Dear GROMACS Users:
I used the C4mimNTf2 ionic liquid TOP and GRO files to run MD simulation.
Here are the commands that I used:
grompp -f em.mdp -c C4mimNTf2.gro -p c4mimNTf2.top -o NPT.tpr
mdrun -v -deffnm NPT
I got the following error messages:
Reading file NPT.tpr Version 4.6.5 (single precision)
Using 1 MPI thread
Using 1 OpenMP thread
Compiled acceleration: SSE4.1 (Gromacs could use AVX_256 on this machine,
which is better)
Illegal instruction (core dumped)..
Would you please explain the reason? How to fix this problem?
