So I finally did a 10k share test of the new code. 10349 shares, 13 rejects, so 0.12% reject rate down from around 0.48%, testing on BTCGuild.

So yeah, I think I can say my new code does what it was supposed to.

Sounds like you tried to download it from git and didn't run mvn package first. Use the binary zip if you don't intend on building it.

I have a 6990 and Debian unstable, which includes fglrx 11.9.1. I have tried AMD SDK 2.4 and 2.5. Either way, DiabloMiner uses about 90% of a CPU core when mining on one GPU, and about 180% (nearly 2 CPU cores) when mining on 2 GPUs.  It also causes lag when trying to play games on the primary GPU while mining on the second, which worked fine on fglrx 11.4.  I understand this is a driver bug, but how can I fix it?  Which driver can I install and how?  There's no fglrx driver at all in Debian testing (presumably due to bugs in 11.9).  Debian stable has no support for AMDOverdriveCtrl so I couldn't underclock my RAM.  I tried to downgrade my deb packages, but then got dependency problems with libmesa and couldn't install anything new.

Would AMD's installer for an intermediate version, like 11.7 work better?  Or can we just fix or report the actual bug in the driver?

Never try to use AMD's installer on a distro that provides packages. It usually just causes a mess.

Your only choice is to wait for AMD to fix it, but I suggest you keep trying to report the bug.

Games are probably lagging due to the CPU use bug, just turn DiabloMiner off when gaming.

is it possible to make this mine at about 3/4 of full speed on windows?  it seems like the -f doesnt do anything when i set it to more than a few hundred.

No. If you need GPU performance, just shut the miner off when you need it.

Update: Moved execution threads back down to 2 now that AMD has fixed the CPU usage issue, and merged patch to make DM work better on chains that have difficulty below 1

Updated: Added a whitelist to only BFI_INT patch on GPUs we know it works, should fix 79xx GCN until a better solution is discovered.

Some of the 7xxx family apparently are going to be VLIW4, but I don't know the code names for these for sure yet, I'll have to add those later.

Did some performance testing:

Catalyst 11.12 on Radeon 5850 at 960/320
-v 2 -w 256 -f 1
SDK 2.1: 400
SDK 2.4: 387
SDK 2.5: 387
SDK 2.6: 358

-v 2 -w 256 -f 1 -a
SDK 2.1: 400
SDK 2.4: 387
SDK 2.5: 387
SDK 2.6: 357

So. SDK 2.6 performance is pretty low and also phatk-like arrays no longer work against the driver with the most optimum settings. Lets try everything else.

-w 256
-v 1: 306
-v 2: 357
-v 3: 325
-v 4: 341
-v 5: 225
-v 6: 212
-v 18: 318
-v 19: 301
-v 20: 211
-v 21: 210
-v 36: 238
-v 40: 214

-w 64
-v 1: 306
-v 2: 349
-v 3: 340
-v 4: 348
-v 5: 303
-v 6: 257
-v 18: 313
-v 19: 305
-v 20: 297
-v 21: 297
-v 36: 365
-v 40: 214

-w 128
-v 2: 355
-v 4: 344
-v 36: 326

-w 192
-v 2: 351
-v 4: 297
-v 36: 323

With or without -a, the best seems to be -w 64 -v 36 for SDK 2.6. Weird. Still a fair bit slower than 2.1 and 2.4/2.5 though.

DiabloD3, what are those settings -w 64 -v 36 compared to cgminer options? I tried -v 4 -w 64.. much slower.

What hardware, driver, and SDK? I tested this on 11.12 and SDK 2.6, normal options apply to everyone else.

Much slower than -v 2 -w 256 on that same combination?

-v 4 -w 64 is about 50mh slower each GPU, the same with -v 2 -w 256. I just wanted to know the settings with cgminer compared to your miner using -v 36. What is -v 36 anyway?

P.S. the best result is with -v 2 -w 128 so far
