We are planning to start a test of this new redundancy and validation scheme. This test will run in parallel with the main project, so hopefully we can avoid mistakes.


Whatever you do, do not change the homogeneous redundancy type while there are still work units in progress - The problems will be even worse than the discarded WU \'episode\'. I can think of at least one other project that had similar horrendous HR problems due to FGHR, and changing to CGHR mid-stream is really going to hurt.

5. I\'m finding many, many WU\'s like 4883478 that were previously cancelled with \"Didn\'t need\" that now have new tasks created today. Some are sent... many are not. Is this an effort to finish WU\'s that never would have completed? Was this purposefully done or just the WU generator doing it\'s \"own thing\"?


My only remaining pending WU that escaped the Zero Credit Axe is this one:

http://www.cosmologyathome.org/workunit.php?wuid=4880325

Note that it\'s partner in crime was flagged as \"Didn\'t need\" and then a new WU was created 13 seconds later! I live in hope that my last surviving WU escapes the death penalty ;)

Hi Ben,

As a long-time volunteer to this project, I thought I ought to make a few points on issues that you seem to have misunderstood.

For the avoidance of doubt, I stopped processing work for this project a few weeks ago, and it seems unlikely that I will return. I dare say that\'s not such a big loss to the project, as I was only in the top 10% of number-crunchers here - The \'big boys\' do the bulk of the work :) I am genuinely interested in the work that you are doing, but I feel that my efforts could be better used elesewhere.

As you know we went through some technical difficulties in recent months.


Those were human errors I\'m afraid. There were no technical problems, merely short-sighted quick-fixes that had far reaching consequences that should have been thought through before implementing them.

C@H is running smoothly


No. It isn\'t. Look at the horrendous HR issues that you have here for example.

some people were not awarded credit for their WUs in the course of fixing our code and the server/database issues


The credit is only a partial problem. You could easily fix that. Write another script to give a nominal credit to each discarded WU. The problem is that a lot of people put a lot of effort into processing work that although entirely valid was ignored. The loss of credit had nothing to do with \'fixing\' the code - It happened because the fix was wrong, not thought out, and when volunteers started commenting that their work was being discarded they were ignored.

We are also looking for a new person to continue the web development and screen saver graphics, since our very talented graphics designer (an Illinois alumnus) left to work in Hollywood (it was only a question of time...)


Hehe! Lets hope people like black and white movies ;) Comments about the \'new\' website have been well made in another thread.

To compensate we have been handing out very generous amounts of credit for our WUs in the past


A couple of points on this.

In the very early days, when WUs crashed just before completing or results were erroneously discared the credit was probably fair. It wasn\'t generous.

The other thing is that the whole credit level thing is a red herring. Credit doesn\'t buy groceries. All it does is give a volunteer some idea of how they are competing (yes, BOINC crunching is competitive) with others crunching the same project. Anyone who has crunched DC projects knows that cross-project parity is a dream.

Given that things look fairly stable now


???

Anyway, that\'s my view on things. It will be interesting (and possibly entertaining!) to see where this project goes. I\'m increasingly beginning to think that the obsession with credit is going to be the death of BOINC projects and that maybe we\'ll all end up crunching the old-fashioned way with DC projects. But that\'s another story ...

I wish we could get rid of the \"URGENT\" threads because ...

1) They are unusable for real, urgent, current issues because they are too long.

2) I\'m not aware that any action gets taken on posts to them, other than post being cut and pasted to other places.

3) It sends a message that you guys can\'t be bothered to read your own forums.

4) The urgent problems are staring you in the face. When a new thread starts and many users post about the same problem, that\'s urgent, so deal with. That does not mean cut\'n\'paste somewhere else.

How about \'Contempt\'? That\'s all we volunteers see around here these days. Might be nice to formalise the arrangement.

I see this forum is run by a bunch of iron fisted ******** that can\'t think beyond their own narrow mindset. I guess it\'s a waste of time visiting this forum since the one thing I can count on is having my posts deleted.


I had one of my posts uprooted and dumped, without context, into another board and thread.

My problem is, I really like this project. No, really I do. I\'ve been along for the ride since the beginning. And it\'s been a really bumpy ride at times. I leave, then I come back.

However, I\'m feeling that with no input from Scott or Ben that I\'m wasting my time. I don\'t mind throwing away massive amounts of tiderc (deliberately reversed to avoid waking the mods up), but I wonder what happened to the Science Part.

There is at least one good mod here. Actually, maybe just one. You know who you are ;)

I should have kept quiet ... Most of my pending WUs have received the grand total of zero. I expect the last three stragglers will get zapped too.

Great. Smashing. Super.

