changes, make
sure the test-suite still works in sequential and parallel
(q-e/test-suite) and then make a pull request on gitlab.</div>
<div>If you introduce new features (like new input variables),
please also add a test to test it [I'm happy to help with
adding new tests if its an issue]. <br>

<div>Interesting, but ... it seems to me that you have been
working on "CPMD" from <a href="http://www.cpmd.org"
target="_blank" moz-do-not-send="true">www.cpmd.org</a>.
This is a different project, not part of Quantum ESPRESSO.
There is a similar Car-Parrinello code called "CP" in QE.
Are you considering porting your improvements to the CP
code of QE as well? that would be great<br>

in the last two years I reworked the USPP code of CPMD and
obtained <br>
quite impressive results. E.g.<br>
<a
href="https://sc18.supercomputing.org/proceedings/tech_poster/tech_poster_pages/post189.html"
rel="noreferrer" target="_blank" moz-do-not-send="true">https://sc18.supercomputing.org/proceedings/tech_poster/tech_poster_pages/post189.html</a><br>
<br>
Please also find some updated performance plots on
SUPERMUC-NG (Skylake <br>
48 cores/Node):<br>
<br>
NCPP/USPP comparison for the current CPMD 4.3 and my
reworked version<br>
timestep = 0.145 fs, 256 water molecules, 1024 states,<br>
USPP: 2560 beta projectors, 25 Ry<br>
NCPP: 512 beta projectors, 80 Ry<br>
4.3: PS_per_day_nc-old-ng.pdf<br>
rev: PS_per_day_nc-new-ng.pdf<br>
<br>
and some more water benchmarks from 32-2048 molecules.<br>
<br>
<br>
Currently I am thinking of applying the same optimizations
to QE, so the <br>
big question is what are your thoughts about this?<br>
I had to rework quite a large portion of the code (~ 14625
additions and <br>
6576 deletions) so the question is really how I could
proceed:<br>
a) Fork QE and just rewrite the parts of the code that are
important on <br>
my side<br>
b) Fork QE and try to keep everything mergeable<br>
c) Directly create small patches<br>
<br>
So for now, please just let me know if there is some
interest on your side.<br>
<br>
Kind reagrds,<br>
