The organization of data is clearly of great importance in the design of high performance algorithms and architectures. Although there are several landmark papers on this subject, no comprehensive treatment has appeared. This monograph is intended to fill that gap. We introduce a model of computation for parallel computer architec- tures, by which we are able to express the intrinsic complexity of data or- ganization for specific architectures. We apply this model of computation to several existing parallel computer architectures, e.g., the CDC 205 and CRAY vector-computers, and the MPP binary array processor. The study of data organization in parallel computations was introduced as early as 1970. During the development of the ILLIAC IV system there was a need for a theory of possible data arrangements in interleaved mem- ory systems. The resulting theory dealt primarily with storage schemes also called skewing schemes for 2-dimensional matrices, i.e., mappings from a- dimensional array to a number of memory banks. By means of the model of computation we are able to apply the theory of skewing schemes to var- ious kinds of parallel computer architectures. This results in a number of consequences for both the design of parallel computer architectures and for applications of parallel processing.
If you like Roger McGough, you'll love Jonathan Lord! "Dead Mice On Your Doorstep" is a poetic journey through 25 years of love, loss, and introspection. Laugh with the poet's old self. Smile at his memories of perfume and kisses. Feel his pain. Live the terror of his nightmares. Read back over the times he looked inside himself and see that there were times when he loved himself (maybe a little too much?) and times when he most certainly did not. There's no promise that you'll like every poem given within this cover. Some, like the dead mice left on a doorstep, may leave you feeling a little uncertain - even though the gift was made with love.
