Although that libclicd thingy looks outdated and/or incomplete,
I like the testapps/list_platforms.c utility. It would be nice to have something
like that in (a possible) wrapper ICD loader package (the
/usr/lib/libOpenCL.so).

AMD has a similar (more verbose) utility called 'clinfo'.
I have experimentally removed the /usr/lib/libOpenCL.so file from the Intel sdk,
installed it alongisde the AMD sdk and tried what these utils would output.
The result looks quite nice, see http://codepad.org/NGaPsYbr
