http://boincstats.com/en/stats/-1/cpcs Shows the comparisons. It should also be noted that the code to update the credit_per_cpu_sec field in the host records was deleted from BOINC about 2.5 years ago (changeset f65072a). At any project which is using a newer version of the BOINC server code, those values are whatever was previously there. Old hosts have a value, new hosts all have zeroes. In short, unless you know a project is running an ancient version of BOINC, the figures are meaningless. Joe |

What I find interesting is in looking at the two charts, the credit difference between Seti and SetiBeta. Same work units. Makes me think that the measuring stick is broken. You right, it's broken and long ago. And looks like never will be repaired. That's the single and right answer on original question. Because credits are not calibrated. Period. SETI apps news We're not gonna fight them. We're gonna transcend them. |

It should not matter who gives the most credit. It should be what project do you really want to crunch. For me Its Seti@Home. The other two I do like, but they are there for back up when I cant crunch S@H. [/quote] Old James |

Seti and Seti Beta don't have the same workunits (any more), Seti is using v6 Wu's still, while Seti Beta is using v7 Wu's, the data going into the Wu's is effectively the same, But the Beta Wu's are effectively larger now because of the added autocorrection signal searches, you can tell the difference whether or not the header has autocorrection values: <workunit_header> Claggy |

I am running SETI@home, Einstein@home and Test4Theory@home on one CPU. They never run in high priority. On the other CPU I run Albert@home (an Einstein Beta), LHC@home, Test4Theory@home and SETI@home Astropulse with a Lunatics app. Also CPDN@home with extended deadlines. They never run in high priority since I have a very small cache (0.25 day). All this on Linux. And yes, the second CPU also hosts a Solaris Virtual Machine with BOINC and SETI@home app by Dotsch.

Compared to S@H, Einstein has very short deadlines for the WUs, so your computer "is forced" to run Einstein with high priority. I must have had my cache set wrong then because I had never seen a task run at high priority till I joined Einstein, if I remember all the GPU tasks had very short deadlines and forced SETI to take a back seat till they had all cleared, I haven't touched my cache setting since I set them for Boinc 7. |

Compared to S@H, Einstein has very short deadlines for the WUs, so your computer "is forced" to run Einstein with high priority. The Einstein project itself has a 14 day deadline for all tasks. Their Beta project 'Albert' does set shorter deadlines of ~3 days for tasks/applications which are under active test, especially when they are approaching transfer to their main servers. That's done to ensure a rapid turnround, so that the staff can check the returned results quickly without delaying deployment - I think it's a legitimate tactic for a Beta project. [They are better resourced than SETI, staff-wise, so new application development and deployment happens at a faster pace there.] |

I would say Einstein offers SLIGHTLY more credits than SETI. Not massively more. If you just want big numbers to impress your friends with (and if so seriously reconsider your social circle) then try collatz. Honestly I feel I shed 50 IQ points while I crunched it. But my RAC was HUGE. Janice |

I would say Einstein offers SLIGHTLY more credits than SETI. Not massively more. But at GPUGrid, it heavily depends on the GPU you use, a FERMI or KEPPLER gives far more credit, compaired to the 8000/900 & 200 NVidia series. And for Collatz C. similar, Single Precision AMD/ATI GPUs do very well, especially 5770; 5870 (D.P.). |

I would say Einstein offers SLIGHTLY more credits than SETI. Not massively more. Yes but "if" the question is "just" about credit... not my case of course. I just want to show the big diference on the credit systems. Credit is just a way to compare the performance of diferent hosts beetween the same project, compare one project with the other ussing the credit is a compleate waste of time. |

Why is the credit for work done for Seti one tenth of that done for Einstein? Credit granted for Seti work is very small. Credit has gone down over time as a defacto means of encouraging people to leave Seti and donate resources elsewhere. This reduces the pressure on Seti's resources and thereby pushes out any urgent need for capital/infrastructure enhancement/replacement. Given the forthcoming increase in computational power of GPUs and the general migration of the base upwards (in terms of total processing power) I suspect that credit will once again be reduced in the next 12 months. |
