Book Description
CPU times for nonlinear resistive MHD calculations are very strongly dependent on the input variables. Although some regions of parameter space can be studied very cheaply, the conditions that correspond to Tokamak plasmas are extremely time consuming to study. Unfortunately, it is not possible to extrapolate reliably from the easy cases to the interesting regime. In recent years we have improved the efficiency of our codes by two orders of magnitude. As a result it is now feasible for us to run some realistic Tokamak cases on a CDC 7600. An additional factor of four reduction in run time is obtained by going to the CRAY-1 where the most time consuming routines are vectorized. This last factor makes a program of systematic studies feasible.

Book Description
Major advances in computing are occurring at an ever-increasing pace. This is especially so in the area of high performance computing (HPC), where today's supercomputer is tomorrow's workstation. High Performance Computing Systems and Applications is a record of HPCS'98, the 12th annual Symposium on High Performance Computing Systems and Applications. The quality of the conference was significantly enhanced by the high proportion of keynote and invited speakers. This book presents the latest research in HPC architecture, networking, applications and tools. Of special note are the sections on computational biology and physics. High Performance Computing Systems and Applications is suitable as a secondary text for a graduate-level course on computer architecture and networking, and as a reference for researchers and practitioners in industry.
