Message 47162 - Posted: 8 Apr 2011, 1:08:23 UTC

Just curious if the XFX HD 6870 will run Milkyway... currently running 1 HD 5870 that seems to take about 1 1/2 mins per WU...
Thanks

No - you need to go to 69XX. Milkyway needs double precision support, 6870s do not support Double Precision

Just connected this PC to MW@H.
No error message re GPU.
But the HD4350 (RV710) is getting no work.
Is anyone else with this GPU working MW@H?
(FWIW it works fine with Collatz).

See the top post in the thread and then add the HD5830, HD6950 and HD6970 as DP capable ATI cards also.

Am I correct, since the server and client change, the ATI Radeon HD38x0 cards (I have an HD3850) can no longer crunch Milkyway.

If this is correct, then Anthony's list of DP compatible cards should be amended.

If this is not true, then what needs to be done to make it so, and crunch as before.

My PC is an XP 32bit, HD3850 on BOINC Manager 6.10.58 (was recently 6.12.22 and can be easily made so again). The driver is 9.3 (1.4.558) and I keep getting BSODs when trying to move to 11.3 (with APP).

@ JohnC:

I am running the new app on a 3850 with this host (WinXP32 SP3, BOINC 6.12.22). I don't know how it differs from the driver you tried, but I loaded the 11.3 AGP Hotfix.

Thanks for the positive reply Mark

Most of yesterday afternoon and evening I was fighting BSOD on my dual 32bit Prestonia Xeon server running under XP pro 32bit.

My order of business was shutting down BM (6.10.58), uninstalling it from Control Panel then reinstalling BM 6.12.22 and relaunching. Things went OK.

I then uninstalled the ATI driver 1.4.556 at Control Panel (it was not complete, rebooted and the desktop comes up. After the Firewall/AV checked for the latest AV database download, but before BM connected to Boinc.exe it Blue Screened. The cause is always the top 2 HID components in Device Manager - The HID Non-User input Data Filter (KB 911895 signed twice).

I have not been able to strip all ATI drivers away using Driver Sweeper (in Safe Mode) as it will not launch (it is installed).

Is there any order of Driver and AGP hot fix uninstall and install order you used to get things going. For example - should I load the AGP Hot fix first, then uninstall drivers before 11.3.

I presume you installed 11.3 with the APP in the CCC?

Glad to help however I can, John. :-)

Unfortunately, my GPU/driver troubleshooting experience is limited and I'm not sure in what order things need to be or should be done -- my currently working solution may be the result of luck. In my haste to get crunching again, I just downloaded and installed the Hotfix for WinXP Pro/Home over the existing driver I was using (10.10). I did not install or uninstall any other components or drivers. (It was only later that I saw the reference to Article GPU-2. I did not follow those instructions and don't know what the failure to do so is or might be.)

I presume you installed 11.3 with the APP in the CCC?

Sorry, but I don't know if the APP is included in the Hotfix. I also don't know if APP was included in the 10.10 driver when I installed it or if that makes any difference.

HTH,

Just a quick observation on GPU's. I've just got an HD4770 up and running and the stock settings are :-

GPU 750 MHz
Memory 800 MHz

I just re-clocked it with fan speed 50%, temps 65C, activity 98% on MW

GPU 830Mhz
Memory 400 Mhz

My HD4850 card on MW = 321 secs for 267 credit
My HD4770 card on MW = 304 Secs for 267 credit

These HD 4770's rock!

Don't drink water, that's the stuff that rusts pipes

I think part of my problem with the dual 32 bit Xeon, under XP, is to do with the recent big MS security patch update.

I have rolled back to March 8th, and all is stable and crunching ATM. Unfortunately, this means there is even more security patches needed to replace the ones lost in the roll back. I will allow one security patch at a time to install, which between now and sometime, I will need to reboot this rig many many times to ensure things are running smoothly.

In the mean time I can check the ATI.AMD 11.3 APP drivers have the AGP hot fix and do your approach (install over the 9.3 driver that currently exists and see if all is OK.

Any comments Zydor?

Cant see the security updates stopping any graphics card driver installs.

Clear risk when installing over the top of a previous driver. So if it falls over, best to clean out using Driver Sweeper, then reinstall.

Agreed, but MS has made a distinction between server and workstation versions over the last few years. Perhaps that could explain it.

NVIDIA GPU 0: GeForce GT 430 (driver version unknown, CUDA version 4000, compute capability 2.1, 1024MB, 179 GFLOPS peak)

This card seems to be sufficient for the currently offered tasks.

All of them were finished in 10 - 50 minutes ...

Even if on the back-end you guys are refactoring your programs to use OpenCL for better cross-hardware and cross-platform support, wouldn't it be worth it to update the old code to accept newer cards as a stop-gap solution?).


It would actually be less work to just finish the OpenCL. I haven't been able to get the existing CUDA to build since I started working on the project. I actually expect to have the OpenCL actually working later today, and ready to send out within a week or 2.


How does the OpenCL version access the GPUs? Does BOINC 6.10.58 have enough OpenCL interface support? Does it require the 6.12.* beta test versions of BOINC or do those have enough OpenCL interface support either? Or does it bypass the BOINC method of accessing the GPUs and include the OpenCL method as part of the application program? Or have you found some software for turning compiled OpenCL code into the CUDA code that versions of BOINC can already handle?

Also, how do you check whether various Nvidia cards have any double precision capability or not? Nvidia appears to list that information for Tesla cards, but not for the cheaper Fermi-based GTX 400 and GTX500 series cards, even though I've read that some of the GTX 400 and GTX 500 series cards are based on the SAME GPU chip as the Tesla cards, so I'd expect them to have at least some double precision capability.

I currently have a GTS 450 card, so answers for the Nvidia cards would be the most useful now. However, I've decided to get into BOINC-relevant programming, so answers for the ATI cards would be useful eventually as well. NOT ready to actually do much yet, though.

It uses whatever device ID BOINC passes which is the same as it was for CUDA. This works so long as you don't have other OpenCL platforms installed (i.e. Both AMD and Nvidia OpenCLs installed). I also think this only happens to work since Nvidia's implementation doesn't support the CPU. There was some discussion on the BOINC lists about different CL devices and platforms should be enumerated but I don't think anything has come of it yet.

All of the Fermi based GPUs support doubles.

Old and very slow by current standards. Here's some info:

http://www.gpureview.com/radeon-x600-pro-card-94.html

http://www.gpureview.com/radeon-x700-pci-e-card-98.html

Not sure if they do DP at all but if they do they would be very slow.
