Boinc 6.6.38

I've got a 512 MB 4850, running 1 unit at a time, catalyst 9.9, Windows 7 x64, app 20b, seems to be running fine, no lockups that I've seen.
Is this card capable of running 2 WU's at a time without incident?

Question in general about the MW & Collatz apps. Since v2 Collatz has been more or less stable on my machines (both HD 4770 / WinXP32 / v9.8 no CCC / BOINC v6.10.13). MW runs fine when the machines are left as dedicated crunchers, but if I try to do anything else when MW is running (like open Windows explorer or running notepad, sometimes even bringing BOINC manager into focus) I'll get an immediate video crash. Given buggy ATI drivers, what could be the difference that allows Collatz to run with other apps and causes MW to crash? Possibly that MW is using double precision?

I have really no idea. Both applications access the GPU in exactly the same way. The only difference is what gets calculated. And I don't have those problems when using Catalyst 8.12. ATI apparently changed something in the drivers, what has broken them for MW on XP. Vista and Win7 drivers appear not to be affected and strangely it doesn't happen with Collatz either. I have a WinXP machine running Collatz with Catalyst 9.9 (and a 790GX chipset IGP needing just 11,000 seconds on average ;) without any problems.

Guess you have Crossfire disabled. With the newer drivers it's generally okay to run it with activated crossfire so both GPUs can be used.

I believe the saying in the USofA is it doesn't matter the amount, but that you did donate. I'm sure it's all appreciated, right people?

Hello again,

The server should be running nicer now (let me know if it isn't), we went from having 4 runs [2.5deg 2s (2): 2.5deg 3s (2)] to 8 [2.5deg 3s (4): 5deg 2s (2): 5deg 3s (2)]. So there are WUs in total, more 3 stream runs, and more 5 degree stripes.

On a thread-related note-- yes, we do go out of the way to make you guys happy with the server speed. But I think this is part of our relationship-- we keep you happy by giving you work and credits, you keep us happy by providing the computing power we need. If keeping your boxes busy is the price to keep you crunching for us; well, that's a small price for 430 TFlops :)

Cheers,
John Vickers

Well folks. Before you can run the script to make the project, you have to build the boinc system. Which, to say the least, is not pleasant on FreeBSD systems. Anywho, to update on the status, Travis is working on the GPU app. He has been working on it for the past 2 weeks. He has to translate the entire code from C into CUDA, which obviously isn't trivial. He told me the other day that he's got some functionality out of it but it's not yet complete.

That would mean only the 4890 cards are affected :(

Surprise, surprise.
Cuda capabale cards are listed here.
