Matrix Multiplication with Objects

Matrix multiplication is a binary operation that takes a pair of matrices and produces another matrix. Given a square matrix A of size MSIZE × MSIZE blocks and a square matrix B of the same size, the result C = A × B is computed block-wise. Each matrix is divided into MSIZE² blocks of BSIZE × BSIZE ...

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). The workflow ...

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. ...

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