Hahahahaha! Very funny guys. No stop, really, it\'s just *too* funny! Not often that I see a project granting so little - Keep it up, you\'ll soon be down (and out) with Gerasim :)

Best go and top up my credit at a high-payer like Seti ;)

Well ya\'ll are still on to something as the resends are about 80% of what I get....


Interesting. My few remaining stragglers are all resends, and all on my oddball Celeron (all other hosts have been dry all day).

Just looked at recently completed tasks and they were all resends. So, one specific type of hardware, and all resends - It\'s a cleanup operation with some HR \'factors\'.

Was just about to go NNT and a \'fresh\' resend just landed in the Celeron queue.

This is weird and frustrating.

Well, I\'ve got 5 XP boxes on Cosmo. Looks like the only box I get any work on is Ye Olde Celeron, and that\'s not enough to keep more than half a days cache. Oh, just had a look, I seem to have snagged one WU on my slowest P4 about 6 hours ago also. Other than that I\'ve got a few WUs from days ago hanging about, but basically I\'m dry on 80% of my hosts.

See this thread that I started a while ago, it\'s the same problem:

http://www.cosmologyathome.org/forum_thread.php?id=503

I had another sleepy WU on one of my hosts today and aborted it as these WUs take ages to complete as they spend a third of the time thrashing the HD.

As for \'replacing\' the PC, why not leave it crunching? My old 1.8 still turns in 600+ credits on this project:

Please report any bugs you might find and give feedback about the look of the site.


It\'s deeply, deeply ugly. Looks nearly as bad as RCN and Suduko. Black websites are for trendy media companies, not for serious science projects.

I\'m looking at a skinny third of a screen (widescreen monitor), populated with salmon pink and white. I feel like it\'s 20 years ago when these visual \'treats\' were supposed to be \'clever\'. Difficult to read too.

I\'m not surprised that your designer left. I guess he/she didn\'t want to be associated with this crock.

Well, you *did* ask ...

I suspect it may be a local problem to your host


It was a different host the first time it happened - But I think I know what the problem is now ...

I started running this WU again today, and it\'s behaviour was the same. But, it stopped running properly when the memory usage got to over 170 megs. Once it got the that point the memory usage started fluctuating wildly, the disk was thrashing, and the page file usage was getting to twice the size of the physical memory. This host, and the other that showed a similar problem only have 256 megs of RAM.

Most Cosmo WUs that I\'ve crunched today have used between 70 and 100 megs of memory, so this one was exceptional.

After over 5 hours run time I aborted it. Intersting to see that it only used 3.6 hours CPU time while running - The rest was wasted in page file swapping :(

Anyway xPOD has the WU now on a machine with 1 gig of RAM :)

I had one of these a while ago and just aborted it as I thought it was a one-off or a host problem. However, I now have another one:

wu_060308_031223_1_0

http://www.cosmologyathome.org/workunit.php?wuid=3362212

It ran OK for a while, but then just went to sleep! Virtually no CPU usage, but a lot of disk activity. I suspended the WU and let others run, but have now resumed this one and forced it to run.

It did nothing for a minute or so, and then the progress indicator dropped to zero and started running again. Everything seemed OK, but I\'ve just noticed that it\'s fallen asleep again - It\'s running about 18% CPU and hammering the disk but no increase in completion percentage.

I\'ve suspended it again for now as it has over 3 hours crunching on it and I don\'t want to throw the science away :) Would be nice to let it complete, but I can\'t leave it unattened and wasting host processing time.

Anyone know how to keep it awake long enough to complete? My guess is that the memory usgae is now so high that the host is spending all of it\'s time page-swapping.

It\'s XP32, BOINCmgr 5.10.45 and has crunched many Cosmo WUs and other projects happily for months.

Hi guys,

Given that Cosmo has been so stable for a while now, I thought I\'d start a new thread rather than dredge up ancient ones :)

Basically, I\'m getting \"No work from project / No work sent\" across 5 hosts, and have been for a day or so now.

A few WUs have drifted in on a couple of hosts, but I think you have a problem. Loads of work available, but not getting much here. Not a problem for me, I\'ve turned on backup projects, but it\'s a shame to think of all of those WUs waiting to be crunched and not getting out :)

The Forum & Account Pages seem to be much faster after the work done by Scott, but the same old problem with getting work still exists. I have PC\'s that still have no work on them, they keep calling for work but get every response from the Server in the book except the proper one > Work Sent ... :)


Yes, the web stuff is really lightning fast now :)

I seem to have picked up work on all of my hosts (Windows) without much effort. Only set them to allow new work a little while ago. Also my validation backlog has almost cleared now :)
