*** I know this topic will create fights about fair/unfair credits. Please try to avoid them this time. Thanks *** You can look at my computer here. As you see, there's only one result that has a higher claimed credit value than granted credit value. Could you please higher the credit distribution in order to be on a similar level than other projects? Thanks! (Remember: I'm not crunching for credits, but for the science, still the stats/credits keep it fun in the long run.) |

Enigma is using fixed credits, it doesn't care about the claims you make. Credit given is 8.35 (for _0_), 15.26 (for _1_) and 17.85 (for _2_). Jord. BOINC FAQ Service. |

Runtimes are predictable, so I calibrated credits with benchmarks and timings from my reference machine (Athlon TB 1400), using the standard app. I forgot the exact value, but it's around 7-7.5 credits/hour, which is quite high already. If you use cpu which doubles my reference machine's performance, you'll get same amount of credit, but the workunit runtime will drop to half of the original value, so you'll get twice as much credits/time. I believe it's fair. Btw, have you tried the optimized app ? :-> M4 Project homepage M4 Project wiki |

@ageless: I know it is using a fixed credit system, however it should always be around the claimed credit. @TJM: I'm using the optimized app, I love it!! |

@ageless: Not necessarily. For what if you then increase your measured integer speed artificially? That's how the claimed credit still works here: benchmarks times time taken. Enigma doesn't use floating point operations that much, so even setting the amount of fpops taken times a multiplier won't give a claimed credit anywhere near what is granted. The fp_benchmark_weight is set to 0.1, so it has no impact at all. Jord. BOINC FAQ Service. |

BOINC (default) benchmark doesn't show the real CPU speed. A quick example: Athlon Thunderbird 1400 c2d 1.86 The second one has only 50% higher benchmarks while in fact it's usually 3-5 times faster, depends on project. M4 Project homepage M4 Project wiki |
