Accelerating the Dutch Atmospheric Large-Eddy Simulation (DALES) model with OpenACC
Lucas Esclapez, Laurent Soucasse, Caspar Jungbacker +5
This paper presents the GPU porting through OpenACC directives of the Dutch Atmospheric Large-Eddy Simulation (DALES) application, a high-resolution atmospheric model. The code is…
Bringing Auto-tuning to HIP: Analysis of Tuning Impact and Difficulty on AMD and Nvidia GPUs
Milo Lurati, Stijn Heldens, Alessio Sclocco +1
Many studies have focused on developing and improving auto-tuning algorithms for Nvidia Graphics Processing Units (GPUs), but the effectiveness and efficiency of these approaches o…
Comprehensive analysis of the Apertif Fast Radio Burst sample: similarities with young, energetic neutron stars
Inés Pastor-Marazuela, Joeri van Leeuwen, Anna Bilous +9
Understanding the origin of fast radio bursts (FRBs) has become the main science driver of recent dedicated FRB surveys. Between July 2019 and February 2022, we carried out ALERT,…
The Apertif Radio Transient System (ARTS): Design, Commissioning, Data Release, and Detection of the first 5 Fast Radio Bursts
Joeri van Leeuwen, Eric Kooistra, Leon Oostrum +49
Fast Radio Bursts must be powered by uniquely energetic emission mechanisms. This requirement has eliminated a number of possible source types, but several remain. Identifying the…
A fast radio burst with sub-millisecond quasi-periodic structure
Inés Pastor-Marazuela, Joeri van Leeuwen, Anna Bilous +31
Fast radio bursts (FRBs) are extragalactic radio transients of extraordinary luminosity. Studying the diverse temporal and spectral behaviour recently observed in a number of FRBs…
Apertif, Phased Array Feeds for the Westerbork Synthesis Radio Telescope
W. A. van Cappellen, T. A. Oosterloo, M. A. W. Verheijen +87
We describe the APERture Tile In Focus (Apertif) system, a phased array feed (PAF) upgrade of the Westerbork Synthesis Radio Telescope which has transformed this telescope into a h…
Chromatic periodic activity down to 120 MHz in a Fast Radio Burst
Inés Pastor-Marazuela, Liam Connor, Joeri van Leeuwen +34
Fast radio bursts (FRBs) are extragalactic astrophysical transients whose brightness requires emitters that are highly energetic, yet compact enough to produce the short, milliseco…
ESiWACE2 Services: RSE collaborations in Weather and Climate
Gijs van den Oord, Victor Azizi, Alessio Sclocco +5
We present the collaborative model of ESiWACE2 Services, where Research Software Engineers (RSEs) from the Netherlands eScience Center (NLeSC) and Atos offer their expertise to cli…
Lessons learned in a decade of research software engineering GPU applications
Ben van Werkhoven, Willem Jan Palenstijn, Alessio Sclocco
After years of using Graphics Processing Units (GPUs) to accelerate scientific applications in fields as varied as tomography, computer vision, climate modeling, digital forensics,…
A bright, high rotation-measure FRB that skewers the M33 halo
Liam Connor, Joeri van Leeuwen, L. C. Oostrum +37
We report the detection of a bright fast radio burst, FRB\,191108, with Apertif on the Westerbork Synthesis Radio Telescope (WSRT). The interferometer allows us to localise the FRB…
Repeating fast radio bursts with WSRT/Apertif
L. C. Oostrum, Y. Maan, J. van Leeuwen +40
Repeating fast radio bursts (FRBs) present excellent opportunities to identify FRB progenitors and host environments, as well as decipher the underlying emission mechanism. Detaile…
Real-Time RFI Mitigation for the Apertif Radio Transient System
Alessio Sclocco, Dany Vohl, Rob V. van Nieuwpoort
Current and upcoming radio telescopes are being designed with increasing sensitivity to detect new and mysterious radio sources of astrophysical origin. While this increased sensit…
The Apertif Monitor for Bursts Encountered in Real-time (AMBER) auto-tuning optimization with genetic algorithms
Klim Mikhailov, Alessio Sclocco
Real-time searches for faint radio pulses from unknown radio transients are computationally challenging. Detections become further complicated due to continuously increasing techni…
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…
