Parallel Divide And Conquer, Per Brinch Hansen
Parallel Divide And Conquer, Per Brinch Hansen
Electrical Engineering and Computer Science - Technical Reports
We develop a generic divide and conquer algorithm for a parallel tree machine. From the generic algorithm we derive balanced, parallel versions of quicksort and the fast Fourier transform by substitution of data types, variables and statements. The performance of these algorithms is analyzed and measured on a Computing Surface configured as a tree machine with distributed memory.

Do Hypercubes Sort Faster Than Tree Machines?, Per Brinch Hansen
Electrical Engineering and Computer Science - Technical Reports
We develop a balanced, parallel quicksort algorithm for a hypercube and compare it with a similar algorithm for a binary tree machine. The performance of the hypercube algorithm is measured on a Computing Surface.
