Weird. I was testing there, too. Just kept looping "Job difficulty is 0. Skipping the job." Guess it IS just me. What could be different?

Right on....

Any plans on making this working with CryptoNote multiminer instead?

Added the release. It works on bbr.farm:1111 and makes about 80% of solo version.

Thanks. Can you post another windows release with this please? I don't have an environment ready to make a build and someone was asking me for it.
Edit: Actually this makes it so it never gets work it looks like.. unless it's just me

is there any miner for cuda compute 1.2?
cuda developper kit dont install on my pc

1. I didn't change the get_whole_scratchpad so if it has a bug (looks like it has) it's better to contact the main branch developer as well.
2. m_job.difficulty shouldn't be zero. If it is - something's wrong with a pool. I added a return from the worker thread as it doesn't make any sense to search for nonce having wrong data.
updated github

mbk, can you add m_scratchpad.clear(); at the beginning of the get_whole_scratchpad function. if the miner gets to a point where it wants to download the whole scratchpad again, it just appends instead of starts over.
Also, on my nvidia card it crashes because difficulty is zero at the start and it divides by that. I just put put a check for if zero, set to something else and it doesn't happen again.

Did a test on my 750Ti.

foxy! and I mean the numbers...  

It's simply a modification to mbk's OpenCL kernel. Nothing else needed.

Thanks for info. I found out Nvidia included libOpenCL.so in their driver not toolkit prior to cuda6. We need different cmake script to get them. I think it's OK to require cuda6 to make things simple. I'll add it to readme.

mbk, you would not belive it - I could compile your miner!
I located the problem with the help of your debug messages. thanks... this was really helpful.

1) It is not possible to compile your miner with cuda 5.5 (as used in kopiemtu).
There is no libOpenCL.so as you expect in usr/local/cuda/lib64/
So if you don't know a workaround for cuda 5.5, it would be helpfull to warn people in the readme.

2) After switching to cuda 6.0 it was easy to compile a working miner.
I tried cuda 6.0 before you made your code compatible for the "older" openCL versions - but not again after the fix. 

Finally I managed to make it run. Basically I have deleted files, make git clone and re-compile the miner. This time I have used command make instead of make -j 5.

Few advices for installing on AMD/Linux. Don't use getPimp or Bamt. They are based upon old Debian. The only way to get required dendencies is by mixing stable and testing packages and that creates less than ideal environment.

Better way is:
1. unplugg all but first gpu  (otherwise Ubuntu fails to install)
2. install Ubuntu using stock drivers
3. google "unofficial AMD community" and get instructions how to install latest AMD driver
4. shutdown computer and plug in all gpus
5. re-execute sudo aticongif --adapter=all --init -f and reboot
6. install AMD APP SDK
7. install AMD ADL (if required, e.g. for Sgminer)
8. follow instructions on boolberry.com
9. before make command, execute export AMDAPPSDKROOT=/opt/AMDAPP
10. create folder, e.g. mkdir dr1
11. execute deamon using folder dr1, by doing that deamon creates json file
12. exit deamon
13. edit json file and change thread delay, make it 4000
14. create wallet using simplewallet and execurte command address to get wallet address
15. start deamon using folder dr1, wallet address and specifying desired number of mining threaths

basically you may follow any web guide for installation of mining rig, but you must unplug all but first gpu before initial Ubuntu installation

if you are sattisfied with AMD 13.12 drivers, you may install stock UBUNTU 13.10 and follow this guide

https://github.com/joshpatten/mining-bootstrap

afterwards proceed with instructions on boolberry.com

I am getting 811500Hs on Sapphire 7950 at stock frequencies drawing 148W from the wall.

It works on Windows as is but try to change --rpc-bind-port and --p2p-bind-port command line options:
and so on. And don't forget to increment device_index starting from 0. Wait mining start before running next instance.

Got a 42.6% increase on my 860M, which is basically a 750Ti. That took a while.

Proof: https://ottrbutt.com/tmp/bbropenclstock2.png vs. https://ottrbutt.com/tmp/bbropenclwolf2.png

I have set thread_delay to 4000, but still does not work.

Is anybody else using latest beta 14.6 drivers?

Is there a way to manually start single instance with mining_threat=1 that would bind to 2nd or 3rd gpu? Perhapss using  "device_index" field? Because in thatt case I would manually start 5 instances of miner.

I am trying to execute following:

./boolbd  --start-mining=1F9hbj8w... --mining-threads=1
./boolbd --data-dir dr1 --start-mining=1F9hbj8wp... --mining-threads=1
./boolbd --data-dir dr2 --start-mining=1F9hbj8w... --mining-threads=1
./boolbd --data-dir dr3 --start-mining=1F9hbj8....  --mining-threads=1
./boolbd --data-dir dr4 --start-mining=1F9hb... --mining-threads=1

first instance works, but second do not, I am getting following error message

also setting   "thread_delay": 2000, and using 5 mining threads do not work

It seams that first gpu is working and other are not.
