Have you also got "Jump to first new post in thread automatically" ticked?
This, plus the 2 that you mentioned, have worked for me for years.

Batch 833, of 500 "CA camp fire attribution" models have shown up out of the blue, but they're nearly all gone.,

I didn't see anything on Project stats, just a private list, so I'm going to go and whinge about it.

It does say "minimum requirements", which covers things, but, as I said in my previous post ...

Yes, it is getting a bit old.
Perhaps like saying that you need a 2 horse bucggy rather than a one horse, when they've all been replaced by this new fangled automobile. :)

I might try a re-write, and see how "them upstairs" feel about a change.

Androids are never going to be used on this project, and for Linux it's best to have about 2-3 Gigs of ram per core for the Met Office models.

For the new OpenIFS models, you'll need between 3 and 6 Gigs of ram per core.
And there's been no sign of them since we ran the big event a few months ago during the the introductory conference.

The place to watch for new work is the New work thread in Number crunching, (which can be a bit late by the time you hear about them), and the Project status thread.

There were 600 Windows units less than 24 hours ago.
They were for batch 832, cam25, Wah2.
Took less than an hour to drain the hopper.

You better give that computer of yours a good talking to. :)

Apparently we're already being asked to reduce gas .
A different type, but strange how we talked about gas, and this shows up:
Canberrans asked to do 'heavy lifting' in battling climate change including give up cooking with gas

The problems probably lie in the decay rate, and in how it interacts with "everything".

e.g. CO2 is being absorbed by the oceans, making them slightly more acidic. This in turn makes it harder for shellfish / crustaceans to grow their shells, which will / is decreasing their numbers.

One option still available is the cache.
Set it low, to one or two, see how they go, and then decide if you want to continue with that type.
Not that there's going to be much variety to choose from.

There have been a lot of emails between the moderators and the project people about the changes, both done and missing.

This was one:

We have moved for the moment to a separation of different apps on different platforms, i.e. Weather@Home on Windows and HadCM3, HadAM4 and OpenIFS on Linux and then HadCM3 on Mac. Therefore the choice of which app a user will run now is pretty much dictated by what platform they are running. To move back to a point where we support all apps on all platforms will take significant work and in some cases it is not clear if this actually be possible.

From the point of view of W@H the app now no longer really knows which region of the world that it is running in a manner in which it would be easy to tell BOINC since we have the region independent app.

Therefore it just seems sensible to remove this feature for the moment, or rather not use valuable effort to re-enable at the moment.

When I then raised the matter of the big OpenIFS models, there was this:

Hi Les,

Yes I understand this and so will be looking at what are the minimal requirements and setting as appropriate when launching.

David


So they are aware of the issues.
I think that the main thing that crunchers can do, is to pull up their socks, roll up their sleeves, grit their teeth, and, in a lot of cases, get their computers up to acceptable requirements.

It's instructive to occasionally look at the list of users, with no name in the search.
This takes you to the last page, of most recent sign ups.

I've seen a computer with only a gig or so of ram, an Acorn, and a Darwin machine with 16 processors, and only 16 Gigs of ram.
Quite apart from all the obvious spammers. :(

The way it is shown now, is the way it's going to stay.
The project people are going to do things differently. :(

I missed those batches, as I was running test site stuff at the time.

There's a link on the project's front page about this new project, although not much more than has already been extracted and posted in the News thread.

Even the moderators don't know about this yet.
The early news post was probably to test the new "changed and improved" News section.

When there IS some info, it'll get posted.

Andy has said that there some changes coming.
This is the one of most urgent concern:

The project is going to switch from: https://www.cpdn.org/cpdnboinc/ to https://www.cpdn.org/.
A large number of the links have already been converted.
The main one is the BOINC project link.
I have requested the link to be changed in BOINC, I think this will be done by tomorrow. ***
This change will however cause the 'This project is using an old URL' message in the client.
Going forwards the https://www.cpdn.org/cpdnboinc/ will continue to work alongside the https://www.cpdn.org/ link.


Andy


*** "by tomorrow" will be the 12th. But this being about computers ....

I'm going to try the:
Click on the bookmark
Edit the url
Re-save the bookmark

path. I think that this is what I did last time.

Until Andy finishes upgrading the server, and fixing loose ends, people are going to have to struggle along with the old listings.

Post:
As has been said, CAMS are a pain.
The only real "cure" is to wait until a zip has uploaded, and then tries another upload from scratch.
At that point, assume that it got through the previous time, and Abort it.
Do the same for each of your 5 files.

At this point, BOINC should wake up to the fact that everything has "uploaded", and finish off the transfer process. Perhaps not immediately.

It's been so long since I had to do this that I forget the timings of what happens.
