simulation lifecycle

1. Birth
   • Create graph of components using Python configuration file
   • Partition graph and assign components to MPI ranks
   • Instantiate components
   • Connect components via links
   • Initialize components using their init() functions
   • Setup components using their setup() functions
2. Life
   • Send events
   • Manage clock and event handlers
3. Death
   • Finalize components using their finish() functions
   • Output statistics
   • Cleanup simulation, delete components

component lifecycle in SST

1. Pre-construction: define and partition components
2. Construction: call component constructors and parse parameters
3. initialize
   • Components send “init” events to each other over links. Discover neighbors, negotiate parameters, initialize data structures, etc.
   • Multiple rounds of communication until no more “init” events are sent
4. setup
   • Each component does its final setup and schedules initial events
5. run
   • Actual simulation (time begins)
   • Continues until a set time, or all components agree to finish
6. finalize
   • Simulation complete
   • Write statistics, free memory
