CiTIUS showcases three proposals at IEEE Cluster 2025, a leading forum in High Performance Computing (HPC)

Researchers from CiTIUS, the Research Centre for Intelligent Technologies at the University of Santiago de Compostela and part of the CIGUS Network — an initiative led by the Galician Government to bring together research centres with recognised scientific excellence — are taking part in the 27th edition of the IEEE Cluster conference, one of the world’s premier forums in the field of High Performance Computing (HPC), held this year in Edinburgh.

This event brings together experts from academia, research institutions, and industry to explore the latest developments in computing architectures for cluster systems — interconnected groups of computers that operate in coordination as if they were a single machine, significantly increasing computational power.

In a landscape where quantum computing is emerging as one of the major technological challenges of our time, and portable heterogeneous programming is showing great promise for the future of HPC, the CiTIUS team has presented three new scientific contributions aimed at facilitating the development of next-generation heterogeneous and quantum solutions.

The first was presented by researcher Silvia Rodríguez Alcaraz, in collaboration with Francisco F. Rivera (CiTIUS), David L. Vilariño (USC), and Rubén Laso (University of Vienna). This work focuses on performance evaluation of portable heterogeneous solutions in systems that combine conventional processors (CPUs) with graphics processing units (GPUs).

Researcher Francisco Javier Cardama presented the results of two additional studies in Edinburgh, carried out in collaboration with Tomás Fernández Pena (CiTIUS) and Miguel Leal (USC). The first of these is NetQMPI, a Python-based library for programming distributed quantum systems, inspired by MPI (Message Passing Interface) — a supercomputing standard that enables processors to work in parallel by sending and receiving messages.

The third proposal, SYCL QPU, is a framework designed to allow classical processors and simulated quantum units to work together within a single unified programme.

These scientific contributions reflect the ongoing commitment of CiTIUS to stay ahead of the curve in tackling the major technological challenges of the future. In a rapidly evolving field where the line between fundamental research and practical application continues to blur, the work presented at IEEE Cluster 2025 helps lay the groundwork for a new generation of solutions that seamlessly integrate classical, heterogeneous, and quantum computing, bringing emerging technologies closer to real-world applications that benefit both science and society.
