Patience is a Virtue: Revisiting Merge and Sort on Modern Processors
Summary: Revisits in-memory sort/merge with Patience Sort, CPU-aware tweaks. P3 Sort (Ping-Pong Patience+Sort) and ping-pong merge; competitive with Quicksort and Timsort on random and almost-sorted data; P3 replacement selection for logs with bounded disorder.
