Meluxina
LuxProvide’s supercomputer MeluXina was inaugurated in June 2021. MeluXina was built to serve a large variety of complex, data-driven workloads. Its design is forward-looking, responding to the convergence of simulation, modeling, data analytics and artificial intelligence.
MeluXina is based on the EVIDEN BullSequana XH2000 platform with a computing capacity of 18 PetaFlops per second, and counts on 20 PetaBytes of DDN storage. MeluXina is fully scalable due to its open and modular architecture, and delivers high sustained performance through its GPU AI accelerators.
Meluxina legend
The love story between the mermaid Melusina and Count Siegfried of Luxembourg is one of the country’s founding legends. LuxProvide’s supercomputer was named MeluXina after the magical creature, as it is water-cooled and also represents a founding brick in the Luxembourgish digital ecosystem.
WHAT IS A SUPERCOMPUTER?
A supercomputer is a powerful and advanced compute platform that is designed to perform complex calculations and process vast amounts of data at extremely high speeds. It represents the pinnacle of computational power and is used for solving large and complex problems in various domains.
Supercomputers are typically composed of thousands or even millions of processing units (CPUs, GPUs), interconnected by a high-speed network. They leverage parallel processing techniques, where multiple processors work together on different parts of a problem simultaneously, solving large and complex problems in shorter timeframes. This enables organizations to tackle computationally intensive tasks that would be infeasible or time-consuming for conventional computing environments.
Supercomputers are known for their exceptional processing speed, measured in floating-point operations per second (FLOPS) or more recently in terms of AI-specific operations per second (AIOPS) for machine learning workloads. The world’s fastest supercomputers can perform calculations at speeds in the range of petaflops (quadrillions of calculations per second) to exaflops (quintillions of calculations per second).

If all the humans on the planet were to make a calculation in one second, it would be necessary to
multiply the population of the Earth by more than two million to reach MeluXina’s capacity
MELUXINA ARCHITECTURE
SOFTWARE STACK AND CONTAINERIZED WORKLOAD
MeluXina has a rich software environment, enabling scientists and engineers to be rapidly operational and productive. It comprises hundreds of ready-to-use software tools for running scalable HPC, HPDA and AI workloads and for application development.
MeluXina’s software environment is built around several pillars:
Compilers, programming languages and tools for performance engineering

USING MELUXINA
MELUXINA, THE CLOUD-ENABLED SUPERCOMPUTER
We are engineering the MeluXina Cloud to provide gateways to our supercomputing platform, supporting your most intensive computational and data workflows.
The MeluXina Cloud is meant to host:
- interactive environments for building and running AI models
- container registries that deliver encapsulated, trusted applications to supercomputing container engines
- portals and APIs that will enable you to deploy applications tailored to your needs
- object-oriented interfaces to our data pools
A Kubernetes platform running on top of the MeluXina Cloud is in the works. It will link the supercomputing platform to flexible, cloud-native services, and empower scalable AI solutions.
