Dear Makoto Yoneya,
Thank you for the feedback, it is of great help!
I will try to reproduce the issue because mdrun should not segfault with
any gcc version 4.3 and above. Could you please provide two more things:
- a log file of the failed run using the latest code from git;
- run mdrun with

On Gromacs 4.6 segmentation fault with mdrun,
I'd also met the same segmentation fault problem with gromacs-4.6.
on my linux box with GTX-580.
For my case, change the compilor solved this problem.

Hi Szilárd and Roland,
Thanks for the clear explanation!
I will compile release-4.6 (instead of the nbnxn_hybrid_acc branch) and
do some further testing in a few weeks since I'm currently using the
machine for production-runs with gmx-4.5.5.
Thanks for your time and effort!
regards,
raf

Roland,
He explicitly stated that he is using 20da718 which is also from the
nbnxn_hybrid_acc branch.
Raf, as Roland said, get the release-4-6 ad try again!
There's an important thing to mention: your hardware configuration is
probably quite imbalanced and the default settings are certainly
Hi Raf,
which version of Gromacs did you use? If you used branch nbnxn_hybrid_acc
please use branch release-4-6 instead and see whether that fixes your
issue. If not please open a bug and upload your log file and your tpr.

Hi Szilárd,
I assume I get the same segmentation fault error as Sebastian (don't
shoot if not so). I have 2 NVIDA GTX580 cards (and 4x12-core amd64
opteron 6174).
in brief :
Program received signal SIGSEGV, Segmentation fault.

Dear GROMACS user,
I am running in major problems trying to use gromacs 4.6 on my desktop
with two GTX 670 GPU's and one i7 cpu. On the system I installed the
CUDA 4.2, running fine for many different test programs.
Compiling the git version of gromacs 4.6 with hybrid acceleration I get
one error

Hi Sebastian,
That is very likely a bug so I'd appreciate if you could provide a bit more
information, like:
- OS, compiler
- results of runs with the following configurations:
- mdrun -nb cpu (to run CPU-only with Verlet scheme)
- GMX_EMULATE_GPU=1 mdrun -nb gpu (to run GPU emulation using
