摘      要：GENASISBasics provides Fortran 2003 classes furnishing extensible object-oriented utilitarian functionality for large-scale physics simulations on distributed memory supercomputers. This functionality includes physical units and constants;display to the screen or standard output device;message passing;I/O to disk;and runtime parameter management and usage statistics. This revision–Version 2 of Basics–makes mostly minor additions to functionality and includes some simplifying name changes. New version program summary Program Title: SineWaveAdvection, SawtoothWaveAdvection, and RiemannProblem (fluid dynamics example problems illustrating GENASISBasics);ArgonEquilibrium and ClusterFormation (molecular dynamics example problems illustrating GENASISBasics) Program Files doi:http://***/10.17632/6w9ygpygmc.1 Licensing provisions: GPLv3 Programming language: Fortran 2003 (tested with gfortran 6.1.0, Intel Fortran 16.0.3, Cray Compiler 8.5.3) Journal reference of previous version: Computer Physics Communications, 196 (2015) 506 Does the new version supersede the previous version?: Yes Reasons for the new version: This version makes mostly minor additions to functionality and includes some simplifying name changes. Summary of revisions: Several additions to functionality are minor. Two new singleton objects are KIND_SMALL and KIND_TINY, for smaller sized numbers than those specified by the previously available KIND_DEFAULT. The class MeasuredValueForm can now handle some more complicated cases of unit string processing. The numerical values in the CONSTANT singleton have been updated to 2016 values [3], and CONSTANT and UNIT contain a few additional members. A new class TimerForm can be used to track the wall time occupied by various segments of code. The PROGRAM_HEADER singleton now contains an array member of this new class. With calls like [Figure presented] the user can initialize their own timers;on return iMyTimer contains the index of the newly initialized timer
