WebJul 9, 2024 · In this post, I introduce a design and implementation of a framework within RAPIDS cuDF that enables compiling Python user-defined functions (UDF) and inlining them into native CUDA kernels. This framework uses the Numba Python compiler and Jitify CUDA just-in-time (JIT) compilation library to provide cuDF users the flexibility of Python … WebApr 7, 2024 · We'd write the code such that any incoming numpy or pandas types would be converted to cudf.dtype objects and then would follow a single codepath thereafter.

WebWe can apply more complex functions to rolling windows to rolling Series and DataFrames using apply. This example is adapted from cuDF’s API documentation. First, we’ll create an example Series and then create a rolling object from the Series. ser = cudf.Series( [16, 25, 36, 49, 64, 81], dtype='float64') ser. small vac and mop
