Clearly it doesn't work at present. We have no OpenCL support whatsoever.
If would be possible to implement certain MDX functions in OpenCL, and
create Java wrappers for them using JOCL. That would be an interesting
project. I would tend to focus on the MDX functions/operators that tend to
be performance-intensive, such as Filter, Order, TopCount/BottomCount,
See http://jira.pentaho.com/browse/MONDRIAN-874 for a discussion of
parallelism. Many of the issues raised in that bug would relate to an OpenCL
