Early Unit End ??

I was looking at the status log on my Folding machine. I got a "Gromacs cannot continue further". "Going to send back what have done".
What has happened here? Did my computer not finish the work, or did Stanford teminate the work?
Thanks;
Dragstk
PS> and in related questions-what's a Tinker?

    Tinker and Gromacs are different modeling or calcualtion methods. They use different data files and different processes. The Tinkers are the older ones. They still use them because they are better (yield better results) for some calculations. I am sure that you have noticed that they are slow.
    Don't worry about the early finish unless it happens a lot. Some units just reach a point where they cannot be processed further. If this starts happening often then you need to worry about system stabiltiy.

    Please post your log file, at least the problematic part.

    Tinkers vs gromacs. Gromacs use SSE, 3dnow!, and Ativec (Mac) assembly optimizations. The tinkers do not use any optimizations. Tinkers and gromacs use different cores: core_78=gromacs and core_65=tinker.

    Despite my best efforts and the efforts of friends, I cannot get my 2 computers to talk to each other. And until right now, it hasn't ben a problem.
    basically:
    at step 71, I got the "Gromacs cannot continue further"
    it connected, and sent back the work. I got a thank you for my contribution
    then, it got another work packet and started work on a different project. Which at this point is about 1/3 done.
    Thanks for the info;

    I have read about some of you working on Tinkers, but I have yet to get one. I am running an AMD w/SSE.

    Gromacs are better.

    Kinda sounds like its just a WU error. It happens once in awhile.

    These folding calculations are interative. Each step uses the resluts of the previous step as an input. In this situation sometimes you calcualte yourself into a corner and you can't proceed. Remember, they don't know the answers ahead of time. Sometimes they set up conditions that don't lead to a final result. It is important to the project that they know where the dead ends are also.
