It's best to finish all GPU tasks before upgrading.

You don't need to uninstall anything: you won't need to reinstall any optimised apps.

Drivers are a movable feast.

Richard, what benefits would 7.0.56 give over 7.0.28?

It always says that for non-recommended Boinc versions, But Boinc 7.0.56 is a Release Candidate, and is somewhat more finely polished than Boinc 7.0.28,

There's a bug in 7.0.28 where it doesn't identify GPUs that are suitable for OpenCL AstroPulse. I have one box formerly on 7.0.28 that would consistently download an OpenCL unit, then report that there were no available compatible GPUs and abort it, then download it again, ad infinitum. 7.0.56 fixed this, so this is one reason to use it.

Also 7.0.56 seems to have fixed the bug in earlier RCs where it would abort CUDA units after a few seconds indicating that they were taking too long! So far, it seems good.

On the other hand, some of us read that as USE FOR TESTING, and do our best to get the bugs out before the rest of you see it.

Sorry Chris - but a quick scan down BOINC 7 Change Log and news got me to well over 300 changes between 18 May 2012 (when v7.0.28 was released) and now. I didn't feel like writing a precis over the weekend, but I've tested pretty much every one of them (and reported a good few bugs, old and new, along the way). My judgement is that v7.0.56 is pretty close to ready, and I'd choose that one over the next couple: I actually persuaded David to tackle a bug report of mine from five years ago (#588), so that'll be a couple more iterations before we get the bugs out of the fixes.

I see a lot of bad advice on these message boards, but in this case, I don't think the charge is justified.

richard

the card i am installing is a gtx680, what i am currently is onboard intel hd4000 video. with this information IYO do you think upgrading to the new version will be worth it?

You need to install .56 for sli setups, the .28 wouldn't use more then one gpu for me.

Oh dear. What a lot of scrabbling for answers.

@ Bob,
As has been posted several times over the last 48 hours, there is a problem with the step-transition between .28 and any later version. Unless you want to be locked into v7.0.28 for evermore, you're going to have to get over it sometime. The errors are just for work which was issued under the old version, but crunched under the new version. You can avoid them either by running down your cache first, or by resetting the project after upgrading.

@ Luther,
You've found one of the many improvements. You could run SLI (two identical GPUs) under the old version, but sometimes you had to force BOINC to use them both with a configuration file. You'll still have to do that with unmatched cards, but less often.

@ trader,
I see you've written nearly 40 posts (and I know at least one PM as well) since you re-started crunching after a four year break. I'd slow down a bit. As you're finding, the new BOINC and GPU crunching is very different to what you remember. Do a little more reading, and a little less writing, before you decide whether to upgrade BOINC. And start by reading the reply to Bob above.

I was going to reply but I see Richard has already done so.

To reiterate the recommended approach when upgrading from a earlier (as in 7.0.28) version is to finish off and report your GPU work first. Personally I usually run the machine dry before upgrading but that's just me.

I am running .56 on one machine and have .52 on a bunch of others. One of the advantages of the current version is support for the Intel HD graphics built into the newer i5 and i7 chips.

Several advantages have been mentioned for .56 vs. .28 - here's another. I'm running it because you can run multiple instances on the gpu without using anonymous platform. That helps on projects where anonymous platform is discouraged (like Beta, WCG, Milkyway), and would help those that are unable to install the lunatics apps here on main. This version is stable.

And now there's a .57 to test. Installed OK, too early to say if there are any problems yet.

Well, it won't fix the crash my client had the other night, as that one is as much a mystery as how the connection to the forums continued with the network being disabled. ;-)

Do you know if 7.0.57 has this fix in it?
I don't see it listed yet, BOINC 7 Change Log and news
I find it interesting the first item missing from the Error reports is the Time...

I'm waiting for the Macintosh version before I put up the change log.
Rom just emailed that he'll release a new version tonight. So it may all be .58

The fix you see there, is for applications, not for the client. The BOINC API is used in compiling applications, not the client. See http://boinc.berkeley.edu/trac/wiki/SourceCodeGit#Sourcecoderoadmap and for the actual fix https://github.com/matszpk/native-boinc-for-android/commit/8c8ccabee7b6b3f34c2bae0f2d72a49f2d8107da

So, it appears you are saying the applications will have to be recompiled to incorporate this fix?
