j"1LAnZuoQdcKCkpDBKQMCgziGMoPC4VQUckM!<div class="post">Hello All,<br/><br/>I tried without success to use the Python OpenCL Miner, here's what I did and what I got :<br/><br/>First my config, I run on Windows 7 Pro 32 bits with a NVIDIA GeForce 9800 GT.<br/><br/>I downloaded and installed CUDA Toolkit from :<br/><a href="http://developer.nvidia.com/object/cuda_3_2_toolkit_rc.html#Windows%20XP,%20Windows%20Vista%20and%20Windows7">http://developer.nvidia.com/object/cuda_3_2_toolkit_rc.html#Windows%20XP,%20Windows%20Vista%20and%20Windows7</a><br/>-> cudatoolkit_3.2.7_win_32.msi<br/><br/>I downloaded Boost 1.44.0 and built it with :<br/><div class="codeheader">Code:</div><div class="code">bjam.exe toolset=msvc --with-python --with-date_time --with-thread threading=multi link=shared</div>as did davidonpda on the post #81.<br/>Then I copied all the dll from H:\boost_1_44_0\stage\lib to system32.<br/><br/>I downloaded and built pyopencl-0.92 :<br/>1) running > python configure.py<br/>2) modifying siteconf.py :<br/>(example from <a href="http://www.mail-archive.com/pyopencl@tiker.net/msg00349.html">http://www.mail-archive.com/pyopencl@tiker.net/msg00349.html</a>)<br/><div class="codeheader">Code:</div><div class="code">BOOST_INC_DIR = [r'H:\boost_1_44_0']<br/>BOOST_LIB_DIR = [r'H:\boost_1_44_0\stage\lib']<br/>BOOST_COMPILER = 'msvc'<br/>BOOST_PYTHON_LIBNAME = ['boost_python-vc90-mt-1_44']<br/>USE_SHIPPED_BOOST = False<br/>CL_TRACE = False<br/>CL_ENABLE_GL = False<br/>CL_INC_DIR = [r'E:\NVIDIA GPU Computing Toolkit\CUDA3.2\include']<br/>CL_LIB_DIR =

|| true<br/>4) running > python setup.py build<br/> -> compilation without error<br/>5) running > python setup.py install<br/> -> installation without error<br/><br/>I downloaded poclbm from <a href="http://github.com/m0mchil/poclbm">http://github.com/m0mchil/poclbm</a><br/>-> m0mchil-poclbm-cf33815.zip<br/><br/>And trying to run it : > python poclbm.py<br/><div class="codeheader">Code:</div><div class="code">Traceback (most recent call last):<br/> File "poclbm.py", line 5, in <module><br/> import pyopencl as cl<br/> File

introuvable.</div>(the text in french with the fucked accents means : The specified procedure could not be found).<br/><br/>Note : I don't make all running together the first time, it took a long time and I can forget some step.<br/><br/>I also tried poclbm_py2exe.7z that I got from the board (post #87), first with the original OpenCL.dll in the archive, I got an error due to my Nvidia card I gess :<br/><div class="codeheader">Code:</div><div class="code">No device specified, you may use -d to specify one of the following<br/><br/>Traceback (most recent call last):<br/> File "poclbm.py", line

'uint2'<br/> work[6]=0x00000000;<br/> ^~~~~~~~~~~<br/>...</div><br/>then I tried by replacing the dll with the one from the CUDA Toolkit, and I got the same error than while running poclbm I built :<br/><div class="codeheader">Code:</div><div class="code"> File "poclbm.py", line 5, in <module><br/> File "pyopencl\__init__.pyc", line 3, in <module><br/> File "pyopencl\_cl.pyc", line 12, in <module><br/> File "pyopencl\_cl.pyc", line 10, in __load<br/>ImportError: DLL load failed: La procÚdure spÚcifiÚe est introuvable.</div><br/>So the problem come from OpenCL dll from Nvidia !<br/><br/>I checked _cl.pyd with dependency walker, if I'm correct (this is the first time I use this tool), some functions are missing in the OpenCL.dll from Nvidia :<br/><div class="codeheader">Code:</div><div class="code">clSetUserEventStatus (pyopencl-0.92\src\wrapper\wrap_cl.hpp(1051,31))<br/>clCreateUserEvent (pyopencl-0.92\src\wrapper\wrap_cl.hpp(1062,20))<br/> (pyopencl-0.92\src\wrapper\wrap_cl.hpp(1063,32))<br/>clCreateSubBuffer (pyopencl-0.92\src\wrapper\wrap_cl.hpp(1165,22))<br/>

(pyopencl-0.92\src\wrapper\wrap_cl.hpp(1460,27))<br/>clEnqueueCopyBufferRect (pyopencl-0.92\src\wrapper\wrap_cl.hpp(1496,27))</div><br/>In the file OpenCL.dll in poclbm_py2exe.7z, those 6 functions exist !<br/><br/>I got the explication with a little more search on the net, with the confirmation on those two pages :<br/><a href="http://www.khronos.org/registry/cl/sdk/1.0/docs/man/xhtml/">http://www.khronos.org/registry/cl/sdk/1.0/docs/man/xhtml/</a><br/><a href="http://www.khronos.org/registry/cl/sdk/1.1/docs/man/xhtml/">http://www.khronos.org/registry/cl/sdk/1.1/docs/man/xhtml/</a><br/><br/>The 6 functions where added in OpenCL 1.1, and Nvidia OpenCL implements the version 1.0 !<br/><br/><b><del>So if I'm correct pyopencl won't work on Nvidia cards until Nvidia release an OpenCL 1.1 compliant Toolkit and driver.</del></b><br/>See the post below.<br/><br/>Note from <a href="http://developer.nvidia.com/object/opencl.html">http://developer.nvidia.com/object/opencl.html</a><br/><div class="quoteheader">Quote</div><div class="quote">On the same day Khronos Group announced the new OpenCL v1.1 specification update (June 14th, 2010), NVIDIA released OpenCL v1.1 pre-release drivers and SDK code samples to all GPU Computing registered
