    Who cares to help with the left overs on NFS@Home?

    When wu's are aborted or left behind sometimes it delays the completion of a NFS sieve work.
    Greg, the administrator of NFS, can re-direct these type of work to individual not for an entire team. His question, and also my question, is for only 64-bit linux users although window users are welcome, who is willing to help to clean the left overs?
    Please post here your NFS@Home nickname so I can give Greg a list. Also tell me if you will be staying active for the duration of the two challenges.
    The behave of BOINC cleaning the left overs is very simple, you will get new and old wu's to be done as fast as you can while boinc itself aborts wu's already done by others faster than you. With this strategy we can easily clean the sieve of 2,1049+.

    Thank you.

    Hi Carlos, I may as well stay on it. I only have Win x64 though. Anyway, whatever he wants to send to the Drpop account, I will crunch it.

    I know BOINC is supposed to have some setting which allows work to be directed to machines which return work faster so jobs that have to get resent will get resent to hosts that not only complete tasks but complete them within a set time frame. I've never used it on Collatz so I can't give specifics but I know that the logic is in the server code so it is probably documented somewhere on the BOINC wiki.

    If I am not mistaken Greg uses a script for NFS@Home made by him.

    I am currently running two Linux 64-bit boxes on NFS, but I am sure nobody noticed! I will be running both challenge parts also. So I could help clean up, ran resent WU's on a couple on other projects. Getting a WU to finish in minutes is kind of exciting sometimes!
