[petsc-users] ViennaCL

[Karl Rupp]

Hi Mohammad,

there is a first interface to ViennaCL in the next-branch already. 
Configure with
   --download-viennacl
   --with-opencl-include=/path/to/OpenCL/includes
   --with-opencl-lib=/path/to/libOpenCL.so
and then use
   -vec_type viennacl
   -mat_type aijviennacl
as runtime options.

As this resides in next, it is still work in progress. If you encounter 
any problems during installation, please let us know. Also, OpenCL 
typically shows larger latency than CUDA, so you should have at least 
100k unknowns to see any performance gain.

Best regards,
Karli
