When testing GPU builds, always use -noprelims (otherwise it'll run a
--test=0 which takes ages). Use --help for other options.

I think the default is not testing any GPU formats. Try "./
-showtypes" for all available types. A type can be one or more single
formats, like "xsha512-cuda" or a whole class, like "cuda" or "opencl"
(or "gpu" which does both"

for doing this manually, add -wo:../jtrTestSuite/pw.dic

Or just "cd ../../jtrTestSuite" and "./jtrts.dat -noprelims -stoponerror
