This project had its beginnings in the Fall of 1980. At that time Robert Wagner suggested that I investigate compiler optimi­ zation of data organization, suitable for use in a parallel or vector machine environment. We developed a scheme in which the compiler, having knowledge of the machine's access patterns, does a global analysis of a program's operations, and automatically determines optimum organization for the data. For example, for certain architectures and certain operations, large improvements in performance can be attained by storing a matrix in row major order. However a subsequent operation may require the matrix in column major order. A determination must be made whether or not it is the best solution globally to store the matrix in row order, column order, or even have two copies of it, each organized differently. We have developed two algorithms for making this determination. The technique shows promise in a vector machine environ­ ment, particularly if memory interleaving is used. Supercomputers such as the Cray, the CDC Cyber 205, the IBM 3090, as well as superminis such as the Convex are possible environments for implementation.

This book encompasses part of the papers presented at the Fifth International Symposium on Motor Control held in Varna, Bulgaria from 10 to 14 June 1985. The Motor Control Symposia organized in Bulgaria became tradition following the successful initiation of Professor Gydikov and his collaborators of the previous four meetings (Sofia, 1969, Varna, 1972, Albena, 1976, Varna, 1981). More than 140 scientists participated in the last Symposium, 40 from East Europe, 15 from West Europe, 15 from USA and Canada. These Symposia established an opportunity for encounter of prom­ inent scientists from allover the world, representatives of different schools and mainstreams. The participation of R. Granit, W. R. Ashby, B. C. Matthews, V. S. Gurfinkel, E. V. Evarts etc., is to be mentioned. The main topics of the Symposium included: 1) Motor Unit Activity; 2) Reflex Control of Movements; 3) Central Control of Movements; 4) Posture Control; 5) Locomotion; 6) Arm Movement; 7) Motor Control Models. 43 oral presentations and 103 posters were reported, 36 of them being presented in this volume. The presented papers deal with the complex mechanisms of movement and posture control, investigations of considerable interest in recent years. This interest was prompted by the huge biological importance of the motor activity as a most common mechanism of adaptation to the environment. Motor activity is also inadvertently involved in various fields of human practice: occupational activities, including extreme conditions, motor handicaps, sports, bioprosthetic devices, bionics, robotics etc.
