I do have some local changes from when Pat changed the version to 0.13, and
small change in spark that i think I was using to fix what Trevor's pom.xml
workaround was needed for.
I'll push them soon to the branch.

Subject: RE: Errors when 0.13.0 master or vcl
Hmm.. ok the viennacl-omp tests failing is strange. But actually I have not
spent as much time on that stuff.
I'll be looking into this later this afternoon..
Suneel, could you send ur errors and arch details please?
I'll also send out a c++ snippet with some raw vcl matrix ops just to make sure
that gpus are working.
Andrew.. I know u said u didn't see any gpu usage?
Ok I'll get on this later this afternoon... it's a paycheck morning for me.

It's not reliable; I've had the -Pviennacl build pass and fail, and the
-Pviennacl-omp build fail but not pass.
