If you did *don't* do that, let the build system pick what's best for you. However, if you did not do that, there is some issue with our auto-detection; a log file as a start would possibly help in identifying the issue. > > 1 GPU detected: > #0: NVIDIA GeForce GTX 670, compute cap.: 3.0, ECC: no, stat: compatible > > 1 GPU auto-selected to be used for this run: #0 > > Program mdrun-openmm, VERSION 4.6-beta3 > Source code file: > /home/own/gromacs-4.6-beta3/src/kernel/openmm_wrapper.cpp, line: 1367 > > Fatal error: > OpenMM exception caught while initializating: Error setting device > flags cannot set while device is active in this process > For more information and tips for troubleshooting, please check the GROMACS > website at http://www.gromacs.org/Documentation/Errors > > > I'm still using cuda-5-toolkit with the 304.54 driver.
