Re: small gpu load (poclbm.py, 3x6950 under ubuntu 11.04)

CPU usage is about 50%

I'm trying to install SDK 2.4

Code:

wget http://download2-developer.amd.com/amd/APPSDK/AMD-APP-SDK-v2.4-lnx64.tgz
sudo tar zxfv AMD-APP-SDK-v2.4-lnx64.tgz -C /opt
export LD_LIBRARY_PATH=/opt/AMD-APP-SDK-v2.4-lnx64/lib/x86_64/:$LD_LIBRARY_PATH
wget http://pypi.python.org/packages/source/p/pyopencl/pyopencl-0.92.tar.gz
tar zxfv pyopencl-0.92.tar.gz
cd pyopencl-0.92
./configure.py --cl-inc-dir=/opt/AMD-APP-SDK-v2.4-lnx64/include/ --cl-lib-dir=/opt/AMD-APP-SDK-v2.4-lnx64/lib/x86_64
make
sudo make install
cd poclbm
./poclbm.py

Code:

/poclbm$ ./poclbm.py
Traceback (most recent call last):
File "./poclbm.py", line 27, in
platforms = cl.get_platforms()
pyopencl.LogicError: clGetPlatformIDs failed: invalid/unknown error code

What am I doing wrong?
