Description

Hello

While testing our GROMACS installation, I used an input file from one of our users. It works well on GROMACS 2018.3, but not on GROMACS 2019.1.
In both cases, I used the same compiler (Intel 2018u3), same configuration settings to compile GROMACS, same hardware and same parameters to mdrun.
In attachment, I add input files (0519-2018.tpr is for 2018.1, 0519.tpr is for 2019.1) and logfiles from the 2019.1 run.
Should I change something to the configuration settings to get it working? Thanks!

FYI: The same input file does work on the user's workstation (single node) using GCC 7.3 and NVIDIA's v10 toolbox.

Kind regards
Stefan

Hi Stefan,

Can you try to run "make check" (ideally with all the regressiontests enabled too)? That might be able to help us diagnose right away whether it's a compiler issue.

Cheers,

Erik

Hello Erik

I already ran "make check" (with regression tests) for issue #2876, but it seemed the few errors reported were not serious.

Kind regards
Stefan

Hello Erik

Just an update: it's exactly the same problem with GROMACS 2019.2, compiled as described above with Intel 2018u3.
Do you have any suggestions to get this computation working in GROMACS 2019.x? Thanks!

Kind regards
Stefan
