Three ways to share a QPU: Scheduling strategies for hybrid Quantum-HPC applications
Marco Cipollini, Simone Rizzo, Sergio Iserte +21
The paper investigates three scheduling approaches—time‑based multiplexing, dynamic resource management, and workflow decomposition—to efficiently allocate quantum processing units…
Portable Acceleration of Learning With Errors KEMs for Post-Quantum Cryptography
Tiziana Liberati, Nitin Shukla, Simone Rizzo +5
The transition to post-quantum cryptography (PQC) is driving demand for implementations that can meet the computational requirements of real-world applications. Among the proposed…
Is RISC-V Ready for Massively Parallel Astrophysical Codes?
Jenny Lynn Almerol, Nitin Shukla, Federico Ficarelli +5
We present a performance and portability evaluation of three well-established astrophysical production codes, namely iPIC3D, PLUTO, and OpenGadget3, on a Sophgo SG2044 RISC-V proce…
GPU Acceleration of Learning With Errors KEMs Using OpenACC for Post-Quantum Cryptography
Tiziana Liberati, Nitin Shukla, Matteo Barbieri +5
Shor's algorithm proved that asymmetric cryptographic protocols based on the integer factorization and discrete logarithm problems are no longer safe in a world with large-scale qu…
Assessing Performance and Porting Strategies for Gravitational -Body Simulations on the RISC-V-Based Tenstorrent Wormhole\textsuperscript{\texttrademark}
Jenny Lynn Almerol, Elisabetta Boella, Mario Spera +1
While RISC-V-based accelerators were initially designed with artificial intelligence applications in mind, they are increasingly being recognized as promising platforms for high pe…
