Are you getting numerous downloads of this swamping your connection? Download speed on the 6MB file is only 15-25KB/s on my 12mbit connection...

The openmm link: http://proteneer.com/blog/openmm.org ends in an 404 error.

[proteneer]

It was pretty fast for me. I updated the openmm link, thanks

For me, it just give an error on an x64 Win7 system with 2x GTX460's that fold correctly: "Error loading library c:\temp\FAHBench_0_1\OpenMMOpenCL.dll: 126"

[artoar_11]

For me the same error:

C:\FAH> FAHBench.exe -deviceId 0 -platform CUDA -precision single

The download was also slow for me, and I also ran into the same error:

I notice the forward slash instead of a backslash. Perhaps that's the problem?

Also, your "Folding@Home" link to http://proteneer.com/blog/folding.stanford.edu is a 404.

Even though it didn't work, I do like the molecule artwork that you were able to draw in the command line.

Do I actually have to install the whole CUDA5 Toolkit to try this? I've got Visual Studio Express already, as well as NVidia 310.90 WHQL driver, which does have CUDA5 support.

[proteneer]

Are you guys using the latest drivers? Also, can you try running

http://www.dependencywalker.com/

on the OpenMMOpenCL.dll file that came with the benchmark?

[proteneer]

Unfortunately yes. The CUDA platform does a lot of JIT compilation and hence requires the nvcc compiler. We assume the user has the NVIDIA GPU COMPUTING TOOLKIT 5.0 installed (and hence why its able to find CUFF).

[proteneer]

Updated the download with some additional libraries - please redownload. Should fix OpenMMOpenCL.dll errors.

[k1wi]

Looks like the 126 error is fixed by installing the CUDA toolkit.

Having installed Visual Studio 2012 and then the CUDA toolkit rebooting I was stuck at the PATH error until I restarted the computer after adding the folder to the PATH list.

Having restarted with the computer I now get the following error:

Code: Select all

Error launching CUDA compiler: -1
nvcc : fatal error : nvcc cannot find a supported cl version. Only MSVC 9.0 and 
MSVC 10.0 are supported

It would look like by installing Visual Studio 2012 I have version 11 of MSVC?

Visual C++ 2012 (known also as Visual C++ 11.0) was released on April 15, 2012, and it is currently the latest stable release.

RTM version number: 17.00.50727.1

Yes it's looking for CUFFT in the 5.0 toolkit.

We compiled our code using Visual Studio 2008 (MSVC 9.0)- you can get the free express version here:

http://www.microsoft.com/en-us/download ... px?id=6506

Please don't use 2012 (MSVC11?) it's not supported. I'm not sure about 2010 (MSVC10).

Again, make sure the PATH includes the folder in which Visual Studio 2008's cl.exe is installed.

[k1wi]

Will I have to uninstall VS2012 before installing 08?

Might be useful to put that information on http://fahbench.com/ as your link goes to the 2012 version. ah already done.

No you don't need to uninstall VS2012. You just need to set your PATH so it points to the cl.exe in VS 2008

I didn't install the development driver in the CUDA toolkit, as it seemed to be pretty old (306.23, IIRC). 310.90 WHQL should support CUDA5. The nvcc.exe is the first thing in the PATH, now that the CUDA toolkit is installed. Tried both regular console and admin console, same result.

I can run for example "Stereo Disparity Computation" sample program which came with the toolkit, so I assume the toolkit installation was successful. According to GPU-Z it actually seems to do something on the GT430 because core clock briefly jumps from idle (50MHz) to 3D (810MHz).

Stereo Disparity Computation (SAD SIMD Intrinsics)

A CUDA program that demonstrates how to compute a stereo disparity map using SIMD SAD (Sum of Absolute Difference) intrinsics. Requires Compute Capability 2.0 or higher. Minspec: GeForce 400

What else could I try? Or is it just that my GT430 is too old to run the benchmark?

EDIT: if I try to run cl.exe from the console, I get "The program can't start because mspdb110.dll is missing from your computer. Try reinstalling the program to fix this problem." Well, this is a fresh install of the Visual Studio 2012 Express and all Windows updates are also installed, so I'm stumped with that one.

EDIT2: Never mind, I suppose I'll just have to try with the older version of VS Express.
