New York: ACMCONTENTS- .dcl/.icl: the Clean modules of the analyzer- Spec.icl/.dcl: test cases for the corresponding Clean module- *.prj.default: original project files for the main program and the testcases. Must be renamed to .prj to compile. This is because the clean compilermodifies those files, but we don't want the modification under versioncontrol.- bash_completion.d: source this file in your .bashrc to get simplecommand-line completion for the mtasks command.- test: source code of the TestFramework, needed to run the unit tests- boxes: some brainstorming how skylines are appended and stacked- programs: example programs to demonstrate the analyzer- More information on how to compile and run this program can be found in README.txt- We ran into some problems when trying to organize the source code in subdirectories, because compile errors of the Clean compiler does not reflect module structure well enough for integration with external tools. That is why all source code is in one directory.SHORT SUMMARYIn this paper we present a static analysis for costs of higher-order workflows, where costs are maps from resource types to simple functions over time. We present a type and effect system together with an algorithm that yields safe approximations for the cost functions of programs.
