There is a testing batch out at the moment but I don't know if this is going to lead to main site work or not.


This new test batch, is it just more penguin food or is there some hope that we might see more Windows work before the Sun burns out.

I don't know about everyone else, but I have been crunching for WGC on their Open Pandemic COVID tasks. It seems like a good cause now that the Linux work here has dried up for the time being.


I’ve also been running OpenPandemic, alone with the odd WU’s from the African Rainfall Project.

Hello, did everyone go on Summer vacation, or is it just a total lack of new work that keeps anyone from posting.

Thanks. Hopefully I can shepard these two along and get them completed.

Is batch 871 still open? I just received 2 Wu’s (both _2s). They have failed on 2 other machines. They must be 3 or 4 months old. Are they still needed an wanted.

Any sings of new Windows work? I've just about finished those few from 2 weeks ago.

Now it's time to wait for more tasks.


Hopefully it won't be 3 or 4 months again.

I now have about 50 zip files that I can’t upload. I am suspending the 8 CP Wu’s running on my 2 machines until they get the server problem sorted out. Back to Rosetta and WCG.

The server down at the bottom of the planet is being attacked by thousands of Windows computers, and is getting a bit battered and bruised.
It may take some time to recovery, so Patience.

Ommmmmm ...


it might be a good idea if everyone reading this was to suspend uploads for a day or so, so as to take some of the pressure off the server while it gets caught up. Nothing will be lost.

The year long deadline may be partly historical. Back when this project started the slow computers (1.2 GHz) single core machines took 8 or 9 months (running 24/7) to complete the very long 160 year models. They needed the long deadlines. Now, not so much.

[quote]The "BOINC deadline" is long to prevent cpdn from hogging the processors, when other very much shorter projects are run at the same time.
This has been posted about for years.

A shorter deadline, something on the order of 4 to 5 months, would seem to be in order as that seems to be how long the Researchers are willing to wait before they close the batches. There is no sense in running models that no one is ever going to look at because the batch was closed by the time you finished it.

I am uploading two zips now. They are a bit slow at 50 kbps, but at least going.


Did they ever finish uploading and clear? Many of mine have reached 100% only to stall there and then drop back to 0%.

I assume that they are being done on laptops, which is the wrong place to do them I believe.

Better a reasonable time limit of 60 days (or 30 is OK with me).


I STRONGLY DISAGREE! I have been running CPDN (almost exclusively) for more than 10 years, since the days of the BBC experiment. I have over 20,000,000 credits. All of this work has been run exclusively on laptops.

I see what you mean. I just checked my RAC and after about 4 months of no work for Windows my RAC is down to 6.3. I hope they fix this before all the Windows people lose the right to post on this site.

There are no Windows tasks (wah2) at the moment, and none on the horizon that anyone knows about.


Though as I posted a few days ago,

#869 Micro-batch of 15 pnw tasks went out on the 29th April.


Sometimes these micro-batches are the herald of a larger release though I have seen nothing on the moderator communications to suggest this on this occasion. Three of the fifteen have completed. The other twelve have all gone to a machine with an average turn around time of 65 days so even if it is the herald of a larger batch we may have to wait a while.


There should be some way to better spread these small test batches (if that’s what this micro-batch was) around so that they don’t all get sucked into this kind of black hole machine. Otherwise this will become more and more of a problem as processors get ever larger numbers of cores.

FYI the 3636 second is the standard 1 hour back-off
18) Message boards : Number crunching : What is "HadAM4 at N216 resolution v8.52"? (Message 62321)
Posted 20 Apr 2020 by Profile JIM
Post:
This is apparently the current work unit, and the last one I ran, but don't see a description for it.
But before taking resources off of coronavirus, I am wondering what it is?
The files include "ozone" and "solar", so it could be important in those areas.


HadAM4 at N216 resolution v8.52 is the new Linux only model. From what I’ve read it requires a lot of RAM (about 4GB per core) to run well.

And someone has returned a WAH2RI task" How long is it since any of them were sent out???

Looking at tasks for my longest continually running PC, finally retired last fall, the last batches issued for RI might have been Oct 2016. So 3.5 years ago.


Even my atom powered netbook would have completed those tasks in under six months!


Most likely someone reactivated a very old computer that had been sitting in storage for a few years. I supposed it would be possible to pull up the trickles and see if there is a 3+ year gap between 2 of them.

Just done my daily check of the status page. Number of users in last 24 hours shows Linux only three behind the windows tasks despite the, "number of tasks in progress" for Windows being about seven times as many as for Linux. I am guessing it must mean a lot of those windows tasks are never going to be returned.


I’ve known that for years. Most of those “in progress” tasks have been lost in ways that the server never found out about and will never be completed. With no significant new work for Windows in months just about everyone with running Windows tasks has finished them.
