Is there a change to no longer use Nvidia GT520
(Message 56392)
Posted 5 Dec 2012 by Sean Arrowsmith Post: Last night I noticed my PC auto-updated the nvidia graphics drivers via Microsoft update back to Nvidia drivers 306.97 and everything is still working. Running GPU-Z shows ticks for opencl and PhysX for 306.97 now whereas before it did not. Anyway as long as it works that is great. |

Posted 28 Nov 2012 by Sean Arrowsmith Post: I check my account on Milyway and surprised to see so many workunits there for the PC however in BOINC magaer there are no work units at all? I have detached from Milkyway and then rebooted. Reattached Milkyway and the issue is still there. I was running the latest Nvidia drivers 306.97, so I downgraded to 301.42 and rebooted and now I have all working. Running GPU-Z show no ticks for opencl and PhysX for 306.97 but after downgrade to 301.42 it shows a tick in opencl and PhysX So it looks like the 306.97 driver upgrade a few weeks back loses some functionality in at least the GT520 Thanks |

Posted 28 Nov 2012 by Sean Arrowsmith Post: Hi, Been using my GT520 for over 6 months to crunch MW GPU wu however over the last few weeks the GPU is no longer doing wu's. Has there been a change in the code or could I have a problem somewhere?

Do the WU get less credits now since thanksgiving crash
(Message 53405)
Posted 24 Feb 2012 by Sean Arrowsmith Post: Thanks, but could you help me understand a bit more where to find the credits per work unit from. I have had a look in my MW account under one of my PC's that runs 24/7 and look at the tasks. I noticed several MilkyWay@Home N-Body Simulation v0.80 (mt) tasks and they on average ran for.. Run Time 34secs CPU Time 44secs and I got an average of 0.73 credits. See link below, I am host 299165 http://milkyway.cs.rpi.edu/milkyway/workunit.php?wuid=88896154 So from this data I calculate as you say.... 86400 secs per day divide by 44 (is it 44 or would it be 34?) = 1963 Then multply 1963 by credits per work unit which is 0.73 = 1432 RAC OK, so it my max RAC for my host 299165 is 1432 but it's actual RAC is 749. So for host 299165 it's RAC before the Thanksgiving crash was at 1396, after the crash it dropped to 615 and then it slowly built up to 1226 by 11 December when the Server was replaced then the RAC dropped down to 425 and since then it has only managed to creep up to 749 over the last 7 weeks. This PC is on 24/7 and does nothing apart from MW cruching. It is a 32but Win7 PC on a Core Duo T2080 @ 1.73Ghz So you can see why I am asking about the RAC dropping that or my PC is shagged :-) |

(Message 53225)
Posted 16 Feb 2012 by Sean Arrowsmith Post: Hi, I am asking the question about the credits that are issue to WU sice November Crash Before the November crash I was stable at about 32,000 RAC, then after the thanksgiving crash it dropped directly to 18,000 and I slowly worked up to 28,000 and then there was the downtime for the new server and upon completion I had dropped down to 13,000 and so far I have climbed back up but only to 24,000 and it's dropping again. My PC's doing the crunching are still on for the same time periods as before the november crash but I just can not seem to crunch and get the same RAC. Do the WU now collect a smaller credit for completion. |

Lastest Stock Apps - Optimized or Not
(Message 49556)
Posted 25 Jun 2011 by Sean Arrowsmith Post: Thanks, after a bit of searching I found these OPTI apps on your site. I did notice a mistake with the downloaded Win64bit CPU files, in the app_info for the CPU version you are missing a < from the ending tag of name for the first opti app. see below. Upon running BOINC it complained about the missing app and delete it, upon placing the < into the file makes it work. <app_info> <app> <name>milkyway</name> </app> <file_info> <name>milkyway_separation_0.88_windows_x86_64.exe/name> <executable /> </file_info> <app_version> <app_name>milkyway</app_name> <version_num>88</version_num> <cmdline></cmdline> <file_ref> <file_name>milkyway_separation_0.88_windows_x86_64.exe</file_name> <main_program/> </file_ref> </app_version> </app_info> <app_info> <app> <name>milkyway</name> </app> <file_info> <name>milkyway_separation_0.82_windows_intelx86__cuda_opencl.exe</name> <executable /> </file_info> <app_version> <app_name>milkyway</app_name> <version_num>82</version_num> <flops>1.0e11</flops> <avg_ncpus>0.05</avg_ncpus> <max_ncpus>1</max_ncpus> <plan_class>cuda</plan_class> <coproc> <type>CUDA</type> <count>1</count> </coproc> <cmdline></cmdline> <file_ref> <file_name>milkyway_separation_0.82_windows_intelx86__cuda_opencl.exe</file_name> <main_program/> </file_ref> </app_version> </app_info> |

Lastest Stock Apps - Optimized or Not
(Message 49529)
Posted 24 Jun 2011 by Sean Arrowsmith Post: I have jut restarted MW after the last Optimized apps were dropped arounf April time. I have just reattached to MW and using the stock apps on a Win7 64bit with GTX460 Are the stock apps optimised versions or are there going to be NEW optimized version coming soon especially for CUDA I want to run 2 WU on my GTX460, the current stock app is only running one WU on the GTX460, can some one provide an app_info.xml file for the stock apps so I can modify the CUDA count to allow 2 WU Thanks |

Is MW going to be a GPU project now?
(Message 49027)
Posted 26 May 2011 by Sean Arrowsmith Post: That will be great to get a decent CPU app, not run a single MW WU since my PC upgrades to GTX460's coincided with the project upgrade and the Nvidia opti apps disappeared. |

Posted 28 Apr 2011 by Sean Arrowsmith Post: Hi, I have noticed that since 8th April my RAC on Milkyway clients has dropped drastically, one client used to run about and RAC of 600 and now is currently at 75, another which was at 500 is now at 37 (http://milkyway.cs.rpi.edu/milkyway/results.php?hostid=151848). These clients have not had their opt apps changed so why the decrease? |

hi whats going on with the RAC
(Message 39304)
Posted 30 Apr 2010 by Sean Arrowsmith Post: It started for me on the 15th March when my RAC dropped 30% overnight. I thought it was a problem with my PC's. I even altered the project split to give Milkyway more cruch time from 50% to 75% over SETI and my Milkyway RAC still kept dropping. I hope it starts to turn around soon. |

No New WU
(Message 37898)
Posted 1 Apr 2010 by Sean Arrowsmith Post: The RS is 80% Milkyway, 20%SETI I have just checked my other few clients and they are in the same position of just having SETI work and no Milkyway WU. One of the clients had run out 4 days ago of Milkyway WU but was still just collecting SETI WU as early as 1 hour ago. Suspending SETI and updating Milkyway got me 6 new WU and then resumed SETI. |

Posted 31 Mar 2010 by Sean Arrowsmith Post: I know there was some downtime on 19th March (12 days ago) but is this still happening now? I usually have a few days worth of WU in hand for downtime periods but currently at the moment I have nothing on my main machines just SETI. When pressing Update in BOINC I get these messages. 31/03/2010 15:52:10 Milkyway@home update requested by user |
