Silent Folder calling.
Probably been asked before, but why do the Pande group allow the ASs to run out of WUs.
I have two 7970s sitting waiting to crunch numbers for them. Although the 660TIs still seem to get WUs.
One, the AS never runs out of WUs as it never has any. Only work servers have WUs.
And the problem is usually just the opposite. The work server fills up with completed work, and it takes more time to shift those terabytes of data than it does adding new work units.
And since that rarely happens with any planned regularity or at a convenient time of day, it has to sit over night until the next day when humans come back to work.
And normally there are other projects and work servers to take up the slack, like always happens with SMP work now days. But GPU folding is in a transition from older cores and old projects to newer cores and new projects, so there will be some occassional gaps.

I started seeing problems early this morning (east coast time) on one of my machines that had not been upgraded from 7.3.6 yet, so I upgraded to 7.4.4 in the hopes of getting the backup server.
That worked to get a Core_16 on one machine, but I am still out of luck on another. It looks like we are in for a long siege.

As previous WUs are completed, the server generates a new Gen, but it is quickly assigned, quickly reverting to the empty condition. I'll notify the Pande Group, but it's late in California I doubt conditions will change tonight.
Just a remark here : I noticed during the last few days a strong increase in the number of Fermi/Kepler GPU reported as folding - see
http://fah-web.stanford.edu/cgi-bin/mai ... e=osstats2 - more than 44k Fermi/Kepler GPUs when in my memory the usual figure was around 30-40k. Is there any chance some anonymous corporate donor with rooms filled of idle GPUs started folding recently, thus contributing to dry out Core 17 assignments ?

That is a well-founded guess. Anonymous corporate donors do contribute to FAH from time to time. (Since they choose to remain anonymous, nobody can answer your question.) Moreover, like regular donors, they're going to contribute whatever hardware they have whenever they choose to, and if that causes unplanned distortions of the assignment process, the Pande Group will have to respond in whatever ways are necessary.
Restarting a downed server may take a few minutes unless the filesystem needs checking, and then it can take a few DAYS. Offloading completed work from a server to make room for new work often takes time. Developing new projects to replace ones which have been completed takes even more time. If new servers need to be added, it takes money, planning, and even more time. The bottom line: Since we don't know what critical resources are required, we can't predict whether solving a WU shortage may take a day or many days and all necessary steps must be done carefully.
The PG is generally MORE concerned when donors have resources that could be used than those donors (you) are yourselves.

I guess so, Dr Pande just confirmed a big donation from corporate partner, see

I can entirely understand that PG cannot decline large donations of computing power, wherever they come from, but they need to find better ways of dealing with them.
A short-term benefit at the expense of hacking off numbers of long-term donors could very easily become counter-productive.
Dr Pande is clearly not unaware of the the problem, but phrases like "online shortly" and "hopefully just briefly annoying" are not particularly helpful. How long is "shortly"? How prolonged is "brief"? Hours? Days?
At least let's have some useful information!!!!!

Sorry, soon = later today. I'll work to be more precise in future posts. We're under high load and we had to take down 2 servers for maintenance, leaving fewer WUs available.
Moreover, we as a rule avoid "busy work," i.e. WUs that we send out just to keep donors getting points but don't have scientific value, so there will be on occasion times when we run out of WUs.
We are also rolling out more GPU WUs in general as we're expecting continued growth in GPUs, at least for a little bit.

PS It's also important to know that generating new WUs, even when the science is done, just takes a long time unfortunately, typically 4 to 8 hours depending on the number of WUs being built.
