Vectorization of MHD Equilibrium and Stability Codes

摘要

An MHD equilibrium code (SELENE) and a stability code (ERATO-J) are extensively used for the analysis of ideal MHD beta limit of a tokamak plasma. High efficiency is required for the analysis of experimental data and the design of the next step fusion experimental devices. In the report, the methods of vectorization are described as well as the basic equations and numerical methods. Vectorization reduces the comptational time to about a third through a quarter of the original version on Fujitsu VP-100. (ERA citation 12:044780)
