Hi, on the download page, there are Linux-Gromacs-OpenMM and MacOS-Gromacs-OpenMM. Is there a way to install Gromacs-OpenMM on Windows?

Can I compile Gromcas-4.0.5 using Cygwin and install OpenMM-Windows, and link it somehow?

Hi Mohd,

One solution would be to download OpenMM Zephyr (https://simtk.org/project/xml/downloads ... oup_id=352) and use the mdrun_openmm executable. The Zephyr manual gives details on how to setup and run Gromacs/OpenMM simulations from the command line.

Thank you. I found that solution when browsing the forum earlier.

On the other hand, the forum is really weird. If I enter the forum at different times, or from different links, I get different lists of topics. Anyone else is getting the same behavior? I tried reloading the forum thinking that it is a cookie problem. I have the same problem on IE8 and Firefox 3.6.

I am trying to compile on 64-bit windows 7. When I run cmake. I get the following

CMake Error: Parse error in cache file C:/Users/jshultz/Documents/Visual Studio 2008/Projects/OpenMM1.1-Source/src/CMakeCache.txt. Offending entry: MS-DOS style path detected_ C_/Users/jshultz/Documents/Visual Studio 2008/Projects/OpenMM1.1-Source/src/.svn/entries

It's not obvious to me what the trouble might be. We don't have much experience building on 64-bit Windows, nor on Windows 7.

Are you by any chance running the cygwin cmake executable rather than native windows cmake?

Does Zephyr run correctly on your system?

Using CMake 2.8.0 windows gui. I will try building again on xp 32-bit. Zephyr runs. I selected NVIDIA GPU. I tried running it from the command line and it fails to read the params.agb

When you run Zephyr binaries from the command line, you need to set certain environment variables correctly. This should be described in chapter 5 of the Zephyr manual. Failure to find params.agb suggests that the GMXLIB variable needs to be set to a particular directory within the Zephyr install. Alternatively, you could copy the file params.agb from the Zephyr install folder to your Gromacs install folder.

Hi,
I am trying to use mdrun_openmm.exe (found in Zephyr install) from command line on 64-bit Windows 7. I have added the environment variables as mentioned in Chapter 5 of the Zephyr manual as follows:

set GMXLIB=C:\Zephybin\gmxlib
PATH=C:\Zephyr\bin\win32;%PATH%
set OPENMM_PLUGIN_DIR=C:\Zephyr\bin\win32\lin\openmm\nvidia

In spite of this, when I run the exe, I get
OpenMM Platform: Reference

I have no idea why it wouldn't run on Cuda even though all the drivers and CUDA Toolkit/SDK are in place.

Any help would be appreciated.

Thanks,
Shashi

Update:
When I change the environment variable to point to OpenCL, it works. But, it doesn't work for CUDA.

What could be the reason behind it?

Thanks,
Shashi

That's quite strange that OpenCL would work but not CUDA. Just to check a few points:

- What GPU do you have?
- What happens when you run a simulation through the Zephyr application? Does CUDA work then?
- What version of CUDA do you have installed?
- Are the CUDA and OpenCL plugins both present in the plugins directory?
