So I have a work laptop. It's my personal laptop that I use at work. It runs 5-10 hours a day 4 or 5 days a week. Just plugging along using someone elses power looking for ET right? Anyway I hadn't updated it so it was running mostly AP work units. Yesterday I updated the optimized app and noticed that the gpu work units were blowing through at a minute or less. DAMN this v.41 is faster. Now they are mostly inconclusive and invalid results. WHY? When I looked at my desk top with the radeon card the same type of work units were taking about an hour. Should I uninstall and reinstall everything? Help... stuck... Thanks |

You have 2 problem Computers: 1) http://setiathome.berkeley.edu/show_host_detail.php?hostid=6625355 NVIDIA driver 320.18 have bugs (especially for 2 GPU systems): http://setiathome.berkeley.edu/results.php?hostid=6625355&offset=0&show_names=0&state=6&appid= Update to 320.49 http://www.nvidia.com/object/win8-win7-winvista-32bit-320.49-whql-driver.html http://www.filehippo.com/download_nvidia_forceware_vista/ 2) http://setiathome.berkeley.edu/show_host_detail.php?hostid=6716264 Again driver problem: AMD/ATI driver 1.4.1589 (= Catalyst 11.10) is old The minimum needed for current SETI apps is Catalyst 11.12 Use this table for info and links: http://www.hal6000.com/seti/boinc_ati_gpu_cheat_sheet.htm ! If the laptop is 'special' you may need drivers from the laptop manufacturer and not from AMD/ATI (There may be other problems but it will be unclear until the drivers are updated) P.S. You didn't read the docs: In: ...\BOINC\projects\setiathome.berkeley.edu\docs\ Read: Lunatics ReadMe.txt "ATI MB apps - r1843; AP apps - r1843 ..... Minimum required driver: All OpenCL applications are compiled under SDK 2.6 so minimum driver is Catalyst 11.12 Accelerated Parallel Processing (APP) Technology Edition " Â - ALF - "Find out what you don't do well ..... then don't do it!" :) Â |

The driver was only part of the problem... I updated to 13.4 however I kept having the same problem 20-60 sec workunits. My driver info wouldn't update on the seti site either. I clicked update on the project tab, tried restarts, but the old driver kept showing for my computer. The fix was a uninstall of BOINC and APPs as well as a manual delete of the program data files. Reinstall and all is well and running smoothly! I fixed the nvidia driver on my desktop at home as well. Thanks for the help! P.S. I didn't read the readme file. I just figured all worked well under v.40 so v.41 should be the same with the v7 update. I'll be more careful in the future. |
