Enhancing SLMs for Sustainable Code Optimization in Radio-Astronomy
Elisa Chiarotto, Jingbo Li, P. Chris Broekema +1
Recent Large Language Models (LLMs) can produce and optimize complex code. We investigate the use of LLMs to generate and optimize code for large-scale sciences, focusing on radio…
Job-level Carbon and Water Footprint Estimation for HPC: Bias Assessment from Runtime to Full Life Cycle
Xi Chen, Chris Broekema, Rob van Nieuwpoort
High performance computing evaluation has traditionally focused on performance and energy, but these metrics alone cannot capture the sustainability cost of runtime configurations.…
Efficient Construction of Large Search Spaces for Auto-Tuning
Floris-Jan Willemsen, Rob V. van Nieuwpoort, Ben van Werkhoven
Automatic performance tuning, or auto-tuning, accelerates high-performance codes by exploring vast spaces of code variants. However, due to the large number of possible combination…
FAIRSECO: An Extensible Framework for Impact Measurement of Research Software
Deekshitha, Siamak Farshidi, Jason Maassen +3
The growing usage of research software in the research community has highlighted the need to recognize and acknowledge the contributions made not only by researchers but also by Re…
RSMM: A Framework to Assess Maturity of Research Software Project
Deekshitha, Rena Bakhshi, Jason Maassen +3
The organizations and researchers producing research software face a common problem of making their software sustainable beyond funding provided by a single research project. This…
Pulsar Searches with the SKA
L. Levin, W. Armour, C. Baffa +24
The Square Kilometre Array will be an amazing instrument for pulsar astronomy. While the full SKA will be sensitive enough to detect all pulsars in the Galaxy visible from Earth, a…
Auto-Tuning Dedispersion for Many-Core Accelerators
Alessio Sclocco, Henri E. Bal, Jason Hessels +2
In this paper, we study the parallelization of the dedispersion algorithm on many-core accelerators, including GPUs from AMD and NVIDIA, and the Intel Xeon Phi. An important contri…
Real-Time Dedispersion for Fast Radio Transient Surveys, using Auto Tuning on Many-Core Accelerators
Alessio Sclocco, Joeri van Leeuwen, Henri E. Bal +1
Dedispersion, the removal of deleterious smearing of impulsive signals by the interstellar matter, is one of the most intensive processing steps in any radio survey for pulsars and…
Discovery of Carbon Radio Recombination Lines in absorption towards Cygnus~A
J. B. R. Oonk, R. J. van Weeren, F. Salgado +100
We present the first detection of carbon radio recombination line absorption along the line of sight to Cygnus A. The observations were carried out with the LOw Frequency ARray in…
Detecting cosmic rays with the LOFAR radio telescope
P. Schellart, A. Nelles, S. Buitink +102
The low frequency array (LOFAR), is the first radio telescope designed with the capability to measure radio emission from cosmic-ray induced air showers in parallel with interferom…
The brightness and spatial distributions of terrestrial radio sources
A. R. Offringa, A. G. de Bruyn, S. Zaroubi +75
Faint undetected sources of radio-frequency interference (RFI) might become visible in long radio observations when they are consistently present over time. Thereby, they might obs…
LOFAR: The LOw-Frequency ARray
M. P. van Haarlem, M. W. Wise, A. W. Gunst +197
LOFAR, the LOw-Frequency ARray, is a new-generation radio interferometer constructed in the north of the Netherlands and across europe. Utilizing a novel phased-array design, LOFAR…
