Recently, employing photonic quantum computers for machine learning purposes has gotten more attention, hence the need for efficient simulation of photonic quantum machine learning is key in this research area. To ease simulation, automatic differentiation of photonic quantum circuits is essential, for which a Piquasso implementation is presented.

78. Exploring the complex structures of the disordered region of CFTR protein using AlphaFold

Erzsébet Suhajda (Semmelweis University, Budapest University of Technology and Economics)

Lecture

Cystic fibrosis (CF) is a hereditary disorder caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) protein, resulting in the loss of function of this ion channel in the plasma membrane of epithelial cells. CFTR is composed of two transmembrane domains and two intracellular nucleotide-binding domains (NBDs), with the disordered R-domain wedged between them....

79. Synchronization transitions on connectome graphs with external force

Dr Géza Ódor (EK-MFA Centre for Energy Research)

Lecture

We have investigated the synchronization transition of the Shinomoto-Kuramoto model on networks of the fruit-fly and two large human connectomes. This model contains a force term, thus is capable of describing critical behavior in the presence of external excitation. By numerical solution we determined the crackling noise durations with and without thermal noise and showed extended...

70. Results and experiences from LUMI running CFD workloads

István Zoltán Reguly (Pázmány Péter Catholic University, Hungary)

15/05/2023, 15:15

Lecture

In this talk, I will present my experiences building a range of Computational Fluid Dynamics applications on LUMI that use a variety of parallelization approaches, such as HIP, OpenMP offload, and SYCL. Given the relatively new AMD GPU platform, I discuss issues and limitations that affect development, debugging and performance analysis. I show a contrasting analysis of performance as a...
