My S@H average work done graph is plunging rapidly towards the nadir. The other two BOINC projects I am crunching are POGS and Asteroids, both of which are doing very well. So I selected "No new tasks" for both of those in hopes that S@H will catch up. So far, there has been no change. I am not really a techie, nor am I knowledgeable about tweaking the maximum performance from BOINC or out of my machine. I just let it crunch away. But this is supposed to be a fast computer and I think it can do better. It runs Windows 7 Home Premium 64. It has 8 GB of RAM and a 1 TB hard drive. The CPU is a dual processor AMD A6-6400K APU with Radeon HD Graphics. Its GPU is an AMD Radeon HD 7400/7500/8300/8400 series. Any remedies within my limited capabilities? Thanks. Steve G |

Hi Steven, RAC is based on average credit received over several weeks. Looking at your computer, only 27 work units have downloaded to your computer with 1/3 being from today. Of all the work downloaded, 9 were given credit for the last 5 weeks. It's no wonder your RAC is falling. Thats like 1.5 work unit for each week. If you want your RAC to climb, you are going to devote more time to Seti and crunch more work. It's good that you changed your setting and placed the other projects on NNT but it's going to take at least 1-1.5 weeks before you will see much change, and that's with constant crunching. Happy Crunching... Zalster |

There is also the outage Seti had last week. It sure kicked the hell out of my RAC with lack of work. |

Thank you Zalster for that explanation and suggestion. I will cut back on POGS and Asteroids. Steve G |

Thank you Zalster for that explanation and suggestion. For each project you can adjust the Resource share values in the preferences for each project. The value isn't restricted to 0-100. Any value up to 9999999 may be entered so that BOINC runs each project as much as you like. IF you are using the default setting for 100 for all 3 projects. Then BOINC is trying to allocate 33% of your computer time to each project. At least over the long term. It generally switched off and on projects rather than running all 3 concurrently.

Thank you Zalster for that explanation and suggestion. FYI, the resource share is a floating point number, so you can enter values like 1.0e+20 or 1.0e-20. Not sure if it is single precision or double. However even credit new will not even out the RAC between projects because there is too much leeway a project admin can use is granting credits. |

That is true. Asteroids credits pile up at many times the rate of S@H or Even POGS. I crunched S@H for about seven years with old and slow machines. Lost all of those credits because I can't remember the email addresses and passwords from them. Been doing S@H on this new machine since January 2013 and have 449,000 credits . Started Asteroids March 2014 and already have 1 1/2 million. Joined POGS November 2014 and have amassed a little over 244K. Don't seem fair somehow. I tried to reduce the allocation for Asteroids and POGS from 33%, but can't get them to change. I'll try harder. Thanks.

That is true. Asteroids credits pile up at many times the rate of S@H or Even POGS. Once you set the resource share, for the venue your computer is in, at Asteroids & POGS. Then in the BOINC client highlight each project & press the Update button. Once the communication with the project is finished the new values show be reflected in the client. If you has SETI@home set to 100 & the other two set to 50 then you would see Astroids 50 25% SETI@home 100 50% POGS 50 25% SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |
