2) Questions and Answers : GPU applications : problem running SETI on CUDA enabled IGP (Message 923653) Posted 5 Aug 2009 by Bob Post: Well, I have two CUDA-enabled systems (running XP Prof SP3). Now, I'm trying a Linux system. System is described below in the startup message log. I bought a GeForce 9800 GTX+, 512MB GDDR3 memory mainly to run BOINC. Everything seems to be set up right, latest recommended Linux BOINC software (64 bit ver 6.4.5), latest nVidia driver for Linux from their site(NVIDIA-Linux-x86_64-185.18.31-pkg2.run). Boinc sees the nVidia board when it starts up. But no downloads of CUDA work units. Profile (home) is the same profile used by the XP systems which are working fine with CUDA work units being downloaded and processed. Here's the message log from starting BOINC. Any suggestions of what to try?

3) Questions and Answers : GPU applications : problem running SETI on CUDA enabled IGP (Message 921864) Posted 28 Jul 2009 by Bob Post: I gave up on that one old system, and moved the nVidia board to another system. It works fine there. Might be some old driver on the older system, non-compatable hardware or software, but at this point, I'm not going to worry about it. Thanks everyone for the help and suggestions.

4) Questions and Answers : GPU applications : problem running SETI on CUDA enabled IGP (Message 919979) Posted 21 Jul 2009 by Bob Post: I very much doubt that they are normal errors, because I have had no completed CUDA tasks. But I hope that you can take a look soon, and see. I've been in programming for about 32 years (IBM mainframe), built a couple of systems that I'm running Seti on from scratch, but I can't figure out what the heck is going. Probably some conflict with something or other that I'm running/loading at startup, but nothing seems out of the ordinary to me. Want a list of starup stuff, until they get the duplicate database going again?

5) Questions and Answers : GPU applications : problem running SETI on CUDA enabled IGP (Message 919395) Posted 19 Jul 2009 by Bob Post: Uploaded and installed the latest driver from nVidia, 186.18.

6) Questions and Answers : GPU applications : problem running SETI on CUDA enabled IGP (Message 919375) Posted 19 Jul 2009 by Bob Post: I understand about communication errors. There was not anything put into the log about a computation error. It only showed up in the 'Tasks' display. After less than two minutes, the task completed, showed 100%, but in the 'Status' column, it said computation error. They then uploaded.
