ips4o (DuckDB/Polars parallel samplesort) native extension for Quill
Project description
quill-fastsort-ips4o
Native C++ extension that exposes the ips4o
in-place parallel super scalar samplesort (the same kernel used internally by
DuckDB and Polars) as a Python module for the QuillSort
dispatcher. QuillSort's runtime auto-picker measures latency per (dtype, size)
bucket and chooses between its Rust parallel-MSD-radix kernel and this ips4o
samplesort kernel; C++ assists Rust, it does not replace it. The module installs
as the top-level Python name quill_fastsort_ips4o and exposes in-place sort
entry points (sort_i64, sort_u64, sort_i32, sort_u32, sort_f64,
sort_f32) that operate on contiguous numpy ndarrays and release the GIL for
the duration of the sort.
