I've a few more comments. First of all, please upload to redmine the full mdrun.debug output! It looks like the detection of the number of cores in your machine does not work with cygwin because when you only set "-ntmp 1" N OpenMP threads should be auto-set (N=#cores), but based on your output it

Hi, That is a likely cause. I can not comment with full certainty on the use of MARTINI with the Verlet scheme & without shifts, but I know that it is a topic that's being investigated and hopefully other can comment on it. However, the hanging should definitely not happen, but instead an error s

That's strange, it seems that mdrun gets stuck somewhere. This should not happen, but as we don't actively test cygwin, we can't be sure what's happening. It would be great if you could help us figure out what is going wrong. Could you try doing the following: - run with -ntmpi 1 -ntomp 1 (i.e sin

Hello, Thanks for the help. After setting the library path properly, I seem to be able to get gromacs up and running. However, I have run into another problem with mdrun and actually running any jobs. When I execute mdrun -v -deffnm Clp_Test -nt The output is: Reading file Clp_Test.tpr, V
