Basic indexing (indexing by ints, slices, newaxes, and Ellipsis)
Most of Advanced indexing (except for some indexing patterns with boolean masks)
Data types (dtypes): bool_, int8, int16, int32, int64, uint8, uint16, uint32, uint64, float16, float32, float64, complex64, complex128
Most of the array creation routines (empty, ones_like, diag, etc.)
Most of the array manipulation routines (reshape, rollaxis, concatenate, etc.)
All operators with broadcasting
All universal functions for elementwise operations (except those for complex numbers)
Linear algebra functions, including product (dot, matmul, etc.) and decomposition (cholesky, svd, etc.), accelerated by cuBLAS and cuSOLVER
Multi-dimensional fast Fourier transform (FFT), accelerated by cuFFT
Reduction along axes (sum, max, argmax, etc.)
