Use case: Transfer and optimization of CFD calculations workflow in HPC environment
Authors: Ján Škoviera (National competence centre for HPC), Sylvain Suzan (Shark Aero)
Shark Aero company designs and manufactures ultralight sport aircrafts with two-seat tandem cockpit. For design development they use popular open-source software package openFOAM [1]. The CFD (Computational Fluid Dynamics) simulations use the Finite Elements Method (FEM). After the model is created, using a Computer-Aided Design (CAD) software, it is divided into discrete cells, so called “mesh”. The simulation accuracy depends strongly on mesh density with the computational and memory requirements rising with the 3rd power of the number of mesh vertices.
For some simulations the computational demands can be a limiting factor. Workflow transfer into High-Performance Computing (HPC) environment was thus undertaken, with a special focus on the investigation of computational tasks parallelization efficiency for a given model type.
METHODS
Compute nodes with 2x6 cores Intel Xeon L5640 @ 2,27GHz, 48 GB RAM and 2x500 GB were used for this project. All calculations were done in a standard HPC environment using Slurm job scheduling system. This is an acceptable solution for this type of workloads where no real-time response, nor immediate data processing is required.
For the CFD simulations we continued to use OpenFOAM & ParaView version 9 software packages. Singularity container was used for calculation deployment, having in mind potential transfer of the workload to another HPC system. The speed-up gained from just straight away transfer to HPC system was approximately 1.5x compared to a standard laptop.
PARALLLEZIATION
Parallelized task execution can increase the speed of the overall calculation by utilizing more computing units concurrently. In order to parallelize the task one needs to divide the original mesh into domains - parts that will be processed concurrently. The domains, however, need to communicate through the processor boundaries i.e. domain sides where the original enclosing mesh was divided. The larger the processor boundary surface is, the more I/O is required in order to resolve the boundary conditions. Processor boundary communication is facilitated by the distributed memory Message Passing Interface (MPI) protocol, and the distinction of difference between CPU cores and different compute nodes is abstracted from user. This leads to certain limitations on efficient usage of many parallel processes, since overly parallelized job executions can be actually slower due to communication and I/O bottlenecks. Therefore, the domains should be created in a way that minimizes the processor boundaries. One possible strategy is to divide the original mesh only in co-planar direction with the smallest side of the original enclosing mesh. By careless division into domains the amount of data to be transferred increases beyond reasonable measure. If one chooses to use mesh division in multiple axes, one also creates more processor boundaries.
Figure 1: Illustration of mesh segmentation. The encoling mesh is represented by the transparent boxes
The calculations were done in four steps: enclosing mesh creation, mesh segmentation, model inclusion and CFD simulation. The enclosing mesh creation was done using the blockMesh utility, the mesh segmentation step was done using the decomposePar utility, the model inclusion was done using the snappyHexMesh program, and the CFD simulation itself was done using SimpleFoam. The most computationally demanding step is snappyHexMesh. This is understandable from the fact that while in CFD simulation the calculation needs to be done several times for every edge of the mesh and every iteration, in the case of model inclusion one creates new vertices and deletes old ones based on the position of vertices in the model mesh. This requires creation of an “octree” (partitioning of three-dimensional space by recursively subdividing it into eight octants), repeated inverse search, and octree re-balancing. Each of these processes is N*log(N) in the best case scenario, and N2 in the worst case, N being the number of vertices. The CFD itself scales linearly with number of edges, i.e. “close to” linearly with N (only spatially proximate nodes are interconnected).2 We developed a workflow that creates a number of domains that can be directly parallelized with the yz plane (x being the axis of the aircraft nose), which simplifies the decision making. After inclusion of a new model, one can simply specify the number of domains and run the calculation minimizing the human intervention needed to parallelize the calculation.
RESULTS AND CONCLUSION
The relative speedup of the processes calculation is mainly determined by limited I/O. If the computational tasks are well below I/O bounding, the speed is inversely proportional to the number of domains. In less demanding calculations, i.e. for small models, the processes can be easily over-parallelized.
Figure 2: Dependence of real elapsed time on the number of processes for snappyHexMesh and simpleFoam. In the case of simpleFoam the time starts to diverge for more than 8 processes, since the data trafic overcomes the paralellization advantage. Ideal scaling shows the theoretical time needed to finish the calculation, if the data trafic and processor boundary condition resolution was not involved.
Once the mesh density is high enough, the time to calculate the CFD step is also inversely proportional to the number of parallel processes. As shown in the second pair of figures with twofold increase in mesh density, the calculations are below I/O bounding even in the CFD step. Even though the CFD step is in this case comparatively fast to the meshing process, the calculation of long time intervals could make it the most time consuming step.
The aircraft parts design requires simulations of a relatively small models multiple times under altering conditions. The mesh density needed for these simulations falls into medium category.
When transferring the calculations to the HPC environment, we had to take into account the real needs of the end user in terms of model size, mesh density and result precision required. There are several advantages of using HPC:
The end user is relieved of the need to maintain his own computational capacities.
Even when restricted to single thread jobs the simulations can be offloaded to HPC with high speed up, making even very demanding and precise calculations feasible.
For even more effective calculations a simple way of utilizing parallelization was determined, for this particular workload. Limitations of parallel runs for the given use case and conditions were identified. The total increase in speed that was reached in practical conditions is 7.3 times. The speed-up generally grows with the calculation complexity and the mesh precision.
Summer School: From Supramolecular Chemistry to Structural Biology by Multiscale Modelling Methods
Computer simulations have become a valuable tool for expanding our knowledge in many areas. Steadily increasing performance of supercomputers or even desktop computers allows us to simulate bigger systems or achieve higher accuracy employing routine simulations. However, proper predictions can only be obtained if correct models and theoretical approaches are employed. Thus, this course aims to provide essential foundations for performing computer simulations and how to avoid typical errors coming from misunderstanding employed approximations. The lectures will span the vast range of molecular modeling methods addressing problems from supramolecular chemistry to structural biology. The course will be composed of theoretical lectures complemented by practical sessions exercising typical simulation techniques in each discipline. This course is particularly suited for bachelor and masters students who are interested in continuing their studies into a PhD and a career in research.

