1. TRANSIMS Version 5 Software Architecture January 20, 2011 David Roden – AECOM

2. Topics  Goals and objectives  Standard template library extensions  Code organization and consolidation  Program service hierarchy  Typical program linkages  Path building and simulation services  Multiple threads, DLL, and MPI 1/20/2011 Chicago RTSTEP TRANSIMS Model 2

3. Goals and Objectives  Make the code easier for new programmers to understand, modify and build upon –Standard Template Library –Centralize codes, standardize and automate processing –Expand and simplify programmer support services  Make the code safer and more robust –Eliminate re-defined data classes and application differences  Improve performance and reduce run times –Utilize multiple cores and MPI clusters  Create DLL services for linkages to other software 1/20/2011 Chicago RTSTEP TRANSIMS Model 3

4. Standard Template Library Extensions  Custom data containers  C++ STL –vectors, maps, iterators, streams, and strings  Encapsulate and extend STL methods –string  String Case insensitive comparisons, trimming, parsing, type conversions, and type safe printf-like formating –streams  Message, Print, Write, XML Managed output to the screen and print files –char array  Buffer Dynamic character arrays for binary and text file input and output –time  Dtime Day-time data object with input and output formatting 1/20/2011 Chicago RTSTEP TRANSIMS Model 4

5. Code Organization and Consolidation  Enumerations consolidated into one place with static conversion services (text  code, code  text)  Standard containers and iterators defined in a central TypeDefs library  SysLib re-grouped and organized as files, data classes, read and write methods, and a series of program services  Control key structure and processing methods standardize, simplify, and automate user interface and help functions 1/20/2011 Chicago RTSTEP TRANSIMS Model 5

6.
