[Bf-committers] Cuda 5.5 Release Candidate available

[Jürgen Herrmann]

I just had a look on the nvcc compiler options we use to compile cuda binaries.
First of all we still use --opencc-options that are ignored by nvcc 5.0 and 5.5 when compiling for sm_20 and up.
Maybe we should see if there are nvcc optimization options we can use to regain speed when using Cuda 5.0+.
