Project Update

[kashi]

Urk, invalids, did they only start appearing in recently received tasks? I haven't had any invalids or inconclusives yet but I've only completed 97 tasks so far, 82 valid and 15 pending waiting on wingmen.

Hmm, I wonder if CFSW runs homogeneous redundancy. On one project that had HR I used to get matched with server type Xeons which returned work slowly and claimed low. Even though my CPU was virtually identical to a Q9450, because it was called a Xeon X3350 it got matched with other Xeons because I think BOINC used the processor name string instead of the vendor string together with the CPU ID, which is a more reliable way to match CPU types. Don't know if BOINC still works that way, I remember it caused invalid problems in the past on some projects with different CPU types that had the same/similar name string. If your CPU type was the odd man out in a quorum of 3 after an inconclusive match of the first 2 replications, your task would get marked invalid and you would receive no credit.

My current CPU is a Xeon too, a W3520 which is the equivalent of an i7 920. Maybe that's why I'm not getting any invalids or perhaps it's because I have a one day cache of CFSW work so haven't finished any recently released tasks yet.

Kashi,
You're absolutely right actually.  I didn't even look twice at the WCG Beta results.

I just know that i recently enabled Beta testing and assumed that the beta work units were all processed by the GPU for WCG.

I'm not quite sure how to explain my results... other than there must be some CPU thrown into the mix as well.

[kashi]

Yep you possibly received a few CPU betas. I must have received one or two also because my beta stats show 156 tasks completed in about 20 hours which is an average of 7.7 minutes per task. The longest beta GPU task I completed had a runtime of about 4 minutes and most were much shorter. Strange, I can't remember receiving any beta CPU tasks, maybe a few sneaked through or I had done some earlier when I first enabled beta and had forgotten about them.

Or perhaps they could have been trying to change the GPU tasks from CPU time to elapsed time and added a little runtime for the first ones they missed. Or something like that, it's only a GPU beta and still quite unpolished in some respects so little quirks like that are possible. It's certainly not going to alarm CPU only people, I've still got less than a day showing for beta for work that if done on my CPU would be almost Bronze badge level.

[Dataman]

One of WCG's problems is they are 100% date driven to release. They toss out 10K wu's and then put it into production. Most memebrs have no idea what a beta test is and just want a badge.

I do know one thing; since I shut it down yesterday morning I stopped getting invalids, inconclusives, errors and single quorum PV.  I rotated the farm to MW and Einstein. Shut down half the machine as it is getting warm here (88F yesterday).

:aus1:

[kashi]

Well I stayed on, I have suspended the 2 tasks with quorum of 2 I have in my cache just in case they get marked invalid which would cause my computer to become untrusted and all single replication tasks from then on to go inconclusive and risk becoming invalid. That could create a vicious circle. I have assumed the single replication tasks are OK if they don't go inconclusive as all mine are validating so far. When the periodical check of trustworthiness comes I may be in strife.

BOINC has wilfully disobeyed my resource share settings so I've set Docking to No new tasks for now and downloaded a few days of CFSW work to ensure I don't run dry again. Fingers crossed that it will soon be time for a Silver song:

And it's hi-ho silver lining
And away you go now, baby
I see your sun is shining
But I won't make a fuss
Though it's obvious

Greetings fellow crunchers

So far (knock on wood), I have had no invalids or inconclusives with CFSW, but I did have a outage on my computer over the same period when CFSW was having some glitches causing invalids and such.

Happy crunching

I only had one inconclusive but it is gone now and validated I think as there are no errors.

Hi all, I wonder if I could be so bold as to ask a few questions rattling around in my noggin ?

And I hope you'll excuse my noobish questions & if this is not the right place to ask or it has been asked before err sorry ;D   Questions like........

... I accidentally discovered WCG had a challenge issued by B@A ie: "One week Challenge" in Computing for Sustainable Water that finishes on 29/04/2012.  My question is, is there a central place on the board that one might peruse upcoming challenges for all Boinc projects between AA's so as to help the team?

&... I read somewhere that Kashi said there's very few people doing SIMAP  & then went on to another topic.  Err are we supposed to be doing SIMAP during non AA times? Again is there a way to find out?

Also... I too have now noticed 1 invalid and now 30+ inconclusive cfsw. Is there a way to stop the flow on effect as Dataman & Kashi mentioned, other than stopping?

And even....Kashi you mentioned "tasks with quorum of 2". I understand basically what it means but... is there a way of checking quorum while the task is on your system with out going to WGC & checking & re-checking in boinc manager one by one?

I have read so many posts and help topics that I have square eye's. There was nothing for it but to ask the good & cluey folk here at B@A. Stay tuned to this station more questions to come....

Thank in advance...(JugNut).......... err was this post to long?......

If you go to this forum: http://forum.boinc-australia.net/index.php?board=114.0 and click on the Notify button near the top right hand corner, you will be asked to okay receiving updates posted in there. Announcements are or should be made in there. Sometimes we forget.  

err was this post to long?......

No, it's just fine.  

Others are more expert on the other questions, so I'll leave it to them.

[Dingo]

I created a new Board in the Members Only part for Challenges and moved some posts from here to there.

[JugNut]

New ATI GPU beta's just started coming through.  Get em' while there hot...

[JugNut]

Thanks for the heads up Sean,

I've switched all pc's to HCMD2 to see if I can snag 1 more badge before they close shop. (not likely if there's only a few days to go)

Then i'll do the same to HFCC after that.

Just maybe if I max out the cache......... Oh well nothing ventured ect, ect.

Oh yea, I got a couple of Dengue's P2's also. Just 2 or 3 though.


Cheers ..JN..

Even though there's supposed to be 18 days left (now 15) work is already sporadic & hard to keep all core's active on both projects.  Even with a huge cache setting.

Maybe just a temporary run on WU's?

EDIT: Nope servers are down ATM

[Dingo]

Yes moved over to http://ibercivis.es/ till WCG comes back as I am out of work.

[JugNut]

Just before the outage one of my machines downloaded 57 HCMD2 WU's.   

Now my other 2 pc's have no work (at least as far as WCG goes).  What I was wondering is can I transfer WU's from one machine to another? 

Just copy the HCMD2 WU's across the network to the other pc's that have no work?  Is this possible?  Would it work without disaster?

Cheers ..JN..
