Dataflow Dataflow Vocabulary Send and Get GuiVars Scheduler Module Dataport Datapipe UI Send and Get GuiVars Scheduler Dependencies loops: send_intermediate

Network Design

Module: Algorithm + UI Algorithm User Interface Module: wrapper Function Reusability User Interface Buttons, tabs, slides, text entry, … Hidden state Module: wrapper Infrastructure: setup, shutdown Execute 1) Why am I being told to execute 2) Get data from ports 3) Update UI variables 4) Invoke algorithm 5) Send data out ports

Net Files and State Net File Create modules Create datapipes Set UI values Environment variables to create general purpose nets SCIRUN_DATA SCIRUN_DATASET Human editable… but be careful! Datasets can also be written out and read in… more on that tomorrow

I/O, Bridging, and Thirdparty Read/Write modules for SCIRun format “convert” programs for importing / exporting external data formats Packages = projects Internal External: bridging Store external libraries in Thirdparty Independent of SCIRun standards Externally maintained
