Posted 21 Sep 2008 by Alex Post: One other thing... whatever\\\'s going on with the sixtrack_4.67_windows_intelx86.exe , it seems to occasionally cause Windows to play the Error Sound Event. However I have no messages on screen or in the BOINC messages area to give me any more information. I\\\'ve checked the computer\\\'s event log and there\\\'s nothing in there either. I got around the Vista permissions thing by installing Boinc in a separate directory than the default \'my programs\' location. I run it from it\'s own \'boinc\' folder on the C drive. |

Posted 21 Sep 2008 by Alex Post: If you have a short WU and the server has 3 sucess results of this, then this WU will be aborted by the project. Seems like boinc server is getting fixed up. If the computers do crunch these work units, they only waste a couple seconds of cpu time. |

Practical uses for mini black holes.
(Message 20299)
Posted 13 Sep 2008 by Alex Post: A lot of people have been worried about mini black holes causing trouble, but in reality, they can be beneficial. Zero emission vehicles: just attach a mini black hole to the tail pipe, and no more smog, no more CO2. A better vacuum cleaner. Throw out your old Dyson vac, and get a mini black hole vac. It\'ll really suck the dirt out of the carpet, and there\'s no dust bin to empty out. Garbage disposal - just have a mini black hole under the sink - no more need to take out the trash. And no more need for landfills either. Make the work day go by faster. Bring a mini black hole to your cubicle, and put in a 1 hour day. Due to time dilation, 8 hours will have passed in the rest of the company, and you can then go home. You can even use one in the car to make the commute go by faster. They attract members of the opposite sex!* * Gravitational attraction. (Caution: they attract larger people even more) Diet pill. If you have one in pill form, it will eat your food for you, so you can enjoy all the dessert you can eat and not worry about getting fat. Tunneling - attach one to the front of a Tunnel boring machine and it will cut out a clean circular tunnel without having to replace cutters. So, there you have it. Seven ways that mini black holes can make your life better. |

Posted 19 Jul 2008 by Alex Post: I skipped to the summary at the end. A lot of the 'Theories of everything' tend to just cram the existing equations together with the focus on making the math fit. If the LHC does end up finding the higgs particle. The real fun will be in when they do experiments to see how that shiny new thing interacts with everything else. |

(Message 19172)
Posted 6 Mar 2008 by Alex Post: When this project started, they were getting different results from AMD versus intel pc's, and they would have three intel machines with one result, and one or two other machines with a similar result, but outside of the matching spec of the first group of three. There's a feature where the second group of results gets half credit. Your result has the 'invalid' tag, because it didn't completely validate. Most likely it's because of errors in the simulation propagating over 1,000,000 turns instead of 100,000 turns. Possible causes of floating point errors could be: Your floating point processor is different.. you can test it with Testfloat to see if it passes the Ieee744 spec http://www.math.utah.edu/~beebe/software/ieee/ Your PC could be heating up. I once had and IBM which didn't have the heat sink properly seated from the factory.. so it would act up after a couple of hours. Your PC may be overclocked. Most software is integer based and uses boolean logic, but floating point errors rarely cause a program to exit with an error. In fact you could have a wrong result in the last digit when you calculate the square root of two, but nobody would notice unless they're a super math geek. |
