LIKWID: Installation Hint

If you set the likwid install path in config.mk and the last character is a slash, likwid-pin will not run with the following error message:

ERROR: ld.so: object '~/helper/likwid-2.2-inst' from LD_PRELOAD cannot be preloaded: ignored.

Delete the last slash and do
make clean && make && make install

and likwid-pin should work fine.

Disable Fermi Cache

To disable Fermi L1 Cache in CUDA just compile with: -Xptxas -dlcm=cg

Any idea on how to do this with OpenCL?
