[ANN][BLC] Blakecoin Blake-256 for GPU/FPGA With Merged Mined Pools Stable Net

[smolen]

error: Couldn't find kernel file -reaper.cl

Looks like reaper.conf is missing or there is no "mine blakecoin" line in it.

[fenix79]

cat reaper.conf | grep  "mine blakecoin"
mine blakecoin

[smolen]

cat reaper.conf | grep  "mine blakecoin"
mine blakecoin

Hmm, strange. Just in case, is reaper in the same directory as reaper.conf and is that directory current?
EDIT:
Try to unpack archive again in fresh empty dir, rebuild and run w/o changing .conf files. It will fail to connect to the wallet, but may be gives more meaningful error message
cmake .
make
reaper

[fenix79]

yes its but i am not have file reaper.cl

Any recommended settings for 7950 and 7970 cards?

GPU usage at 99% but temps are lower than scrypt/scrypt-jane/Sha256, though my settings are just start values...
Measured with MSI Afterbruner.

Got 4 blocks from 24000 shares, one in 6000 for me, far from 1/2000.

What aggression are you at?

I am at aggression level: Very angry.
The reaper was set at agression 26, think I ran the default agg value.

Anyways, my new favorite settings for the XFX 79xx cards (that some claim are bad for mining)

worksize 256
aggression 25
threads_per_gpu 2
cpu_mining_threads 0
vectors 1
gpu_thread_concurrency 8192
sharethreads 32

At 1000Mhz it gives me 2.34Mh/s with instant 99% GPU usage, unlike other settings that slowly ramp up.
Still sucks at delivering blocks though.

/EDIT: Lowered aggression to 25 for a 2% CPU usage, that hopefully does not lock the wallet...

[3dcgminer]

From normal reaper info:

Set thread_concurrency to 64 * bus_width_of_card_in_bits.  So, for a 7950, that would be 64 * 384 = 24576.
but is also saw for 7770 use 8000

My 7770 stabilized at 792MH/s with just less than 10,000 shares have found 7 blocks on took less than 5 min there is a LOT of variance this early in the game.

 

Wow, I really hate you now, I got 4 blocks at 30 000 shares, running at 7GH/s and still getting next to nothing.

[smolen]

At 1000Mhz it gives me 2.34Mh/s with instant 99% usage, unlike other settings that slowly ramp up.

To lower CPU usage run with "START /BELOWNORMAL reaper.exe" (Windows) or "nice ./reaper" (Linux)

Thanks, I meant GPU usage from Afterburner.
But you are correct, it seems like the reaper eats up 38% of my CPU, which may affect the wallet as mentioned previously, thanks, will try the priority thing.

Guess I'm just lucky found another one an hour ago 11,500 shares 8 blocks 99.93% Stale



one only took 3 min

ok work

On 7xxx series cards I would try this: (see the posts from others with same card for best results)

worksize 128
aggression 27
threads_per_gpu 1
cpu_mining_threads 0
vectors 1
sharethreads 8
gpu_thread_concurrency 24000

This works well on 6xxx series cards:

worksize 128
aggression 27
threads_per_gpu 1
cpu_mining_threads 0
vectors 1
sharethreads 8
gpu_thread_concurrency 12288

This works well on 5xxx series cards:

worksize 128
aggression 27
threads_per_gpu 1
cpu_mining_threads 0
vectors 1
sharethreads 8
gpu_thread_concurrency 8000

all the above can up the aggression if it is a mining rig but the wallet connections can drop if the miner is using too much cpu time so if the rig does not have a wallet running try 28-29

I have only tested
5870
6970
6950
6870
6850

I do have a Nvidia GTX 460 in my bits box will dig it out and test that once I have some spare time

On the 5870 I'm running, work size of either 64 or 128 work the same. What's the correct RPC port? The OP says 8227. The miner has 8984.

Thanks for the awesome work Vorksholk


However some are tempted to overclock their gpu, i think psuhing up the memory does not make any difference
If the coin is a true sha256 you could in fact do with memory as low as 300 Mhz.
I must warn though about this memory speeds because several newer models do not like changing the speed lower then the core speed, in my case the 7970 sapphire dual x does run fine at 1000 Mhz core and 300 Mhz on memory

I have been playing alot with the parameters of reaper but i do not see any significant change in performance in any setting the most plain setting seems to give the best result.
But its hard to tell since we are not able to see the hash speed at the program
And the numbers go all over the place with different settings, mostly ending up showing around 80000 Kh on my card
It says 2.05 Gh at the first number but i wonder if thats a real performance of this card with only 22 aggr.
I will post the shares processed after each 1000 seconds

it is whatever you set it in the blakecoin.conf in your data directory, in the protocol.h the ports are set as testnet 18773 : main 8773 but this value is overridden by the rpcport=8772 in the wallet conf file hope that explains any differences you see  

just make sure they match what you are using in the miner conf

Any RPC port will work, although it has to be the same one for the miner and for blakecoin (set in AppData/Blakecoin/blakecoin.conf if on Windows...)

Thanks I didn't make the miner however, I just paid smolen to cover the time it would take him to do it.

On my 7970s 28 aggression seems to work best, though mine are XFX GHz edition. They are at a slight overclock.

[bronan]

Well thanx to smolen for taken the job as well then

Well i did not oc mine but this one is a Gh edition as well however for power usage
I had another one but that died a few weeks ago, i was impatient and could not find the bill so i threw it away, i alos sold a few gpu's since they all where no longer paying off in mining.

At present i am tempted to switch it back to 900 Mhz mode because i pay 0.23 Euro Kw/h in us dollars thats 0.32 per Kw/h

At 1000 Mhz i get ofcourse faster shares processing but as anyone can understand the cost of letting this power draining monster run constant will make a huge dent in my wallet when the bill arrives next year in july ....

Our system works different from most countries i know, we pay upfront a set amount each month which is based and previous years usage.  So in my case i pay 345 euro a month upfront this is kinda high but then again i used to have a butload of graphics cards running in the paste. So 342 x 12 months makes 4104 euro.

Last year i had to pay 1600 euro extra on top of the 4104 euro because of 7 months gpu mining with 4 machines.
Ofcourse this amount is not only electra but includes also gas for the heating and cooking and ofcourse the biggest amount is for all the taxes added by government.

So far the progress on mining goes, I got 2 block in the hours it has ran since you released this reaper
And that made me think would it be possible to run the 64 bit reaper as well  ?
I sure would like to test if it does have any effect on the mining speed, with scrypt mining it did.
Not sure it will do anything for blake ..

I still think some people are running asics on blake, they should know its useless.

lower your memory clock while mining blakes!

Ok, I'll use 8227 as stated in the OP. I'm assuming that the stale are because of the getwork network, right?

Oh, as a note: tons of stales is fine. If the network difficulty is 2,000, you can expect, on average, to need 2,000 difficulty-one shares. The miner submits every difficulty one share, and when it is rejected it counts it as a stale. If you see your stales around 3x the difficulty with no accepted blocks, then you might have a problem. Just let the miner run. 

I'm running 99.93% stale the .07% are found blocks. ~15,0000 shares completed
