I mean a work unit! Just to make sure that I'm not being excluded from the full crossection of workunits available by setting my buffer to 2 days. Is this too short for some? Thanks, Guy.

There seem to be two types of WU - 100,000 and 1 million 'turns'. For me on a 2.4 P4 the short WUs take one hour, long ones 10 hours. Bear in mind that some short WUs end very quickly (seconds) if the modelled beam crashes in the wall. 2 day buffer should be fine. You may be limited by quota before you fill it though. Al. |

while there are more of the long 1m turn work units around, it made me wonder what sort of savepoints do the LHC wus have? none... every 1000 turns... every 10,000 turns? there's no search function on this message board, so sorry if it's been often mentioned before. I also fetched down an extra day of work in the buffer of the slower in my two rigs (they each take over a day on that one so you understand the savepoint question!) /pg |

My guess is that it can checkpoint on every turn, and since turns are so frequent, that will make it follow your preferences quite accurately (every 60 seconds by default). |
