Message 1308298 - Posted: 21 Nov 2012, 10:30:54 UTC

When I got up this morning I found that my main cruncher was listed on my SETI account page as having >700 abandoned tasks. However, when I checked the PC there were no abandoned tasks and those marked as abandoned were still being processed and the PC was happily crunching away, ie it had not suffered a GPU crash overnight. I have since forced the PC to connect to SETI in an attempt to synchronise the two lists, but to no avail, though I did manage to connect and to download another 20 tasks for the PC.

Help! What should I do? What will happen when I return the >700 tasks which SETI for some reason thinks are abandoned? Should I manually abandon them?

This has never happened to me before.

I had that a week or so ago too, and the abandoned time was mid way between scheduler contacts,

Just Reset the Project on that host, then repeatably ask for work until your tasks are resent,

Happened to me twice already since the troubles with scheduler began.
First time I got 900+ tasks nuked and a week later another full cache of 200 (including 100 astropulses).
Always happened when scheduler requests were repeatedly timing out for a while.

Just another normal S@H operation, I'm afraid...

You should abort all those ASAP, as they will get ignored!

Just been informed it has happened to my sons machine; Host ID 6714690.

No apparent reason, he was out and the machine was unattended when it happened.

Thanks Claggy, just reset the project as you suggested. Shame about the 780 WU though, with the current limits it will be a while before I see that many again. Just to add insult to injury, the new WUs that i am getting are all shorties and are being crunched faster than I can get through to the server to replinish them!

Had the same thing happen on two of my machines since the outage yesterday.

I almost wonder if it is deliberate as a way of clearing all the ghosts off the system more quickly.

Nope, it was occuring long before the they figured out what was happening with the database.

I've had 200 so far declared abandoned.

On my sons computer about 130 of the 160 tasks dumped, were new tasks only d/loaded a few hours before.

Well the knock on effect of the 760 tasks being abandoned was that I was only able to get 100 replacements for my GTX460. These were mostly shorties and at 2 every 4 minutes each did not take long to dispose of. I have 3 of my machines set to only connect to the internet from 7pm-7am to keep the university happy (they complained about excessive bandwidth usage), and there is no way 100 tasks will last 12 hours.

Therefore I have had no choice but to put my most pwerful system (GTX460 + 4 CPU cores) onto Einstein until the current issues are resolved. My other three less powerful systems will stay on SETI as 100 WU lasts them a reasonable amount of time.

Be careful with that - Einstein GPU tasks need more data per hour of crunching than SETI tasks do. And the Einstein CPU tasks - in particular S6LV1 - do a very big initial download, though they don't need to repeat it very often. Your university might not like it if you time the switchover wrong.

Thanks for the advice, though I knew that. I was already running Einstein on the CPUs having not had any SETI CPU units since the abandon tasks fiasco, so only the GPUs was an issue. I took use network off preferences to always, got 60 Einstein GPU tasks, allowed some to download to keep the GPU happy until 7pm, then reset use GPU to based on preferences so that the remainder would wait until 7pm to download. Seemed to work OK.

I just got my first set.
You just need patience.
