A flexible environment for an efficient exploitation of vector features in electric and magnetic analysis

The authors present a vector environment, built around a reconfigurable data structure and a library of solver routines, devised for an efficient exploitation of vector features of computers to speed up magnetic analysis codes. The tests performed for the definition of the environment are reported and commented on, and the final results showing significant speedups in real magnetic analysis cases on a selected vector machine are presented and discussed. It is concluded that the use of the vector environment defined by the ITPLUS storage and the APPEAL library of solver routines has proven practical and successful as a way to allow users to efficiently exploit vector architectures, while protecting them from the need of large recoding efforts and of deep knowledge in computer architecture features and performances. >
