Nope, they are dual booted between Windows and Linux, so Linux is running AK optimized, and I moved some of them over to standard seti binaries in Windows. Hopefully they will all be up and running in a short while. Checkout http://seti.smlug.net for optimized Sun binaries. |

Well after some time I.ve managed to upload from other host same result.

So should we be doing the same. Or running 6.05 CUDA with 6.05 CUDA and not against MB. Michael |

... The credit method here is specifically implemented so that hosts doing the same work should report the same fpops_cumulative value used by the Scheduler to calculate credit claims. The stock CPU apps 6.03 and earlier in effect "count" flops based on the most generic code even though vectorized code may be in use for some functions. Optimized apps use the same counting. The 6.05 CUDA app ought to do the same, but obviously is getting extra "counts" for some WUs. I expect that's a temporary flaw which will be corrected after more serious problems have been fixed.

... 6.05 CUDA MB definitely ought to produce the same results as 6.03 and earlier non-CUDA MB, if not it needs to be fixed. Having both running here and no Adaptive Replication makes quickly finding any differences possible. Joe |

I seem to be consistantly underclaiming slightly on my results on this pc. I've done mostly shorties, show the difference hasn't been great yet, but as soon as I start getting some of the longer ones done, I expect the difference probably will increase. |

I'm experiencing similar for shorties. Underclaiming slightly...usually less than 1/2 a CS. Task list for computer 4715682. For longer WUs it's usually an Overclaim, not an underclaim. |