On May 9, the "birthday celebration" of the European Union took place in Bratislava's Stara tržnica. The Europe Day event was organized by the Office of the European Parliament and the Representation of the European Commission. The team of the National Competence Centre for High-Performance Computing also presented its activities on Europe Day. On Europe Day, we commemorate the Schuman Declaration which started modern European integration and led to the creation of the current European Union as a unique peaceful and democratic project. Schuman Declaration which started modern European integration and led to the creation of the current European Union as a unique peaceful and democratic project.

Information stands of EU member states, the European Parliament and the European Commission were available to the general public. The event also featured the stand of the National Competence Centre for High-Performance Computing (NCC for HPC). The NCC team presented the activities and services of the National Competence Centre for HPC. Through an interactive demonstration of simulations of potential drugs against the Covid-19 disease, we brought the participants closer to what calculations supercomputers can be used for. During the event, Lucia Demovičová spoke on stage and presented the National Competence Centre for HPC to the public. She explained how the competence centre can help scientists, researchers, and also small and medium-sized entrepreneurs. She also presented successful examples of cooperation with the private and public sector and invited participants to our information stand.
„Cooperation between countries based on peace, freedom and mutual respect is not a matter of course even today. Let us therefore appreciate that Slovakia can be part of the European Union, which protects these values. Since European elections await us next year, the Europe Day celebrations will also be an evaluation of what European democracy has brought us in practice over the past four years. The events will focus on specific results of the European Parliament's work in areas such as EU energy independence, internet security, defense of democracy, support for Ukraine and fair transformation of the economy in the fight against climate change," said the head of the EP Office in Slovakia, Robert Sermek.
„Every year on May 9, we celebrate the achievements and unity of Europe. The signing of the Schuman Declaration in 1950 laid the foundations for cooperation between European countries and today's European Union. Slovaks do not want to be foreigners in Europe, it is our home, and therefore Europe Day is also a great opportunity to celebrate our common European identity across all member states. The symbolism of this day confirms the unity of Europeans and at the same time expresses the beauty of a number of different cultures, languages and traditions that benefit the entire European Union and all Europeans",“ uviedol vedúci Zastúpenia Európskej komisie na Slovensku Vladimír Šucha.

We would like to invite you to a popularization lecture focused on Natural Language Processing. NLP refers to a branch of computer sciences—and more specifically the branch of artificial intelligence or AI—concerned with giving computers the ability to understand text and spoken words in much the same way human beings can. This method is also used by currently very popular ChatGPT.
The aim of the lecture is to provide a comprehensive view on NLP and outline the potential of its use for small and medium-sized enterprises. Marek Šuppa from the Comenius University and Slido company will introduce you to NLP.
During the lecture we will talk about:
What are modern language models and how are they created?
How these models can be used practically?
How much does it cost to train and operate such models?
Aké sú očakávania od NLP v budúcnosti.
The event will take place online on April 3 from 5:00 p.m. The number of places is limited and registration mandatory.

Research project: Use of wave energy for the third generation WEC
On February 2nd, an online presentation of the research project Use of wave energy for the third generation WEC (Wave energy converter) took place in the premises of the Computing Centre of the Slovak Academy of Sciences. The hybrid event was organized by niore Energy s.r.o. and the National Competence Centre for High Performance Computing.
Company niore Energy s.r.o. is focused on the production and storage of clean energy. Experts from niore Energy s.r.o.
are plan to become part of the world's electrical grid solution and contribute to global goals by turning ocean waves into electricity and utilizing water for energy storage. This patent-pending concept is based on a floating ring on the ocean's surface. This ring enables the transformation of oscillating motion into rotary motion, which is the motion that generates the most electricity efficiently. The bigger the diameter of the ring, the more sturdy it is against ocean waves, and the more energy we can collect from a broader surface area. Energy Storage, which is also a rotating device floating on the ocean's surface, will serve as the cornerstone for the storage of clean energy, by converting extra electricity into kinetic energy. You can find more information about Energy HUB technologies HEREDuring the presentation of this research project, M. Novák also gave a demonstration of their technology.
Research project Use of wave energy for the third generation WEC is supported by Norwegian grants and the state budget of the Slovak republic.
