Parallel implementation of QRD algorithms on the Fujitsu AP1000

Zhou, B.B; Brent, Richard P


This report addresses several important aspects of parallel implementation of QR decomposition of a matrix on a distributed memory MIMD machine, the Fujitsu AP1000. They include: Among various QR decomposition algorithms, which one is most suitable for implementation on the AP1000? With the total number of cells given, what is the best aspect ratio of the array to achieve optimal performance? How efficient is the AP1000 in computing the QR decomposition of a matrix? To help answer these...[Show more]
