Correct, both our nvidia driver package and ocl-icd (from epel?) provide 
the same file so they conflict with each other.

You will need to uninstall ocl-icd if you want to update to the latest 
version of the nvidia drivers from elrepo, to resolve that conflict.

Maybe ocl-icd is not installed on that system or you don't have the 
latest version of nvidia-x11-drv-390xx?

Correct. That's a minor oversight on my behalf. The nvidia-x11-drv-390xx 
and nvidia-x11-drv-390xx-libs packages go hand in hand - I added the 
Conflicts to nvidia-x11-drv-390xx but the library is actually provided 
by nvidia-x11-drv-390xx-libs. It shouldn't actually affect anything, but 
I'll fix that in the next release.

Yum has correctly identified libOpenCL.so.1 as a dependency but has then 
identified ocl-icd as the best option to resolve that dependency.

Try running the yum install gromacs again with epel disabled:

yum --disablerepo=epel install gromacs

Hopefully yum will then see that nvidia-x11-drv-340xx-libs provides 
those dependencies.

To check that is the case:

rpm -q --provides nvidia-x11-drv-libs | grep OPENCL
libOpenCL.so.1(OPENCL_1.0)(64bit)
libOpenCL.so.1(OPENCL_1.1)(64bit)
libOpenCL.so.1(OPENCL_1.2)(64bit)
libOpenCL.so.1(OPENCL_2.0)(64bit)

^^ that's from my install of nvidia-x11-drv-libs - try the same for your 
installation of nvidia-x11-drv-340xx-libs.

You will need to uninstall ocl-icd before you can perform this update.
