Message boards : Graphics cards (GPUs) : What do "results" look like, why no independent validation?

I have never seen any "results" on this project though it is not as if all other projects return visible results. | |

That's surely a question worth asking. | |

Hi, This is one of those areas that sadly most projects neglect. That of explaining to the participants what the project is doing and how it is doing it. In the dark ages of history I used to try to capture nuggets like these and then to flesh them out so that the participant base could understand better what the project is doing. My gut feeling is that one of the reasons we have so much difficult attracting new and less committed participants is that almost no information about what the projects are doing actually makes it out in any organized fashion. That was why I had pushed so hard for a BOINC wide wiki so that we could develop the explanations of what the project was doing and how the experiments worked. Sadly the only project that took this task seriously (or was it just one guy on one project?) was CPDN where the mechanics of each experiment and model were explained in non-technical ways so that you could understand what was the point of the work we are doing ... | |

I think the main question is: if a fault does not lead to an obvious computation error but rather to a slightly wrong number here and there.. can this be detected without a wingman? Depending on how chaotic the system is this could lead to big errors in final results.. or could easily be corrected by following WUs. | |

It is nice to know that not everyone smokes the same stuff here. | |

Depending on how chaotic the system is this could lead to big errors in final results.. or could easily be corrected by following WUs. Or the system could depend on the chaos in the result stream to "properly" allow the system to diverge along the potential paths and only the statistical aggregation of all of the models is of interest. If I recall correctly this is something of the nature of what CPDN is doing ... though they are not using the output of one model to feed the next ... The only other project that I can think of that is using the output of models to feed forward is Milky Way ... | |

Either it recovers as the system will move towards the right sampling or it will fail. This is for not systematic errors. A card which produce continuous memory errors will simply fail the workunits. | |
