Hello,
I freshly installed Gromacs 4.0, but when I run the test set 3.3.3, I
get "segmentation fault error".
1. 4.0.2 is out, you shouldn't do fresh installs of bugfixed software.
2. Also don't enable threads - it does nothing for FFTW for GROMACS, but
won't hurt.
3. Don't compile software as root if you can avoid it. If you do, some
trivial error in some script can trash your whole system. You should
reduce your exposure by only doing "make install" (or for GROMACS, "made
install-mdrun") as root.
My installation script, no error during the compilation :
$ pgcc -V
pgcc 7.2-2 64-bit target on x86-64 Linux -tp k8-64

You've only made MPI-aware gromacs in double precision. That's probably
not what you want. See the installation guide on the GROMACS website.
-------------------------------------------
First I run the test without mpi (/usr/local/gromacs-4.0.0)
I can't really help with this.
