With deep regret, we announce that on January 13, 2024, Prof. Dr. hab. Krzysztof Belczyński, an employee of the Nicolaus Copernicus Astronomical Center of the Polish Academy of Sciences in Warsaw and Universe@Home project author, passed away.

Professor Belczyński had been associated with our institute since 1995. It was then that he began his research on novae stars, followed by the synthesis of stellar populations and the processes of formation of compact objects - neutron stars and black holes. He obtained his doctorate in physical sciences with a specialization in astronomy in 2001. Between 2000 and 2009, he completed numerous scientific internships at foreign research centers. From 2009 to 2017, he was associated with the Astronomical Observatory of the University of Warsaw. In 2010, he obtained his postdoctoral degree, and in 2014 he was awarded the title of professor of physical sciences. Since 2017, he had been employed at the Nicolaus Copernicus Astronomical Center of the Polish Academy of Sciences in Warsaw as a professor.

Professor Belczyński was a theoretical astrophysicist, specializing in the study of compact objects, such as black holes, neutron stars, and white dwarfs. He is the author of over 200 peer-reviewed scientific publications, published in renowned international journals. He led numerous research projects, including the MAESTRO NCN grant and the MASTER FNP program, and supervised doctoral students. His research contributed significantly to the advancement of understanding the physics of compact objects and their evolution. His work is crucial for understanding the nature of gravitational wave sources, which are currently one of the most important topics of scientific research.

Hello GPUGRID! We are deploying a new app "PYSCFbeta: Quantum chemistry calculations on GPU". It is currently in testing/beta stage. It is only on Linux at the moment. The app performs quantum chemistry calculations. At the moment we are using it specifically for Density Functional Theory calculations: http://en.wikipedia.org/wiki/Density_functional_theory These types of calculations allow us to accurately compute specific properties of small molecules. The current test work units have a runtime of the order 1hr (very much dependent on the GPU speed and size of molecule). Each work unit currently contains 1 molecule with ~10 configurations. The app will not work on GPUs with compute capability less than 6.0. It should not be sending them to these cards but I think at the moment this functionality is not working properly. The work-units require a lot of GPU memory. It works best if the work-unit is the only thing running on the GPU. If other programs are using significant GPU memory the work-unit might fail. Looking forward to hearing feedback from you. Steve
