Simulation Manager

Simulation Manager contains list of future simulation jobs.

• These are neighbors of completed simulations, varied by one option (dimension).
• Each future job has an assigned priority score, built from statistic analysis of neighbor completed simulation.
  • NOTE: Initial simulations are selected randomly, to seed future job generation.

Simulation Manager contains list of un-analyzed simulation jobs.

• These are simulation runs that do not have the full range of statistics or scores.

Simulator

Simulation system requests new job from Simulation Manager

• Receives initial simulation condition parameters
  • This may or may not include specific particle/atom information
  • If not, atoms are generated
    • Atoms are randomly placed
    • Atoms are energy minimized to remove overlaps from random generation
• Generates GROMACS binary format topology.
• Loops:
  • Passes topology to GROMACS to perform short simulation step (1 second?)
  • Load trajectory (atom motion) data generated by GROMACS
  • Analyze data for bond formation
    • Create new bonds (molecules)
      • This includes atom exchange
  • Update topology
  • Loop until full simulation time has been generated
• Submit trajectory data to Simulation Manager
• Submit basic statistics (bond creation) to Simulation Manager

Analysis

Analysis system requests new analysis job

• Receives simulation trajectory data
• Perform statistical analysis
• Analyze statistics to produce scores
• Submit statistical analysis to Simulation Manager
• Submit scores to Simulation Manager

Simulation Manager

Simulation Manager receives scores

• Generate priority for neighboring simulations
  • Certain score types may emphasis work on specific neighbors
• Submit neighboring simulations to future job queue
