The server upgrade is indeed so we can support ATI GPUs (as well as Nvidia - as the server code is a bit old).

We have a working CUDA app, so after the server upgrade we'll be putting out our application with CUDA support and testing that.

When we get a working app for ATI GPUs (AFAIK we haven't had any code shared with us, so either someone will be nice or we'll develop it ourselves), we'll update the application with that.

That surprises me - Cluster Physik has mentioned in several threads that he's 'ready to go' with the ATI app pending the likelihood fixes - have you tried contacting him about exchanging code?

When I installed 6.10.0 on my laptop, it keeps setting number of CPU=0 no matter what I set in preferences. anyone else seeing this behavior?

Yes, Cluster Physik has been very forthcoming. I hope they can track down the source for the ATI app so we can get that repackaged as a standard project app.

I think Anthony (our new student working on the GPU applications) is in contact with him so I'm sure they can work something out.

That "ready to go" applied to the (now dead, it seems) GPU project variant. The "normal" double precision version runs for half a year now. If the project wants, they can simply distribute it.

I can give them also the code, but unfortunately the GPU stuff is not easy to understand C like code (as Brook or CUDA), but some quite long GPU assembly (as I had to work around some deficiencies of ATIs SDK). That is a difference to the GPU project variant, which is pure Brook+ (single precision support is better). Nevertheless, Anthony could compile Linux versions with it, if he ports the host code part, the GPU part doesn't need adaptions.

But I have to find some time for code clean up first. There is quite some dead code in the files, after all, it still bases on my 0.07 version. If the project decides to dump the possibility to run more than one WU per GPU (according to DA he wants to add that possibility to the client for both ATI and nvidia) one could even remove most of the synchronization and scheduling stuff, making the Linux port much easier (maybe even a simple recompile). And the problems of the newer drivers required for a SDK1.4 version (needed for official multi GPU support, I use a modded selfcompiled v1.3) with WinXP could also spoil the party.

Message 29649 - Posted: 23 Aug 2009, 1:37:41 UTC - in response to Message 29581.  

I tired 6.10.0 tonight and couldn't get it to work. It would run either AQUA CPU or MW GPU but not both at the same time. It did load a full 48 unit cache for MW but all units went into waiting to start. If I suspended the cpu task it would start and run fine but would once I resumed the cpu again it would go to waiting.

Is there a setting I'm missing or something I need to do to get both to run simultaneously?

Tried 6.10 myself and it ran nicely but would not request GPU work, even with debts being manually set and forced updates. So, back to 6.4.7.

With the absolute FUBAR of a work scheduler with the later releases of BOINC which includes 6.10.0, I'm back to 6.4.7.

I observed, with 2 AQUA wu's suspended and AQUA itself suspended and 3 SETI wu's suspended and SETI suspended, 6.10.0 would still not request MW work, even with manual updates. Surely they can't be serious!

Now guys you were supposed to say; "You idiot if you change your settings to .... then everything works fine!"

You're absolutely no help! I know it must be something I'm doing wrong because it couldn't possibly be BOINC.

Actually I'm wondering if the project has to do something to tag the wu as GPU so BOINC knows how they should be handled.

Beg or bribe Anthony to release those GPU apps as fast as he can. ;)

I tried the 6.10.0 on a few Box's & it seemed to work for awhile. But then all of a sudden it wouldn't call for work anymore from Milkyway no matter what I did so I went back to 6.6.20 again on those Box's ...

yea
lol me found the same and put back 6.4.7 version
And also split my cards over 2 pc's because when i run them both in same machine my rac drops to 60% cause lack of units :)
rac back to abnormality and rising
Its new, its relative fast... my new bicycle

Well it seems pretty, much clear to me that with so many people still having to use 6.4.7 (including me) despite dozens of boinc releases since then, that they are really meant as upgrades for the CPU guys not GPU crunchers. I don't see the situation improving until there are dedicated GPU workunits and apps. Having said that though the number of cpu crunchers out there compared to GPU ones, means that the majority are being catered for which I suppose is fair enough.

Edit - The release history page of Boinc has many references to GPU's but obviously they haven't been too successful otherwise we'd use 'em!

Message 29680 - Posted: 24 Aug 2009, 16:11:21 UTC - in response to Message 29673.  

maybe i have an error in my script but as i use my old update script the server responds that its too soon and let me wait another minute longer xD
so instead of 1 minute it started getting units every 2 minutes or so :D
and then wonder o wonder just give me 2 units ......

Its new, its relative fast... my new bicycle
