OpenCL installation on Ubuntu 12.10 (pyrit don't see opencl GPU device)

Hello!

System: Ubuntu 12.10 64-bit, E-450 with HD6320M card.

1. Installation 13.4 driver was correct (http://wiki.cchtml.com/index.php/Ubuntu_Quantal_Installation_Guide#Installing_Proprietary_Drivers_a....).

2. Installation AMD APP SDK v2.8 was correct too (http://developer.amd.com/download/AMD_APP_SDK_Installation_Notes.pdf).

3. When I try to check: pyrit list_cores it shows only:

The following cores seem available...

#1: 'CPU-Core (SSE2)'

#2: 'CPU-Core (SSE2)'

Where am I wrong?

it report both CPU and GPU so problem must be in pyrit. from installation guide of pyrit it seems like you must install extension module into pyrit so it can take advantage of GPU http://pyrit.googlecode.com/files/cpyrit-opencl-0.3.0.tar.gz

nou thank you!

OpenCL works. I also try to run Blender with opencl support (by runinng command: CYCLES_OPENCL_TEST=true blender). Blender shows compute devices correctly.

hi,

In case you are interested in using cycles in blender, please go through: http://devgurus.amd.com/message/1287924#1287924

OPEN_CYCLES has been having some compilation  troubles, and AMD is actively looking into them. Meanwhile there are some other rendering engines, that are doing remarkable work using AMD GPUs.
