So far, the only cancelled unit is by FlyinfocRS of the Scottish Boinc Team!
NB. There is still nothing useful coming from the Admin over there. His only comment at this time fails completely to recognise the fact that everyone has far more work than they can possibly do. Here it is, as posted on Sztaki's Forum:
Hi Everyone,
due to the characteristics of the application it is hard to predict the running times of the workunits. Some will finish quick, some will take some time. However, the workunits - no matter how long they take to finish - are useful for the project and they are not defective. Please let your computer finish as much as it can, before the deadlines. Those which remain unprocessed after the reach of the deadline will be taken care by the server and will be sent out once more with a new deadline.
However, it is a problem that too many workunits gets sent out. I'm working on a solution for this.
