xpmclient 10.2.1 is out http://coinsforall.io/distr/xpmclient-10.2.1-beta.tar.gz
Difference from 10.2 is only target switch point, 10.994 now and it will not be changed.


thanks for the info.
what is the reason that you forcing target=11 before difficulty reach 11.00?

Difficulty also contains fractional part, it's a shares/blocks ratio. For example, with difficulty 10.0 all 10ch shares are blocks, with 10.5 - only 50% 10ch shares are blocks, with 10.994 - 0.6% 10ch shares are blocks.
When you switch miner target to 11, it generates 60% less 10ch shares, but 10-20% more 11ch shares (depend on type of GPU). So, miner with target="11" will generate more blocks, than miner with target="10" at diffuculty >= 10.99x.

really appreciate for that info and thanks for your great effort.
in a next couple of days we will reach 10.994 and miners should switch to target=11. what if they stay at target=10? your pools will accept those shares or reject those shares?
i am asking that because most of the network hashrate is generated by tonga, tahiti, hawaii cards and those cards performs very well because you made great 9.4.1 client with superb kernel for those cards. any newly compiled kernel give as 20-35% less hashrate. can you make new superb kernel with target=11 for those cards?
thanks in advance.

Hi, eXtermal, where can I find the source code for version 10.X? I want to compile it my own. The provided pre-compiled binary version hangs my PC which when I quit the miner (for playing my game). The github version dates back to 2014 and no source code for the new version. the old version no longer builts on modern ubuntu.

New version 9.4 with next speedup: https://www.dropbox.com/s/ny027u62vbeb2u5/xpmclient_v9.4.tar.gz?dl=0

let's make some benchmarks.
It's known information, you can't get good CPD with 15.12, need OCL from 14.x. This substitution works well on Windows 7 and Linux, but may not properly works on Windows 10.

Here is collection of OCL part from different drivers:

i have good CPD with 15.12 and stock kernel (target=10).
it is more or less same CPD compared to win7 with 14.6 driver.

none version xpmclient won't start with ocl 14.x
i can give you access to my computer via teamviewer so you can test anything.

Update:
Finally I got it to work!
It should be equal to 10.5-11cpd with target=10
Code:
[GPU 0] T=43C A=98% E=0 primes=0.104222 fermat=280227/sec cpd=0.38/day

[GPU 3] T=54C A=100% E=0 primes=0.104312 fermat=281100/sec cpd=0.39/day
[GPU 4] T=59C A=100% E=0 primes=0.104093 fermat=280431/sec cpd=0.38/day
[GPU 5] T=48C A=100% E=0 primes=0.104254 fermat=280590/sec cpd=0.38/day
(ST/INV/DUP): 1316x 7ch(1/43/7) 128x 8ch(1/7/0) 12x 9ch(0/0/0) 2x 10ch(0/0/0) 1x 11ch(0/0/0)
