I may be wrong but AFAIK getting into the Top 500 requires meticulous
configuration of all sorts of parameters. If you want to get any good
performance at all, be prepared to invest a couple of weeks.

Not me, sorry. Is there a website of NVIDIA? Or does documentation
come with the code? Usually I'd have a look directy at the code (i.e.
search for cudaSetDevice()).
