My other question is: why not keep acquiring and crunching more data while start processing the old one? The sky is so big.
Because they don't have manpower do to both at the same time. Keeping a boinc server running at setiathome scale needs lot of work. And doubly so with all the problems we have had since December.

Part of the pressure may well have been precipitated by the database running out of RAM? There will be a big jump needed in effort and manpower to upgrade to new hardware to fix that...


And then there is always the non-science educated Bean Counters who apply unreasonable pressure to have their bean counting arbitrary metrics massaged to boost their non-scientific bonuses?...

And all too often sadly, the Bean Counters never account for the highly valuable value of continuity and loyalty...


All a game and all conjecture.

Meanwhile, s@h has already achieved groundbreaking/spacebreaking fantastic results and started a whole new way of planet-wide distributed computing.


(Special note: This is all my own uneducated personal prejudice and random guesses!!)

. . I am not surprised by his message. He and others have put a great deal into all of this and endings are painful. But I believe that Keith's sentiment was that with the plug being pulled on the volunteer participation the staff will be less than motivated to upgrade or improve the operations of that part of the project. There will be no time or money to 'fix' anything on this side of things.

Exactly. Not questioning the time and devotion to the project Eric has put in over the years.

Finally able to check out Tasks again.

Of all of my Validation Pendings, 19% of them are over 28 days old.
An almost 20% reduction in the size of the database would have been very helpful.

. . Well if it is not difficult to do (IF?) then it would be advisable to implement the 28 day deadline (or thereabouts) and maybe return the server limits to 100 per device for the remaining couple of weeks to give the backlog a chance to clear before shutting down. Maybe even reduce deadlines to 14 days since it is such a short term thing now. It would be nice to see things clear up before the plug is pulled. I say this because the validation backlog has passed the 15 million mark.

I suspect there are a number of people who read the first few words of Eric's announcement and turned their computers off. We have seen this every time there has been a glitch in tasks being distributed, some folks assume they have to connect to the servers to be able to process the tasks they have in hand.

Yep.
Deadlines- 2 Weeks for all WUs, inc AP. 3 days for re-sends. Why drag this out for 9 months (or more)?

Appropriate thread.

Changing the deadlines has no effect whatsoever to the assimilation blockage.
Since the Assimilation backlog is a result of the database bloat which has been caused by the increase in Quorum to deal with the RX 5000 issue, it will help with with Assimilation backlog.
Fix the cause, and everything else that is affected will be sorted out as well.

Remember few weeks ago, before the announce of the S@H hibernation, when i propose to send the resends to the fastest APR hosts to help to reduce the DB size?
There where someones who said that was wrong and that will never put to work.

Ok since we can't access the server code, we develop an option in the controversial spoofed client who does exactly that only using the WU received by the client of course. But the regular client could do the same. Just by add the related code.

This is an example of it working on a totally random WU

As you could see the WU was siting around the DB from Jan 10.
My host receives the resend today and already crunched it, so the WU is ready to assimilate and cleared from the DB in minutes after received.

This is an example of a single scheduler call, from my own host not one of the fastest on the SETIverse, so you could extrapolate and check the effect of that measure if 100's rely fast hosts where doing the same. This is a random scheduled task too. I will leave to each one do the math and find it's own conclusion.

BTW I'm not trying to start a new fire, just presenting the facts and the data to corroborate, maybe that could warning the others there are some around who knows a little about the way the computers works, has the knowledge and are ready to help.
