Computational models and resource allocation for supercomputers

J. Mauney, D.P. Agrawal, Y.K. Choe, E.A. Harcourt, S. Kim, W.J. Staats
1989 Proceedings of the IEEE  
The computational needs of a program must be cast in terms of the computational model supported by the supercomputer, and this must be done in a way that makes effective use of the machine's resources.  ...  There are several different architectures used in supercomputers, with differing computational models. These different models present a variety of resource allocation problems that must be solved.  ...  Because memory access on a processor is much faster than inter-PE communication, finding a data-mapping scheme that enables concurrent memory reference is crucial for fast computation.  ...
