Exploring agent based models
From laptop to world class HPC
Who am I ?
Let me introduce myself
Arthur Brugiere
-
Finished my Master at the USTH (Vietnam)
-
Engineer on projects ANR ESCAPE & COMOKIT
-
Working on GAMA for 2 years
-
Mostly involved in Big Data, model exploration and High Performance Computing (HPC) usage
-
Should start a thesis next year
What's ESCAPE ?
Exploring by Simulation Cities Awareness on Population Evacuation
ESCAPE: city scale evacuation
-
Hazard: It never sticks to the plan
-
Environment: Roads and buildings turn into enemies
-
Human behavior: People do everything to make the plan fail
-
Evacuation plan: Organization(s) spend resources to help people
ESCAPE Framework
Why explore ?
Answer that kinds of questions
| What If 📥 | How To 📤 |
|---|---|
| An exit point is closed | Evacuate as soon as possible |
| Explosion of a factory in the Rouen industrial area | Evacuate the most non-autonomous people under resource constraints |
ABM* exploration is expensive and time consuming !
Let's do some maths :
For a simulation with 3 parameters with 10 values each 10^3 = 1.000 simulations * repetitions
Objective :
Explore the entire parameter space with a minimal number of simulations
How to explore these models easily ?
The full self-hosted solution
OpenMole
-
Free and open-source platform
-
Offers tools to run, explore, diagnose and optimize model
-
Distributed computing environments
-
Works with GAMA
OpenMole provide functions to explore diversity in input or output
| ESCAPE | OpenMole |

| How To | Pattern Space Exploration (PSE) |
| What If | Origin Space Exploration (OSE) |
Explaination of the PSE
What the Pattern Space Exploration is for ?
Explaination of the PSE
How the Pattern Space Exploration works ?
GAMA 
HPC
COMOKIT use-case
Context: OpenMole need a specific virtualizator (Singularity) to run GAMA
Problem: That virtualizator is not install on the HPC
--
Solution: Use a custom setup to optimize parallelization run with GAMA's headless tools
HCP pipeline
My PhD subject 🎓
Two main points in it
Co-modeling
Continue thesis subject from Dr. Huynh Quang Nghi*
Parallelization of simulation processing
Working on parallel multi-scale calculation, which may be appliable on HPC environments
