Tuesday morning we reached 2 Billion BOINC results processed by SETI@home! Or to be more accurate, 2 to the power of 31 results (2,147,483,648). This explains why we haven't yet recovered from the weekly outage: we need to update code to accept larger numbers. -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea.

This explains why we're a little slow to recover from today's outage: we need to update code to accept larger numbers. Unsigned is not a long term solution! Congrats to the crunchers and the project. |

Very awesome. Now if this trend follows the population trend, we should be seeing our 3 billionth result sometime next year. |

Unsigned is not a long term solution! "Unsigned long" (4 bytes) is not a long term solution ;) but at rate of even a 100 000 Results per hour will give the project ~2.5 years to think about another fix :) Â - ALF - "Find out what you don't do well ..... then don't do it!" :) Â |

Unsigned is not a long term solution! Hmm, where I come from 4 bytes is just an int; ulong is 8 bytes. Mebbe you need to get a more modern computer. :-) |

Hmm, where I come from 4 bytes is just an int; ulong is 8 bytes. Depends on the compiler and the environment. I was doing some C++ stuff in Linux a few years back. Two machines, same distro, but one was 32-bit and the other was 64. ulong on 32-bit was 4 bytes, on 64-bit it was 8.

Great result for the project and all it's crunchers !!! Two days after I read the US government "has no proof aliens excist" I surely believe this private project will proof them wrong in my lifetime... Well, I think : people don't moan if you can't report your work... ET can wait another day ! For you guys at the lab : keep up the great job !!! |

wow. I don't have not even ONE work unit to crunch. Now that is super slow. And I am thinking on upgrading with a P6T7 motherboard and four GTX 570, I must be crazy. |

"wow. I don't have not even ONE work unit to crunch. Now that is super slow. And I am thinking on upgrading with a P6T7 motherboard and four GTX 570, I must be crazy." This is your best opportunity to do your upgrade. No WUs, the machine is nice and cool. You won't miss a thing. If you wait, your computer will be loaded up with work units and you might not have the heart to stop them. All of you crunchers out there contemplating an upgrade, take this as a sign and do it now. Strike while the iron is cold! :) |

Great result for the project and all it's crunchers !!! On The Other Hand, the US Government also doesn't have proof that aliens don't exist... ;-) . Hello, from Albany, CA!... |

I am sorry I have to respond to this: you cannot prove a negative. |

True, but they are celebrating 1 billion and there are no work units to work on for THREE days. I have my computer set for 10 days of work!! Something is not right. |

Hmm, where I come from 4 bytes is just an int; ulong is 8 bytes. Yes, I think the C Standard do not define the exact size in bytes of integer types. Maybe the size of unsigned long int is chosen to match the full size of CPU registers? (in 32-bit CPU mode the CPU registers are seen as 32-bit/4 bytes; And in 64-bit CPU mode the full length CPU registers are "unlocked" - 64-bit/8 bytes) As you can see different sites give different values for int size in bytes: http://en.wikipedia.org/wiki/C_variable_types_and_declarations http://ieng9.ucsd.edu/~cs30x/Std.C/types.html#Basic%20Integer%20Types http://www.cplusplus.com/doc/tutorial/variables/ Â - ALF - "Find out what you don't do well ..... then don't do it!" :) Â |

There have been limits in place for weeks now preventing caches from filling to anything near what you have set, depending on the speed of your computer. The limits have been in place due to a bad Boinc server code change, which still has not been fully corrected yet. It may be some weeks yet after the current situation is sorted for the original problem to be tackled. "Time is simply the mechanism that keeps everything from happening all at once." |

That "Something" is time needed to change the code and test it. Do you remember the Y2K problem? (dates written as 00 may be interpreted as 1900 or 2000 because only one byte was used for date in some old programs/databases) This is something similar - for now they can't accept your new results because you will get/return e.g. result #2,150,000,000 and they do not have "room" with such high a number in their "hotel".

The people on Seti make a great job. I just can´t belive only now somebody rememeber 2 billion results is the limit!!! |

Yes it has been several weeks that I have noticed that I don't receive a 10 load of work units. I have amd X6 (all 6 cores working) and two GTX 460se. This computer is 24/7 for seti@home. Been crunching since 1999. |
