Hi
Can anyone help? I can't edit my account on the ny2 pool. I get this message ending" | | | | | | unused1 | unused2 | Duplicate entry '' for key 'coin_address_mm4'". The identical page on the eu3 pool updates without a problem.
Thanks

just tested new cl
with 13.12 drivers no gain at all
with 14.7 driver - tons of HW with 280x card
with 13.12 drivers no gain at all
with 14.7 driver - tons of HW with 280x card
This is the version I am testing with no HW errors(14.4 driver win 7 x64) I see about 1%-2% gain with new optimized cl kernel
http://www.blakecoin.org/cgminer_3.7.2_pools.7z
btw, what version work on linux without hw? we tested some and they all produces hw...
I build from source on linux
Thanks to Calhil a build guide to cgminer on ubuntu is here https://bitcointalksearch.org/topic/m.6764336

Had an issue with NY2 pool worked with provider needed to move to a new ip address, ping ny2.blakecoin.com to double check you get the new server ip 107.170.132.68 as DNS can take some time to converge

I've completed some more performance work on blake256.cl and updated my gist https://gist.github.com/Griffitsj/55349ccee17bbf87ffd5
This gives 1.3% speed improvement on my rig. To use it you need to replace the blake256.cl file in your cgminer directory and delete all the .bin files. This only works with the 3.7.2 cgminer release for blakecoin by the way (windows + linux)
The optimisations are basically rewriting it to explicitly use vector based operations (uint4). Using the OpenCL profiler it confirmed that there were some performance improvements:
Interestingly the vector changes themselves didn't give the speedup I was hoping for as it seems the OpenCL compiler is clever enough to use vectors if it can but some of the other changes I made while restructuring to use vectors must have had a beneficial effect.

- clock cycles per wavefront went from 88 down to 84
- Scalar ALU operations went from 18 down to 17
- Scalar General Purpose Registers went from 22 down to 19
- All other metrics stayed the same

Sorry for my bad english.
I have tested blake whit nvidia, i download and use cudaminer. To the pool, i have read 1,4 ghs but to the windows of cudaminer i have read only under 700 mhs.
Later 1 hour of mining whit nvidia 750ti , i have earn 0,01 blake , 12 pho and very low other coin
so, 750ti do about 0.7Gh on blake? I have tested blake whit nvidia, i download and use cudaminer. To the pool, i have read 1,4 ghs but to the windows of cudaminer i have read only under 700 mhs.

New tab at 13 sat per GH/s a day. with no ELT was slight loss with it up again should now be slight profit

thanks. good work. but you show results if to sell directly. It was more interesting to look if the person wants to invest in coins and buys them.
if I have .0156BTC to spend now should I buy coins direct or buy mining?
You are right I am showing only what happens if you want to spend btc to rent let it mine then cash in coins and see if I have more or less btc when done.
What I can try is if I spend btc to rent let it mine see how many of each coin I got. then see how much it would cost to buy that same number of each coin. Since the Sell price is higher it would show you would have to spend more BTC to get same number of coins.
I think I would need to record sell price at start of mining and at end I try adding that to the next time I try renting again
add two positions - sell and buy coins at the end of the lease. range between the sell and buy at times 25-30%.

Did anything change for EU3 pool? My miners cannot connect, they go straight to NY2.
server changed so ip is different also the auto admin can throw a false positive and block some people from time to time pm or post your ip can check make sure its not on block list
