IPS4o

IPS4o IPS4o stands for in-place parallel super scalar samplesort. It is a high performance comparison sorting algorithm designed for modern multicore CPUs. It combines samplesort partitioning, cache efficient block movement, and parallel execution while keeping extra memory usage small. The algorithm is useful when comparison sorting is required but ordinary quicksort or mergesort does not make full use of hardware parallelism. Problem Given an array $A$ of $n$ comparable elements,...

In Place Radix Sort

In Place Radix Sort In place radix sort sorts keys by digits while avoiding a full auxiliary output array. It keeps only small bucket metadata, such as counts, offsets, and next write positions. The common form is MSD based. At each digit position, the algorithm partitions the current subarray into digit buckets, then recursively sorts each bucket by the next digit. Problem Given an array $A$ of keys whose digits...
