Will this finally get new work from the project? I havent seen a work unit from this project in years, but watch my rank fall everyday.

No. BOINC versions have nothing to do with it.

There's only a few research groups that use BOINC to get extra info for their work, and everyone seems to have stopped this aspect of their work, possibly because of the extra restrictions on their work places due to the pandemic.

With tens of thousands of computers waiting, and only two-three thousand work units at very irregular intervals, you need to be very lucky to get any.

Note while waiting there are many other deserving projects that would love to have your support and clock cycles.

Feel free to pick a subject area that "speaks" to you. Math, Medical or Biology, Astrophysics, Computers and Games, Physical Science,

Thanks

And while weather rather than climate there is the Africa Rainfall Project with World Community Grid.

This is one of 20 projects which I contribute to, but only 16 are actively producing work (and of those 4 not producing work, Seti admits it is shut down). The remaining 3--including this project--just never do anything but defer communication. I am not new to all of this, and almost a decade ago I was turning in serious credits for this project. Then the work just stopped coming.

I recently wrote my own stat page to track my projects because I disliked the ones available. Thats how I noticed that 3 of my projects might as well be as dead as Seti since they never do anything.

The various academic institutions around the world that work on climate science do much of their work probably most of it on supercomputers. There are specific things they send work via Oxford to crunchers for. Sadly neither the moderators nor the Oxford project people know when their services will be required more than a week or two in advance typically.

It is likely that Covid-19 limiting the number of people who can meet up face to face has played a part in the lack of work. At the moment none of us know when the next work will come. Sometimes main site is preceded by work on the testing site that some of us do but not always and work on the testing site does not always mean it is shortly followed by main site work.

Another issue is the type of work it will be. In the most basic form, the question is Windows or Linux?
The Windows work is fairly uniform in its system requirement, but Linux is another matter. Memory and cache play a large role in how many you can run.
So you really have to plan for the worst-case, and set your machines up accordingly if you want to get the first ones to work properly.
(We can't select of course.)

While waiting for WUs isn't it possible that some improvements are made?
Shorter deadlines, being able to select tasks, check for 32 bit libs for Linux, clean up ghost WUs, better communication......

Different group of people doing the two jobs and programmers are in short supply.

I don't know details but I doubt if Sarah, Andy and the others are sitting idle at the moment. All those suggestions have been made a number of times in the past.

And almost as difficult to get a w/u for. There are a few now and then........ and there does not seem to be a status page showing if there are w/u's to be had. Or have I missed it?.

A bit late picking up on this, but 10 years ago is about when Oxford stopped running the simple model that was being used to accumulate a huge database of general climate data.

Since then, the work has been provided by research groups external to Oxford, that had learned about the project from conferences, etc.
This work has used increasingly more complex models, and has been mostly about attribution studies.

There isn't as much data needed as before, so a computer needs to be just sitting there waiting for work, and not busy running other projects, with just the occasional look to see if there's any climate models waiting to be run.

Climate Attribution Studies

Attribution of recent climate change

What is Attribution?

Since it appears that we have all the volunteer's needed to do a smaller number of "Larger" CPDN Tasks the choice is for the volunteer to make.

1. Load other projects at a lower priority to fill your System when CPDN is empty on tasks (and maybe miss a stray CPDN task being resent after failing or timing out)

2 Have your system empty and ready when the stray CPDN task or small test batch comes available. You will use less electricity, but accomplish no science while waiting.

Both are easy decisions based on the volunteers "Wants" and or "Needs"

I seem to be able to consistently run 6 of these. On a multicore computer the secret is to go to the profile - default, home, work or school the computer is using, click on custom profile and then up the number of concurrent work units for the project from the default of 1.

(Took me a while to work this out!)

Wow, Thanks for that info. I had not found those custom/home profiles per device. I now have as many ARP's as I want.

With the demise of seti and sparse w/u here on cpdn, WCG has some interesting projects.

Altho if seti had found a signal ............. still my favorite.

Just an FYI, the ARP tasks hate SMT and eat L3 cache as much as CPDN N216 tasks. So do one per core or 2MB of L3 (which ever is lower) for best turn around times.

Yep, noticed that. Combining the two with some 216's from testing certainly slows things down.
