Dear All,
After several days I did a certain progress, but still can't make my
Macports installed python work with pyopencl on Snow Leopard. And I'm going
crazy...
First I run ./configure.py with certain options specified in one ticket:
./configure.py --boost-inc-dir=/opt/local/include
--boost-inc-dir=/usr/local/include --boost-lib-dir=/opt/local/lib
--boost-lib-dir=/usr/local/lib --boost-python-libname=boost_python
--boost-thread-libname=boost_thread --cl-libname=''

Then I run the python setup.py install. Here what I've got:

It seems to me that it was successfully compiled, because there were only

ld: warning: in

Because the specified directory contain libboost_python.dylib and
libboost_python.a compiled on the Snow Leopard system.
After that I run python and I've got error:

Please if anybody knows the solution or any ideas - spend a few minutes and

Thank you,

Hi,
I just downloaded, compiled and installed pyopencl from the git tree.
I am using AMD's opencl sdk for cpu's and it is working alright. When
I tried to run the demo.py example in the pyopencl distribution, it
threw an error.
Traceback (most recent call last):
File "demo.py", line 8, in <module>
ctx = cl.Context()
pyopencl.LogicError: Context failed: invalid platform
It appears that these examples have to be modified to specifically
select the device as now AMD's sdk ships with an ICD.
Here's the corresponding C example.

I'm interested in doing some investigation into what performance I could
obtain by implementing various signal processing algorithms in GPU. Any
suggestion on an environment I could setup to try this? I'm thinking of a
simulation environment running under linux, without using a real gpu.
Hi community,
I'm new here and I'm starting to learn openCL and pyopencl seems very
attractive. I want to make a simple program that will compute lines of
the pascal triangle. How can I copy a buffer into another one ? On the
reference API from Khronos, there's a function called
clEnqueueCopyBuffer, but I don't find the equivalent on the pyopencl API.
Am I missing something or is this function not yet implemented ?
Best regards,
Nicolas Bonnel
this seems like a stupid question but :
I am trying to port a PyCUDA project to PyOpenCL, and can't find the
equivalent to "memcpy_htod" and "memcpy_dtoh" in PyOpenCL. I need to
be able to modify the contents of a device buffer from the host after
the device buffer has been initialized. Is this possible ?

A few things I noticed about this:
1) After the install the setuptools in:
/System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/setuptools/
is trashed
2) Which causes the easy_install in /usr/bin to break
3) Neither py.test nor pytools is installed so the test doesn't run
After installing setuptools again and creating a symbolic from
/usr/local/bin/easy_install to /usr/bin/easy_install, I installed pil (this
may be for PyCUDA), py and pytools. Now the test runs with the following
error message:

I'm trying to install pyopencl on OSX 10.6. I've installed Boost 1.41
