<br>I cannot reproduce this behaviour. Can you send an example and
<br>specify the job parameters (serial/parallel, number of nodes)?
<br>
<br>thank you

<br>Subject: [CP2K:4408] changes between 2.1 and 2.3/2.4-trunk inside calculate_dispersion_pairpot subroutine
<br>
<br>Hi,
<br>
<br>I've recently came across a problem with the 'calculate_dispersion_pairpot' subroutine inside the qs_dispersion_pairpot.F file. The 2.4 version of that subroutine is being executed ~6x slower than that of 2.1 (~6s in place of ~1s). This was initially reported to me by one of our users running his jobs on our cluster. The builds of both 2.4 and 2.1 are practically the same.
<br>
<br>Any thoughts and ideas about it?
<br>
<br>regards and thanks in advance,
<br>
