Probably after it's released. Official BOINC support for ATI is still in development.


Really ?

Just because stuff has been committed, it doesn't mean the support is finished. Likely, there'll be bugs.

Also, DA said back in February that ATI support was likely a month away. Rom said the same thing yesterday. We'll see how that turns out.

When MW will relased CUDA app, all will be clear, We will be able to do direct comparision ATI vs Nvidia....

However, making cuda app takes sooooooooooooooooooooo long.....


I attached MW_gpu 3 mouths ago. I have ever recieved any CUDA WU. And now My account of MW_gpu has been deleted by server. It denied my login and refuse to accept I reattach it.......

I think CUDA is an impossible mission for MW_gpu......

For one, the CUDA application isn't even finished yet, so there's no way you could've downloaded CUDA work from it. As for the account problems, that was probably caused by the database crash not long ago that affected the main project too.

Sadly the issue persists. I'm going for bare bones here, no optimizations, but, I shouldn't need any compiler flags right?

No, probably not. The compiler flags I was using were OS X specific.
CFLAGS="-isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch i386 -mmacosx-version-min=10.4" \
CXXFLAGS="-isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch i386 -mmacosx-version-min=10.4" \
OBJCFLAGS="-isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch i386 -mmacosx-version-min=10.4" \
LDFLAGS="-Wl,-syslibroot,/Developer/SDKs/MacOSX10.4u.sdk -mmacosx-version-min=10.4"

Has anyone tried running BOINC w/ the MW ATI app in a WinXP VirtualBox under Debian/Ubuntu?

signed, Sharon LOL


How about WinXP 32b in VirtualBox under any 64b Linux?

Wouldn't work in VirtualBox, because it emulates a graphics card. The application/drivers need native access to the card to work.

So how exactly i put my GF cards to work this on Vista X64?

Right now, you can't. Once the CUDA application is finished, you can attach to whatever project hosts it (we still don't know if it'll be Milkyway or Milkyway_gpu), and BOINC 6.4.x or later should pick up the GPU app automatically.

Is this an issue stemming from an error in building boinc? Incompatible version of boinc (I got the 6.3.14 release via svn)? Any other insights? Thanks much in advance!

Yeah, looks like you'll have to recompile the BOINC libraries from source. Did the libboinc_api.a file come with the svn checkout, or did you get that from a configure run yourself?


I'm pretty sure libboinc_api.a was built by me. There was no lib or api directories prior to running the configure script and running make.

I've tried a few different versions in the 5.xx and 6.xx realms with no success. The method I'm using is from source...

./_autosetup
./configure --with-boinc-platform=powerpc64-ps3-linux-gnu
make
sudo make install

Is this wrong in any way?

I've never used --with-boinc-platform for my configure. For BOINC, I use
./configure --disable-server --disable-client --disable-manager
along with some custom compiler flags, as I usually build on an OS X system.

What catalyst version have you found to be most stable and not repeatedly BSOD or do anything else funky on a regular basis?

8.12 with a 4870 on Win7 RC x86_64.

Coiuld it be from not very powerful power supply? Ot htis would manifest itself in other way than BSoD ?

If you power supply was underpowered and you overdrew the wattage rating, your computer would probably just shut itself off. Have you tried searching around the web for the error code?

Post:
Hi, how important is the amount of RAM on these cards?
For example 4870 based cards are sold in 512meg and 1024meg versions.
Does this affect the RAC generated the card?

Mike.

No. The amount of RAM just affects the number of WUs you can run at once on the card, and usually 2-3 WUs at a time is enough to maximize the potential of the cards. 512MB should handle 2-3 WUs fine.

Disclaimer: I'm not sure how that will interact with the app_info file that drives the ATI GPU.

I'm running with ncpus = 5, avg_ncpus for MW GPU as 0.5, and a bit of custom resource shares (50 for MW and 100 for WCG). BOINC (well, Synecdoche now) always seemed to run 4 CPUs and 2 GPUs as long as one or other other didn't get hung and get debts up in the air.

EDIT: Oh, BOINC v6.2.19 and Synecdoche v0.1.1, Windows 7 RC1 64-bit.

ATI needs some of my money and I can't give it to them w/o a Linux version so I can buy another card or two.

Is there going to be a Linux version of this bad boy?

Talk to Cluster Physik. I believe he's said he won't release a Linux version of the current app (it's not even GPL'd like the rest of the source), but when the CUDA app source is release, he'll tweak that and release it as GPL (as he has to), and that's when we should get a Linux app. That's all I'm waiting for to shift my desktop over to Linux here from Win7.

not quite as limited as ATI applications (as in this is the only forward thinking game in town)

No kidding. AI was supposed to be working on an ATI app, but they just shut down a little while ago, so that's not coming. DA has said there probably won't be any ATI support in BOINC until around 6.10 or so too, so that's a bummer.

Pretty much nobody has the money for it.

Jedirock took a shot at it, but only managed about a 2% improvement since he used the same tools as Travis.

http://www.arkayn.us/milkyway/milkyway_0.18_mac.zip

Unfortunately, even on OS X, GCC is not compiled for Intel specific processors, so it runs slower than the Intel compiler, which generates slower code for other processors and faster for Intel processors.

Post:
which driver to use on win 7x64 for GPU HD4850 ?

You have a choice of Catalyst 8.1 or 9.1, or for 9.2 ad above see this post.

Generally it's always best to use the higher version numbers, but I've never had any luck with the drivers above 8.1, so I use 8.1 since it works for me.

Nice to see another Ukrainian on this forum ;)

You mean 8.12? I didn't think crunching was supported on 8.11 or earlier.

Post:
If nothing else split it into two:
web server,
the rest.
This will at least ensure that we get timely messages to say why we aren't getting any WUs. :)

Wouldn't help everything, because the website still uses the database used by BOINC. What would probably be better is to split the DB server off.

I've tested it on OSX and it works fine -- unfortunately AFAIK there is no 64 bit or PPC version of CUDA for OSX so it will only compile an i686 binary.

AFAIK, there is no CUDA library for OS X, period. Nvidia doesn't release separate drivers, so they have to work with Apple to get them into an OS update. With Apple pushing OpenCL though, they may have to go with OpenCL first. I don't know what Apple's schedule is on that.

unless the anonymous platform is banned!

Which would also disable the third-party CPU applications, which I don't think is practical.
