10:30 Simplification of quantum circuits with toolchains from the Eviden Quantum Learning Machine (QLM) Quantum Simulator

Through the tools provided by the Eviden QLM quantum simulator, it is possible to rewrite circuits. This technique consists of automatically compressing sequences of consecutive one-qubit gates into a universal pattern. In this intervention, it will be detailed how this technique has been applied in a quantum circuit and how it has been possible to reduce the number of quantum gates of a qubit. In addition, the results obtained after the execution in different IBM backends will be shown and how the reliability of the circuit is improved. Everything from a single environment, that of QLM.

11:00 HPC in quantum era

This 2023, quantum computing is evolving faster than ever. Last year, Europe selected six sites to host the first European Quantum Computers, which will be added to other projects like the future quantum computers in CESGA, BSC and Ikerbasque. However, the quantum community is not waiting to have real quantum hardware before investigating new algorithms and solutions.

Quantum emulators can be used to start experimenting with quantum software. On a small scale, algorithms can be executed on a laptop, but complicated solutions will need the use of CUDA or MPI acceleration in an HPC environment. In this talk, we will focus on this last case.

Convergence of HPC/AI and Cloud.

14:00 Cloud and HPC Convergence: Flux for Job Management on Kubernetes

Adoption of cloud technologies by high performance computing (HPC) is accelerating, and HPC users want their applications to perform well everywhere. While container orchestration frameworks provide advantages like resiliency, elasticity, and declarative management, they are not designed to natively enable application performance to the same degree as HPC workload managers and schedulers. In this talk, we present our effort in promoting Cloud and HPC convergence, an effort that spans computing platforms and institutions. Specifically, we target Kubernetes platforms with the introduction of the Flux Operator and the Fluence plugin scheduler, both based on the Flux open-source HPC resource manager and job scheduler. We also describe the challenges we faced when shifting from traditional HPC to Kubernetes, and what it takes to run workflow natively on such platforms.

14:30 Cloud-Native Supercomputing: Exploring New Technologies for High-Performance Computing

As cloud-native technologies continue to advance, researchers and engineers in high-performance computing (HPC) are beginning to explore how these technologies can be used to build more scalable, reliable, and efficient supercomputers. In this talk, we will explore some of the latest technologies being used in cloud-native supercomputing, and discuss how they are being integrated into Kubernetes, the de facto standard for container orchestration.
One of the most exciting new technologies for cloud-native supercomputing is dynamic resource allocation (DRA), which has recently been merged into Kubernetes upstream. DRA allows users to dynamically allocate resources based on their application’s requirements, making it possible to optimize resource usage and reduce costs.
Another important technology is the container device interface (CDI), which provides a standardized way for containers to access devices like GPUs and FPGAs. CDI is critical for running high-performance computing workloads on cloud-native infrastructure, as it allows applications to take advantage of specialized hardware.
We will also discuss Kueue, a Kubernetes-native queuing controller that enables users to easily manage complex workloads with dependencies and priorities. Finally, we will provide updates on the MPI operator, which automates the deployment and scaling of MPI applications in Kubernetes clusters.
By leveraging these new technologies, cloud-native supercomputing promises to unlock new levels of scalability and efficiency for HPC workloads, making it possible to tackle even the most demanding scientific and engineering challenges.

EESSI workshop.

15:10 – 17:00 Streaming scientific software: an introduction to EESSI

Have you ever wished that all the scientific software you use was available on all the resources you had access to without having to go through the pain of getting them installed the way you want/need? The European Environment for Scientific Software Installations (EESSI – pronounced “easy”) is a common stack of scientific software installations for HPC systems and beyond, including laptops, personal workstations and cloud infrastructure. In many ways it works like a streaming service for scientific software, instantly giving you the software you need, when you need it, and compiled to work efficiently for the architecture you have access to.

In this tutorial, we’ll explain what EESSI is, how it is being designed, how to get access to it, and how to use it. We’ll give a number of demonstrations and also give access to a resource where you can try EESSI out for yourself.
