cudahook

A library for intercepting CUDA runtime calls with LD_PRELOAD and dlsym.

Compiling

We use hook mechanisms that are specific to GNU/Linux.

$ make

should work, although you need to edit the CUDAPATH variable in the Makefile if CUDA is not installed to /usr/local/cuda

Using

$ LD_PRELOAD=/path/to/cudahook/libcudahook.so ./your-program

will run the CUDA program and intercept the following runtime calls:

• cudaConfigureCall
• cudaLaunch
• cudaRegisterFunction
• cudaSetupArgument

At the moment, we use this information to print out information about invoked kernels.
