A portable coding strategy to exploit vectorization on combustion simulations
Fabio Banchelli, Guillermo Oyarzun, Marta Garcia-Gasulla +4
The complexity of combustion simulations demands the latest high-performance computing tools to accelerate its time-to-solution results. A current trend on HPC systems is the utili…
Dynamic load balance of chemical source term evaluation in high-fidelity combustion simulations
Guillem Ramírez-Miranda, Daniel Mira, Eduardo J. Pérez-Sánchez +4
This paper presents a load balancing strategy for reaction rate evaluation and chemistry integration in reacting flow simulations. The large disparity in scales during combustion i…
Performance assessment of CUDA and OpenACC in large scale combustion simulations
Guillermo Oyarzun, Daniel Mira, Guillaume Houzeaux
GPUs have climbed up to the top of supercomputer systems making life harder to many legacy scientific codes. Nowadays, many recipes are being used in such code's portability, witho…
Parallel SFC-based mesh partitioning and load balancing
Ricard Borrell, Guillermo Oyarzun, Damien Dosimont +1
Modern supercomputers allow the simulation of complex phenomena with increased accuracy. Eventually, this requires finer geometric discretizations with larger numbers of mesh eleme…
HPC compact quasi-Newton algorithm for interface problems
A. Santiago, M. Zavala-Aké, R. Borell +1
In this work we present a robust interface coupling algorithm called Compact Interface quasi-Newton (CIQN). It is designed for computationally intensive applications using an MPI m…
Heterogeneous CPU/GPU co-execution of CFD simulations on the POWER9 architecture: Application to airplane aerodynamics
R. Borrell, D. Dosimont, M. Garcia-Gasulla +6
High fidelity Computational Fluid Dynamics simulations are generally associated with large computing requirements, which are progressively acute with each new generation of superco…
