Book Description
Parallel Sorting Algorithms explains how to use parallel algorithms to sort a sequence of items on a variety of parallel computers. The book reviews the sorting problem, the parallel models of computation, parallel algorithms, and the lower bounds on the parallel sorting problems. The text also presents twenty different algorithms, such as linear arrays, mesh-connected computers, cube-connected computers. Another example where algorithm can be applied is on the shared-memory SIMD (single instruction stream multiple data stream) computers in which the whole sequence to be sorted can fit in the respective primary memories of the computers (random access memory), or in a single shared memory. SIMD processors communicate through an interconnection network or the processors communicate through a common and shared memory. The text also investigates the case of external sorting in which the sequence to be sorted is bigger than the available primary memory. In this case, the algorithms used in external sorting is very similar to those used to describe internal sorting, that is, when the sequence can fit in the primary memory, The book explains that an algorithm can reach its optimum possible operating time for sorting when it is running on a particular set of architecture, depending on a constant multiplicative factor. The text is suitable for computer engineers and scientists interested in parallel algorithms.

Book Description
We propose a parallel algorithm, called adaptive bitonic sorting, which runs on a PRAC, a shared-memory multiprocessor where fetch and store conflicts are disallowed. On a $P$ processors PRAC, our algorithm achieves optimal performance $TP = O(N \log N)$, for any computation time $T$ in the range $\Omega (\log[superscript]{2} N) \leq T \leq O(N \log N)$. Adaptive bitonic sorting has also a small constant factor, since it performs less than $2N \log N$ comparisons, and only a handful of operations per comparison.

Book Description
The papers in this volume were presented at SWAT 92, the Third Scandinavian Workshop on Algorithm Theory. The workshop, which continues the tradition ofSWAT 88, SWAT 90, and the Workshop on Algorithms and Data Structures (WADS 89, WADS 91), is intended as an international forum for researchers in the area of design and analysis of algorithms. The volume contains invited papers by L.G. Valiant (Direct bulk-synchronous parallel algorithms), A.A. Razborov (On small depth threshold circuits), G. Gonnet (Efficient two-dimensional searching), and E. Welzl (New results on linear programming and related problems), together with 34 selected contributed papers. Contributions cover algorithms and data structures in all areas, including combinatorics, computational geometry, data bases, parallel and distributed computing, and graphics.
