So you aborted it? That is some progress ;-)

It may be that your GPU is too weak to run vectorized. I'll do some 
changes soon and let you know. In the mean time, try prepending your 
command line with GWS=0 as in "GWS=0 ./john --test 
--format=office2007-opencl" and you'll hopefully see some things 
happening. Please report the outcome of that.

Or if you feel like hacking around, edit opencl_office2007_fmt.c and 
force VF to 1 no matter what. Then edit opencl/office2007_kernel.cl and 
force "#define SCALAR" no matter what. Then recompile and try it out 
(also with GWS=0 for more verbosity).
