20th June: Website now working again! - and after 21 years UBT is still here and we continue to crunch :-) (PS: I still have no idea where the UBT logo went !)
When you have no work, set the target CPU run time in RALPH preferences as low as possible, once you have a load of WUs, go and adjust it to a much higher value. This extends the lengths of the WUs you already have, even the running ones! Just watch out for deadlines!
