BOINC 4.25 is now officially released; is CPDN ready for 4.25? Or do we still require 4.19? (I hate to run "old" software on my computer).

I think that unofficially it's ready for Windows, using hadsm V4.10.
The trickle server will tell you, and as of 5 minutes ago, it still said 4.19.

I havn't had any problems with 4.25 and it has been running about a week. It should not kill your old workunit on upgrade and the new 4.10 app is properly signed to run with the 4.25 client.

BOINC WIKI

BOINCing since 2002/12/8

I am already working with (beta) BOINC client version 4.62 and that's working, already two weeks now, very good with cpdn so I think 4.25 will not give any problems so far.

Well I tried to install it but it said to uninstall the old version (4.19). If I uninstall it, it will delete everything!?

Just copy the entire BOINC folder to another area of your hard disk first.
THEN uninstall, install etc.
If this fails, delete the contents of the BOINC folder, and COPY back the backup.
Then you can have another think / ask again.

Thanks for the replies. My current WU will complete in a few days; I'll wait until that is done.

How can I prevent a new WU being acquired before doing the 4.25 upgrade (but not prevent trickles being sent, and the completed WU results being uploaded) ?

You could set the space allocated so that a new model will not download. However I don't see why you don't let it download a new model and start crunching it. Upgrade to 4.25 early in that run. It will probably be ok and no time lost. Even if something does go wrong, you don't loose much and possibly only the same amount lost as if you stopped crunching.

I finished a model yesterday, and switched to 4.25. It's crunching OK on the new 4.10 model, but clicking show graphics doesn't do anything. Any clues?

I tried installing 4.25 on one of my systems this morning. After some password related tribulations on the service install I finally managed to get it going.

Graphics display worked intermittently for the Sulphur cycle alpha trial, and if the graphics window didn't display the option was no longer available for the model.

Things were definitely worse on HADSM3 4.04. Although the graphics window never appeared the hadsm3_4.04_* program started using the 25% of CPU time it normally takes on my system with graphics displayed. The only way I could stop it from doing that was by reatarting the BOINC service (suspending stopped the model from running but the invisible graphics window continued using its 25%).

Thanks for the tip, Thyme.
I'd noticed the windows process taking a little time. Guess I won't try the graphics anymore.

I couldn't wait for the current WU to complete (it's still about a week to go), and since 4.26 is already available, I installed it.

The whole process just took a few minutes; saving the BOINC folder, uninstall 4.19, install 4.26, then restart BOINC.

No problems at all; it is happily crunching from the point where it left off on 4.19.

On my machine, BOINC 4.25's GUI failed to communicate with a nonexistant service on a clean install, and wouldn't add any projects. But the command line client seems to work okay.

For the time being, I'm going to stick with 4.19 until 4.25 is "fixed".

Hello Crandles:
You and several others (Thyme Lawn, Saeger) were very helpful in setting up a new WU in advance of a vacation here.
I have completed one application and it uploaded successfully. I was waiting to suspend BOINC to upgrade 4.19 to 4.25, but BOINC very quickly started a download of not one, but two "names" under the application 4.12.
I suspended BOINC and upgraded, but one of the names is under "ready to run" mode.
Will these names run sequentially, i.e. BOINC will upload the completed "name" then start the second?
In Preferences, it appears that there is an opportunity to switch between models/names to get coincident work done. Is it possible to work simultaneously on these "names"? Or is the second waiting for results of the first? Otherwise, total hours to completion is approx 1360.
Given the CPU time availble, maybe we could add another BOINC program?

&gt;the application 4.12.

Not sure why it did that.

Since your celeron processor does have hyperthreading, it should work on them sequentially. There is some advantage to working simultaneously if you have 2 processors or a hyperthreaded processor. Otherwise it is a disadvantage working simultaneously eg cache memory split between the 2 models.

The opportunity to switch in preferences will give a hour of time to one project then an hour of time to another project. You may as well work on just one model so that 1 gets done in 680 hours rather than having to wait until 1359 hour for the first one to finish.

If 4.13 or later is out by the time you finish the first one, you may then want to scrap that second model, but for the moment it shouldn't do any harm to leave it there.

Actually, there were two 4.10 apps on the previous run, and I assumed that BOINC, being more clever than I, eliminated the "ready to run" app and downloaded a more appropriate (later?) model. I hope that there isn't one of those now "in limbo" as noted by Thyme Lawn.
&gt;
Thanks Crandles.&gt;
