Great, thanks. Tom's have more users than we have currently, therefore we need more and better machines per user than them. >:

Hey guys! I've added a couple of machine, but they stand idle most of time not receiving wu. "No WUs available for this configuration"
Anybody else experiencing the same thing, or is it just me?
This "No WUs available for this configuration"
probably just means that the server at which the client was connected at the time was plain out of work to send out, not that you have a very unusual configuration.
At times, some GPU models could only get work if the client was opened up to beta workunits. But at the moment, this is AFAIK not necessary for any ~somewhat common GPU types.
It could also happen with very large CPU slots (i.e. many threads per CPU), especially if they had an "odd" number of threads configured. But AFAIK this really happens only on large servers; those are better configured to a power-of-two number of threads (or more generally a thread count which can be factored into small primes such as 2, 3, and 5 but ideally not more). Though if you happen to have such a large machine, note that one large CPU slot gives better PPD than two small CPU slots, as long as the large slot can get work.
If you check on the client with the advanced control (i.e. FAHControl) and see a slot waiting for a download with a "Next attempt" time which has gotten rather far off, then use "Pause" and then "Fold" per right-click on the slot. This gets the "Next attempt" period back to something more normal.
