Too many failures on Tsinghua Nano Tech Research. Have set it to no more work until it improves.

The work units take hundreds of hours and then fall over. It's very disheartening.

I am wondering why Work Unit 9286409 could not be validated after meeting quorum of 2, the work unit was returned back on the 29/11/13 and ran for over 1,200,0000 seconds (over 330 hours).

Also This Work Unit dates back to 25/11/2012.
I returned my work unit on the 24/11/13 (running over 800,000 seconds), there are 2 other successful results still waiting validation from October 2013 and April 2013.
Still we await validation and new work units keep getting issued.
What is wrong with this work unit?

I would like some return for the hundreds of hours I have invested in these work units, Please?

Wow, I just got one of those LONG work units... 48 hours and still only 11.47% done... no other CAS tasks sent to any of my machines...

And I see so many times these long WU's marked as invalid too! I'm tempted to abort it...

Is any project admins around anymore?

looks like these WU's set to need 6 successes before points awarded... the one I am working on has had only two successes so far and looks to take from 7 to 14 days to run...

We will see...

Well, 4 days later, 20% done... so looks like take 16 more days...

And then if it doesn't error out, I have to wait until 3 more people run it as well for points...

Sigh...

20 days to run a task on a 4.5GHz 2700K is an awful long time. It seems this sort of WU is contradictory to the BOINC concept of many smaller WU's passed to many computers...

Everybody is subject to power glitches, storm glitches, and just about any sort of thing that can clobber a WU and WASTE weeks of work...

Oh well...

Hmm, obviously the minimum quorum isn't applied here... maybe the two completed tasks don't agree? Mine is 5Days-5Hrs and 24.5% complete...

The WU is http://casathome.ihep.ac.cn/workunit.php?wuid=9339591 and I am not sure it can complete before I have to go on the road again...

Oh well, we will see. I'm not the only one in this boat...

Would be nice if an admin would comment..
