Following kind guidance by Lennart Sorensen as to the correct installation of the nvidia driver, I recently got a two GTX-470 computer work perfectly for molecular dynamics simulations with NAMD-CUDA.
The simulations were launched from linux terminal, without calling the X server. Command (as root) nvidia-smi -L was first needed to activate the GTX 470 cards (udev normal affair) ******************** On 27Jun the system was upgraded from driver 270.41.19 to 275.09.07. On rebooting, dkms did its job for the existing headers 2.6.38-2. However, now the above NAMD-CUDA MD launching does not work any more. Sincerely I can't say if the crash described below occurred immediately after the driver upgrading, but the dates are very close. Now, on launching MD as above described, the system hangs, the screen shows blinking characters and letters, and the power must be shut down. The log of the simulation says CUDA error cudaStreamCreate on P2 0 which is a normal message of NAMD when the graphic boards are not seen. However, the computer should not hang. Launching NAMD-CUDA from a terminal window of gnome-2, the procedure runs correctly. I understand that this report fails to analyze correctly what happens. It is a simple warning to see if other amd64 users had problems with the new nvidia driver. thanks francesco pietra -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
