Workflows

This experiment has been executed using:

• Model: Decision Tree regressor (test.yaml)
• n_samples: 8 (number of ALYA simulations to be run)
• Nodes used in the MN5 supercomputer: 4
• ALYA_PROCS = 56

Adapted version of a workflow used in CAELESTIS for mechanical testing simulation which was developed by Riccardo Cecco (Workflows and Distributed Computing Group, BSC) with the guidance of Gerard Guillamet (Dual Technologies Research Group, BSC) and Aravind Sasikumar (AMADE Research UDG).

Sensitivity Analysis to identify the material properties governing the structural failure of an open-hole test

Introduction

The certification of composite structures in the aeronautical sector follows a building-block pyramid approach, in which structural complexity, material uncertainties, and computational cost increase progressively across scales. To reduce reliance on extensive experimental campaigns, high-fidelity finite element simulations are increasingly employed for virtual testing. ...

K-means COMPSs application

COMPSs Matrix Multiplication resourceUsage profiling example.

MN5 MSIZE=20 BSIZE=768 7 Nodes (6 workers) (--num_nodes=7 --worker_in_master_cpus=0).

• Total number of tasks: 20^3 = 8000
• Maximum code parallelism: 20^2 = 400
• Total cores: 112*6 = 672
• Maximum utilisation: 400 / 112 = 3,57 Nodes

Lysozyme in water full COMPSs application run at MareNostrum IV, using full dataset with two workers

Sample workflow template that combines simulations with data analytics. It is not a real workflow, but it mimics this type of workflows. It illustrates how COMPSs invokes binaries. It can be extended to invoke MPI applications.
