I built this last night on a Mythbuntu 8.10 system with an 8400 GS card, and Nvidia driver 180.41. Used the cuda 2.1 toolkit for Ubuntu 8.04 (seemed like the closest match). There were a few warnings at compilation. export LD_LIBRARY_PATH=/usr/local/cuda/lib ./memtest seemed to start ok, putting up a bunch of reasonable looking information about the graphics card, then it gets down to a "bit test" line, then sits there for a very long time. CPU usage is at 100%. There are no periodic status messages. Eventually the screen goes blank and it stops. This isn't the normal screen blanking, the screen is wiped clean, but hitting a return pulls up the prompt. This was running as root in single user console mode (no X11). Oddly, output even though this was running in bash, output could not be redirected with ./memtest 2>&1 | tee mytest.log When run that way, nothing showed up in either the file or on the screen. memtest allocated 222 MB (if memory serves) out of the 256MB on the card. Anyway, I seem to be doing something wrong. Does this code need to be run in an ssh with the monitor not attached? Maybe driver 180.41 is not fully cuda capable? Why won't the output redirect?
