Hello,
I continue to have difficulties with my newest gromacs compilation
(3.3.1). The errors that I report here are entirely absent from other
clusters on which I have compiled gromacs.
The error now is in grompp and looks like this:
Opened sys1800_md689.edr as single precision energy file
Reading frame 0 time 35250.000 Floating point exception
(core dumped)
Everything works fine if I remove the -e x.edr from the grompp
command. If I copy all files over to a different cluster and run the
original command there is no error so this is compilation dependent.
Does anybody have any insight into why I would have this particular
problem on one installation and not on another?
gmxcheck on the .edr file indicated that it is fine.
Thanks,
Chris.
