This package contains two versions of the TRISTAN PIC code, a vectorized fortran77 version which runs on Cray vector machines, and an MPL version which runs on MasPars. The MPL version implements a particle migration strategy in which particles migrate across the MasPar's processor as the simulation proceeds, in order to ensure that no global router communications are required. <description><url>http://sdcd.gsfc.nasa.gov/ESS/exchange/contrib/macneice/pic-tristan.html </url> <reference><url>http://sdcd.gsfc.nasa.gov/ESS/papers/pic_perform.ps</url> <contact>Peter MacNeice <keywords>particle in cell method; application program <category>application <publication-date> <environment>Vectorized Fortran77, Cray; MPL, Maspar <method> <application>magnetosphere simulations <comments> </urc>
