You should start rolling out pre-compiled compressed files or something. It's getting above my knowledge, lol!

DiaKGCN kernel is ready, if you like try it with VLIW5 and VLIW4 hardware It should be interesting how worse or good a GCN optimized kernel performs on older hardware:

Tried out diakgcn on my 6870. All tests at aggression 12 and done over very short time periods, unless said otherwise.

Results:

2.5:
phatk_dia, WORKSIZE=128, VECTORS: 282 MHps (best one from previous test)
diakgcn, WORKSIZE=128, VECTORS: 278 MHps
diakgcn, WORKSIZE=128, VECTORS2: 279 MHps
diakgcn, WORKSIZE=64, VECTORS: 278 MHps
diakgcn, WORKSIZE=64, VECTORS2: 279 MHps
diakgcn, WORKSIZE=128, VECTORS2, AGGRESSION=10: 278 MHps (spiked up to 282 at one point.....)
diakgcn, WORKSIZE=128, VECTORS2, AGGRESSION=5: 275 MHps

2.6: (Sorry, did poor documentation here. Only listed best results If asked for I will document this better later)
phatk_dia: 272 MHps
diakgcn: 260MHps

tl;dr: diakgcn is currently slower for 6870

Thanks for your results, that behaviour was awaited ... now it's confirmed. Well DiaKGCN is not finished, so perhaps it will get better for older cards over time Smiley.

Since you had an update today, I guess I'll retest. (diaggcn?Huh, spelling mistake?). Like before all test are short test at aggression 12, unless stated otherwise.

2.5
phatk_dia, WORKSIZE=128, VECTORS: 282 MHps
diaggcn, WORKSIZE=64, VECTORS: 248 MHps
diaggcn, WORKSIZE=64, VECTORS2: 277 MHps
diaggcn, WORKSIZE=64, VECTORS4: 545 MHps  (Guess the vectors 4 bug has not been fixed? That probably means this is 272MHps)
diaggcn, WORKSIZE=128, VECTORS: 248 MHps
diaggcn, WORKSIZE=128, VECTORS2: 277 MHps
diaggcn, WORKSIZE=128, VECTORS4: 551 MHps (Probably 276MHps)
diaggcn, WORKSIZE=256, VECTORS: 248 MHps
diaggcn, WORKSIZE=256, VECTORS2: 271 MHps
diaggcn, WORKSIZE=256, VECTORS4: 540 MHps (Probably 270MHps)
diaggcn, WORKSIZE=128, VECTORS2, AGGRESSION=10: 276 MHps

might test my card on 2.6 later, but on 2.5, I am getting worse results than before, oh well.

DiaKGCN -> Diapolo Kernel Graphics Core Next

As I said, the new one this is for the 79XX cards, but I really would be interested in how it performs on older cards with current drivers / OpenCL runtime.
The next time you should perhaps reply in the other thread, as I won't work on phatk_dia anymore.

Thanks for your tests,
Dia

Now tried on 12.1 and SDK 2.6.

HD 6850 - 35 Mhash/s slower
5850s - 100Mhash/s slower

win7 64 pro
-k phatk AGGRESSION=12 VECTORS2 WORKSIZE=128

5850s are 80 Mhash/s slower if I turn the 6850 off
a solo 5850 will be only 5-8 Mhash/s slower if ran on its own
6850 3 Mhash/s slower when ran on its own

only solution was to run miner on all 4 cores, instead of 1 but then it is utilized in 50-75% (=more heat)
only then I get 5-8Mh/s less

any ideas?

Wouldn't it be easier to separate the kernels out for each of the 5xxx, 6xxx, and 7xxx series cards instead of trying to make a one size fits all. Is it possible to test at start up and exclude cards that a certain kernel isn't designed to run on? I hate to see you wasting time supporting the older cards with new kernels.

Easy answer, I just focused on GCN performance with DiaKGCN, that it runs on VLIW4/5 is just nice to have. I won't spent anymore time in optimising performance of phatk_dia or DiaKGCN for older cards. I even don't know for what I do all this, because this one (phatk_dia) seems to not be faster really for anyone + no one cares to support development via a small donation. People seem to just donate something if they gain 10+ MH/s over another kernel ... my hard work that was put into a specific version is not paid any attention to it seems :-/.

Can someone tell me which aggression setting gives me the absolute best performance with my HD6950 (Heavily OC'd with unlocked shaders) please as I can't seem to find it in this thread or anywhere? I also want a list of flags for this miner (running in GUIMiner with Phoneix as polcm kept having issues lately)

thanks

AGGRESSION=12, higher levels will lead to an idle miner in Phoenix, because it can't get work fast enough. Perhaps 13 or 14 works for your setup!

Available switches can be found in the init file:
Code:
PLATFORM = KernelOption(
'PLATFORM', int, default=None,
help='The ID of the OpenCL platform to use')
DEVICE = KernelOption(
'DEVICE', int, default=None,
help='The ID of the OpenCL device to use')
VECTORS2 = KernelOption(
'VECTORS2', bool, default=False, advanced=True,
help='Enable vector uint2 support in the kernel.')
VECTORS4 = KernelOption(
'VECTORS4', bool, default=False, advanced=True,
help='Enable vector uint4 support in the kernel.')
FASTLOOP = KernelOption(
'FASTLOOP', bool, default=False, advanced=True,
help='Run iterative mining thread.')
AGGRESSION = KernelOption(
'AGGRESSION', int, default=5, advanced=True,
help='Exponential factor indicating how much work to run per OpenCL execution')
WORKSIZE = KernelOption(
'WORKSIZE', int, default=None, advanced=True,
help='The local worksize to use when executing OpenCL kernels.')
BFI_INT = KernelOption(
'BFI_INT', bool, default=True, advanced=True,
help='Use the BFI_INT instruction for AMD GPUs.')

Remember, this one will get no further development time!
