Tensor Comprehensions(TC) is a notation based on generalized Einstein notation for computing on multi-dimensional arrays.

TC leverages [Halide](https://github.com/halide/Halide), a domain specific language specialized for image processing with C++, Cuda and OpenCL backends.

TC apparently achieve 80% throughput of handwritten loops.
