Where is the cuda (.cu) files?

[alephman]

can I ask a stupid question: I don't see any .cu cuda files in tensorflow source code, how to use cocl to transform them into cl files?

[hughperkins]

• they have the suffix .cu.cc, otherwise bazel chokes
• they're in tensorflow/core/kernels

On the whole, I prefer first to try testing against Eigen, standalone, before trying in tensorflow. Tensorflow bulid is kind of heavy... There are some Eigen tests at https://bitbucket.org/hughperkins/eigen/src/e9caed055dff038f18fe6379a89098376d4a64eb/unsupported/test/cuda-on-cl/?at=eigen-cl
