1) Message boards : Number crunching : CPU: Run nbody simulation only (Message 44191) Posted 24 Nov 2010 by Geras Post: Hi, I managed to modify app_info.xml file to use Fermi CUDA (MW_0.24_CUDA.zip) modified by Crunch3r from http://www.arkayn.us/milkyway and MilkyWay@Home nbody Simulation together. If it helps somebody. :-)
2) Message boards : Number crunching : Computation errors? (Message 44133) Posted 23 Nov 2010 by Geras Post: A-a-a-and, YES!!! The job started without crash finally! Goood. All tasks were successfully loaded (18), 1 finished and under validation now. Unfortunately I couldn't use CPU for Milkyway project now with this modified files: "23/11/2010 23:13:54 Milkyway@home Message from server: Your app_info.xml file doesn't have a version of MilkyWay@Home N-Body Simulation."
3) Message boards : Number crunching : Computation errors? (Message 44132) Posted 23 Nov 2010 by Geras Post: Oh, how interesting. Just found the reason. The assigning of the file name of: "<app_info> <app> <name>milkyway</name> </app> <file_info> <name>milkyway_windows_intelx86__cuda23.exe</name> <executable/> </file_info>" is wrong! I copied the file name from the file manager and pasted it into the assigning section <name>*******(here)********.exe</name>. The names seemed equal from the beginning but only the newly pasted makes no errors when BOINC start. I hope it will help somebody.
4) Message boards : Number crunching : Computation errors? (Message 44130) Posted 23 Nov 2010 by Geras Post: Fermi class NVIDIA cards are not supported by the default MilkyWay CUDA application. You need to download and install version 0.24: Fermi CUDA (MW_0.24_CUDA.zip) modified by Crunch3r from http://www.arkayn.us/milkyway 1) Stop BOINC by going to the advanced menu and selecting "Shut down connected client", click okay and then click cancel. Then exit out of the BOINC Manager. 2) Unzip the MW_0.24_CUDA.zip file you downloaded. 3) Copy the 4 files, app_info.xml, milkyway_windows_intelx86__cuda23.exe, cutil.dll, cudart.dll to your BOINC\projects\milkyway.cs.rpi.edu_milkyway folder. Windows 98/SE/ME: C:\Windows\All Users\BOINC\ or C:\Windows\Profiles\All Users\BOINC\ Windows 2000/XP: C:\Documents and Settings\All Users\Application Data\BOINC\ Windows Vista and Windows 7: C:\ProgramData\BOINC\ There is a file called "app_info.xml" included that will make BOINC use this app automatically. 4) Restart BOINC by reopening BOINC Manager. BOINC will tell you in Messages tab that it found app_info.xml and is using an "anonymous platform". Hi, I did as you described and found I row as "23/11/2010 23:02:55 Milkyway@home Found app_info.xml; using anonymous platform" BUT!!! The next messages from the project were: 23/11/2010 23:02:55 Milkyway@home [error] State file error: missing application milkyway_nbody 23/11/2010 23:02:55 Milkyway@home [error] Can't handle workunit in state file 23/11/2010 23:02:55 Milkyway@home [error] State file error: missing application milkyway_nbody 23/11/2010 23:02:55 Milkyway@home [error] Can't handle workunit in state file 23/11/2010 23:02:55 Milkyway@home [error] State file error: missing task de_nbody_model6_3_21065_1290515179 23/11/2010 23:02:55 Milkyway@home [error] Can't link task de_nbody_model6_3_21065_1290515179_0 in state file 23/11/2010 23:02:55 Milkyway@home [error] State file error: missing task de_nbody_model5_3_810_1290534245 23/11/2010 23:02:55 Milkyway@home [error] Can't link task de_nbody_model5_3_810_1290534245_0 in state file 23/11/2010 23:02:55 Milkyway@home [error] No application found for task: windows_intelx86 45 sse2; discarding 23/11/2010 23:02:55 Milkyway@home [error] State file error: result de_nbody_model6_3_21065_1290515179_0 not found for task What changes they expect in .xml file to do?
