Hi,
i'm trying to use windows binaries, but i got this :

So, only one card out of 5 can mine.

i run this command line : boolbd --start-mining=1JNsCgTA1pK7ksYpZPsDDV7HihrAN5JKMTNA17fwk6aQD2CknCd34A5UKaZBxft8B9Z6mKFxKuWkheccMdbda2iARS88Y6r --mining-threads=5

In the .json file, i got this :

{
  "current_extra_message_index": 0,
  "device_index": 0,
  "difficulty": 16777215,
  "donation_decision": true,
  "donation_decision_made": false,
  "donation_descision": true,
  "donation_percent_opencl": "2.0",

  "kernel_type": 0,
  "platform_index": 0,
  "thread_delay": 100,
  "work_size": 262144
}

The download link for windows binary doesn't work?

Read the main thread for BBR, there is a new update miner to download.

What did i do wrong?

--mining-threads=1

No matter how many cards you run, it's in the read me from the source.

"thank you for your "answer", but in the readme file, i read :
"--mining-threads=[n], n - number of GPUs to use"

[drkman]

Are these the proper instructions on how to mine on Windows?  Is there another method?
"Windows

Dependencies: MSVC 2012, CMake 2.8.6 or later, and Boost 1.55.

You may download them from:
http://www.microsoft.com/en-US/download/details.aspx?id=34673
http://www.cmake.org/files/v3.0/cmake-3.0.0-win32-x86.exe
http://sourceforge.net/projects/boost/files/boost-binaries/1.55.0-build2/boost_1_55_0-msvc-11.0-64.exe/download

OpenCL SDK (you can install CUDA too):
http://developer.amd.com/tools-and-sdks/opencl-zone/opencl-tools-sdks/amd-accelerated-parallel-processing-app-sdk/

To build, edit paths to Boost in cmake-vs2012.bat and run it.
Open the generated build/boolberry.sln in VS2012, change the solution configuration to Release and build the targets you need in the prog group.
You'll find executables in build/src/Release directory.
Copy *.cl kernels from src/cl to executable's directory.

Good luck!"

.....

No, those instructions are to build the windows programs, something most people (including me) can't do. MBK had the files ready for download, but the link no longer works. If he is unable to put them back up, I will get zoidberg to try to build them.

[btc-mike]

I added a brief summary to the first post of this thread. Let me know what else to add. Probably needs more Linux build info.

Merged all updates from the main branch.
Source - https://github.com/mbkuperman/boolberry-opencl
Windows x64 binaries  - https://github.com/mbkuperman/boolberry-opencl/releases

Fixed previous binary release too (it was compressed with 7zip instead of zip).

In the logs you posted before I see

Code:

-- OpenCL: Searching in custom location

It means CUDA_PATH variable is not visible to cmake. Is it still the case? Delete the build directory or better clone the repository from scratch and run make again.

When building on Linux you should:
1. Run 'make clean' if you got back here after some problems.
1. Set CUDA_PATH or AMDAPPSDKROOT, run 'printenv' to check.
2. Run 'make' and watch for OpenCL: Searching for NVIDIA CUDA SDK or OpenCL: Searching for AMD APP SDK. Back to 1st step if it's not in the log.
3. Watch for -- Looking for CL_VERSION_1_x - found. Check the environment variable points to the actual SDK directory if it's not in the log and get back to 1st step.
4. Check the other dependencies were found (Boost).
5. Compilation should start.

first steps clear. CUDA_PATH set. printenv checked.
3. is the problem. -- Looking for CL_VERSION_1_1 - found - is ok - but afterwards the compiler shows my beloved message:
CMake Error at /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:108 (message):
  Could NOT find OpenCL (missing: OPENCL_LIBRARY) (found version "1.1")

with the boolberry miner version from the 22. July (you fixed backward compatibility after for openCL 1.1/1.0) he shows the right path afterwards:
-- Found OpenCL: /usr/local/cuda/include (found version "1.1")
...and failed later (https://bitcointalk.org/index.php?topic=577267.msg7972653#msg7972653)
but with the actual version I did not get so far.

compiling cudaminer and ccminer forks were no problem so far.

[mbk]

Yes, you can use as many GPUs as you like with solo miner (single thread in readme is about pool miner). Try larger values for thread_delay if config file (ex. 2000). It's in milliseconds.

No. It was the case before as you advised to set OPENCL_ROOT (a few days ago).
But the defined path doesn't make a difference... the error is the same.

With set CUDA_PATH he is searching for the nvidia cuda SDK - and he found the CL Versions as you could read in my logs...
the problem is described in this post above, please take a closer look:

Looks like the OPENCL_LIBRARY is undefined. It should be in line 149. Edit FindOpenCL.cmake. Put debug messages after the find_library call.

Code:

  # Find the library
  find_library(OPENCL_LIBRARY OpenCL
    PATHS /lib${_OPENCL_LIB_DIR_SUFFIX}
    ${_OPENCL_LIB_OPTS}
    ${_OPENCL_ROOT_OPTS}
  )

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

wow! get it on... you do a lot of cool stuff at the moment (tsiv CN).
If your BBR version would be easy to compile for nvidia linux guys I would be more than happy.

[PVmining]

Looks like the OPENCL_LIBRARY is undefined. It should be in line 149. Edit FindOpenCL.cmake. Put debug messages after the find_library

thanks... I hope that brings us a step further.
I will try this tomorrow when I'm back at home.
Have a good time.

Hi,can u help meu with a config of your bat file

Thx in advance

Hi,

I am having similar problems to Antonio with the miner. My environment is following:
-Ubuntu 14.04
-Biostar HB61 + 5 x 7950
- AMD drivers 14.6 beta
- AMD APP SDK installed version 2.9
- miner compiled with make -j=5

once I start mining in simple wallet using start_mining 5 I am getting following:

If necessary I can also downgrade to Ubuntu 13.10 with AMD 13.12 drivers. (althought it would take me several hours)

I gave the suggestion on both threads before but here it is again:
Try larger values for thread_delay in config file (ex. 2000). It's in milliseconds.

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

2014-Jul-27 01:55:55.783175 ERROR /home/klemen/boolberry-opencl/contrib/epee/include/net/abstract_tcp_server2.inl:475[bool epee::net_utils::boosted_tcp_server<t_protocol_handler>::init_server(uint32_t, std::string) [with t_protocol_handler = epee::levin::async_protocol_handler<nodetool::p2p_connection_context_t<currency::currency_connection_context> >; uint32_t = unsigned int; std::string = std::basic_string<char>]]Exception at [boosted_tcp_server<t_protocol_handler>::init_server], what=bind: Address already in use

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

I gave the suggestion on both threads before but here it is again:
Try larger values for thread_delay in config file (ex. 2000). It's in milliseconds.

after reading this important info:

Copy *.cl kernels from src/cl to executable's directory.

I am getting following:

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

solved!It works now~
the thread_delay default should be set @2000

[crazycoin]

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.
