The project is using the "old" BOINC credit algorithm. If I remember how it works, the very first few tasks on a new application that BOINC sees gives very high credit. Then when more tasks are returned the algorithm tunes the credit downwards. The APR for the application stabilizes after 11 valid tasks have been returned. This project utilizes the application APR function of BOINC. It is up to each project to decide whether to follow BOINC standards or write their own. So far I have seen credit awards of 160, 21 and 7. That must be because those were 3 different molecules. |

Seems to me that credit should be based on CPU time only. One WU should be worth a specific amount of credit regardless of how fast or slowly processed. Probably require a large bureaucratic committee to attempt to quantify such a value but that's my 2 cents and maybe it would be worth it if we get an answer within a few years :). Edit: Added last sentence, sorry, couldn't resist. |

That's how Einstein handles credit. They don't use the BOINC algorithm and decide how much credit any application awards independent of run_time. |

Just posting to say that I have finally gotten my 6 core Phenom CPU working on this project. It has taken me about 3 months of errors and an OS upgrade from Fedora 16 to 21, before the error message changed, saying that now qmml/bin/python was not there. So after comparing another working system and a huge number of updates, I noticed that a number of symlinks were missing from my computer. I installed 7 symlinks, all python related. Existing files........Missing files pydoc3.6 >>>>>>>>>>> pydoc pydoc3.6 >>>>>>>>>>> pydoc3 python3.6 >>>>>>>>>> python python3.6 >>>>>>>>>> python3 pyvenv-3.6 >>>>>>>>> pyvenv python3.6m-config >> python3.6-config python3.6m-config >> python3-config After installing all of these links it now has begun to work. So Toni, hopefully no more errors. Conan |
