The next Python Exchange is happening soon!
Our Guest Panelist will be:
Kyle Chard
Kyle Chard is a Research Associate Professor in the Department of Computer Science at the University of Chicago. He also holds a joint appointment at Argonne National Laboratory. He received his Ph.D. in Computer Science from Victoria University of Wellington, New Zealand in 2011. He is a member of the ACM and IEEE, received the IEEE TCHPC Award for Excellence for Early Career Researchers in HPC, was part of the Globus team that won an R&D100 award, and received the New Zealand Top Achiever Doctoral Scholarship. He co-leads the Globus Labs research group, which focuses on a broad range of research problems in data-intensive computing and research data management. He leads NSF-funded projects related to distributed and parallel computing, scientific reproducibility, research automation, and cost-aware use of cloud infrastructure.
“Globus Compute: Managed Python Execution Across the Computing Continuum”
“Globus Compute is a distributed Function as a Service (FaaS) platform that enables flexible, secure, scalable, and high performance remote Python function execution.
Unlike centralized FaaS platforms, Globus Compute allows users to execute functions on heterogeneous remote computers, from laptops to leadership computing facilities. In this talk, Kyle will describe how Globus Compute can enable researchers to easily scale and execute their Python programs on remote computers. Examples showing how Globus Compute is being used in various applications across the national labs will be presented.”

“What we are doing to make Python faster”
Pablo Galindo Salgado
"Python 3.11 is faster than previous Python versions. This is the result of the effort of the Faster CPython collaboration, which is a team that Guido van Rossum started at Microsoft and that later some other contributors and core devs (including myself) joined as collaborators. In this discussion, I will go into detail on how we are making Python faster, what techniques are we using, what challenges are we facing, and what may be stored for future versions."

“Sustaining the HPC software ecosystem with Spack”
Todd Gamblin, Lawrence Livermore National Labs
Spack is an open source package management tool, written in Python, that simplifies the process of building and installing scientific software. It is used widely in the HPC community — by end users, HPC facility staff, and software developers who need to manage dependencies. Spack is very general; it is designed to allow packages to be built with many different versions, configurations, build options, and compiler flags, for CPU and GPU machines. This talk will give an overview of Spack, its community, and how enables users to be more productive.

“Python in particle accelerators”
Emanuele Laface
Python is a daily instrument in science for data analysis, modelling and computing in general. In this talk, I discuss the role of Python at the European Spallation Source, a particle accelerator facility for neutron production. I briefly describe the science that a neutron source can achieve and then my discussion will be focused on the use of Python in our laboratory. In particular, I talk about Python and Jupyter in the control system of the particle accelerator as a front-end to access the multiple systems used to archive data, query the accelerator devices, and simulate online the dynamics of the particle beam.

“The napari n-dimensional array viewer with Py-ART”
Draga Doncila Pop and Juan Nunez-Iglacias
Juan:
"I’m currently a Senior Research Fellow at Monash University in Melbourne, Australia. My scientific path started in genetics and biochemistry, continued through
computational biology and bioinformatics, then to image analysis — where I connected with the Scientific Python community and got hooked on open source development. I’ve
since become a core developer on scikit-image, co-authored the book Elegant SciPy, and co-founded the napari library for image visualisation, annotation, and analysis.
Draga:
"I am currently a PhD student working on an open source interactive interface for cell segmentation and tracking optimisation. I work part time as a software engineer
making contributions to open source software, and am a napari core developer.
I am passionate about scientific software, open source development and open research. I love sharing my knowledge with others and making software development accessible for
all."

“Enabling the Open Radar Science Community with Py-Art”
Max Grover and Zachary Sherman, Argonne National Laboratory
Maxwell Grover Max is a software developer at Argonne National Laboratory, primarily working with the Atmospheric Radiation Measurement (ARM) User Facility, focused on developing open-source tools to improve how we work with climate and weather datasets. He is one of the primary developers for the Python ARM radar toolkit (Py-ART) and the Atmospheric Data Community Toolkit (ACT). While his background is in meteorology and atmospheric science, his passion is software engineering, working with scientists to find ways to improve their software tools and general data workflows, advocating for open science practices.
Zachary Sherman Zach is a software developer at Argonne National Laboratory working between ARM and the Geospatial Computing Innovations, and Sensing (GCIS). Zach works primarily as a developer on Py-ART as well as the Atmospheric Community Toolkit (ACT). Zach started with little software knowledge, but overtime developed a passion for open source software and developing tools to help individuals with their research utilizing Python and many tools in the Scientific Python Stack as well as utilizing and teaching coding practices such as continuous integration, PEP8 and more.

PyIron — an integrated development environment (IDE) for scientific workflows at scale.
Jan Janssen
Jan Janssen As part of his PhD, he developed the open-source workflow framework pyiron, which couples atomistic simulation codes written in Fortran, C or C++ to a modern jupyter-based user interface, data storage and job management. With this combination pyiron enables rapid prototyping and up-scaling of simulation protocols for exascale computing and is applied for parameter studies in materials science ranging from uncertainty quantification for density functional theory to the prediction of melting temperatures for interatomic potentials and beyond.
