  4. Topic 1Agent-BasedSimulation CSS599 Talk

  5. Macro-versusMicro-SimulationTop-downversusBottom-up Approach Macroscopic/Top-down Microscopic/Bottom-up Focus on an emergent, collective group behavior of many objects Molecular level Pedestrian/vehicle level Difficulty verification Calibration required Fewer real data available to the public (e.g. congestion at a traffic light) Scalable computation required Easy parallelization No partition required (yet object-CPU mapping needed) • Mathematical models • Schroedinger eq. (for wave) • Euler eq. (for fluid dynamics) • Easy verification • Mathematical verification • Easy access to public data (e.g. traffic flow) • Inaccurate enough • No support of object-interaction • Difficulty in parallelization • Space partition/mapping etc. CSS599 Talk

  6. MolecularDynamicsConventional Top-down Approach t=0 t=100 t=200 for ( int i = 0; i < N; i++ ) for ( int j = 0; j < I; j++ ) if ( sqrt( pow( x[i] – x[j], 2.0 ) + pow( y[i] – y[j], 2.0 ) ) < forceCutoff ) { ax[i] += fOver2 * ( x[i] – x[j] ); ax[j] -= fOver2 * ( x[i] – x[j] ); ay[i] += fOver2 * ( y[i] – y[j] ); ay[i] += fOver2 * ( y[i] – y[j] ); } i = molecular_range_begin[rank]; i < molecular_range_end[rank]; i++ ) MPI_Allreduce( ax, tmp_ax, N, MPI_DOUBLE, MPI_SUM, MPI_COMM_WORLD); MPI_Allreduce( ay, tmp_ay, N, MPI_DOUBLE, MPI_SUM, MPI_COMM_WORLD); computer 0 computer 1 Computer 2 CSS599 Talk

  12. Agent-BasedTransportSimulationParallelized byZachMaandpresentedatWSC2015 Road network converted to an adjacency list Programmability Execution performance Vehicle drives converted to agent migration CSS599 Talk

  13. Collision-Free Agent MigrationPresented at FedCSIS/JAWS 2017 • Sequential migration • Upper-left agents have a higher priority than lower-right agents. • Parallel migration • All agents can migrate at once. • We need some prioritization. MATSim Traffic simulation Greedy parallel migration Location-ordered migration Direction-ordered migration Sequential migration collision another direction Distributed termination detection required 5 ordered migrations 4 ordered migration direction CSS599 Talk

  14. Our FutureGoals Investigating what parallel-programming features attract scientists who are not necessarily computing specialists: • Parallelizing ABM applications of our collaborators. • Developing benchmark testsets that cover various agent behaviors. CSS599 Talk

  15. Topic 2Agent-BasedData Analysis CSS599 Talk

  16. Topic 2:Agent-BasedBigDataHow different from conventional approach when counting triangles in a graph for example MapReduce, Spark, and Storm Agent-based Big Data Analytics actively move over data. Only necessary portionofdatacanbeexamined. Data can maintain its structure. Code is written from the driver’s viewpoint. • Analytics stay passive to receive data. • All data must be examined. • Data must be flattend to feed. • (1,2), (2,1), (2,3), (3,2), (2,4), (4,2), (2,5), (5,2), (3,4), (4,3), (4,5), (5,4) 1 • (1, [2]), (2, [1,3,4,5]), (3, [2,4]), (4, [2,3,5]), (5, [2,4]) • [(1,2), -], [(1,3), 2], [(2,3), -], [(2,3), 4], [(2,4), -], [(2,4),3], • [(2,4), 5], [(2,5), 4], … 2 5 • (2,3) [-,4]  (2,3,4), (2,4) [-,3,5] -> (2,4,3), (2,4,5)… • (2,3,4), (2,3,4), (2,3,4), (2,4,5), (2,4,5).. • (2,3,4), (2,4,5) 3 4 CSS599 Talk

This in turn means that we need to populate an agent at each place at the beginning, which is a big overhead. CSS599 Talk
