Hi there, I have installed the gromacs-4.5.1 and it was running without problems. Also I installed the GPU version of GROMACS (gromacs-4.5-GPU-beta2). I have a GTX 480, and the CUDA libraries and NVIDIA driver are installed. Then I tried to run the test provided by Alan with the mdrun-gpu and I got an error.
