OpenDIEL – Introduction
• OpenDistributiveInteroperableExecutableLibrary• UsesMPI(MessagePassingInterface)• Cooperationbetweenlooselycoupledmodules• Outputssingleexecutable• Crucialincombiningmultiplesimulationscenario!!
OpenDIEL – Manual
• Userhastoprovide:• Modules (Executable,Cmodule,FortranModule,Executable)• ConfigurationFile (LibConfig)• Driver (C- File)
OpenDIEL – Enhancements
• ModMaker• Timer• I/OImprovements• FortranSupport
ModMaker – Introduction
• Transformatsourcecodelevel• Nolongercompilesintostandaloneexecutable• Compilesintoalibrary

ModMaker – PatternMatching
• Twooptionswereconsidered• Matchingbycharacter• Matchingbystring
• Matchingbystringisused• Simplicity• Similarperformance
n=stringsize,s=documentsize(measuredincharacter)
ModMaker – SyntacticFreedom
• Locating• Spaces• VariableDeclaration
ModMaker – Modularization
• FunctionTitle• Statement• Variable
• BaseCheck (line,tokenList,prevSep,nextSep,msgBundle,replacement,returnValue)
ModMaker – Testing
• Tester.c• Dummy“IEL.h”
