Hi, I have an invitation to have some talk with the title Debian GNU/Linux for Scientific Research Abstract: Over the past decade, Enterprise Linux has dominated large-scale research computing infrastructure. However, recent developments have sparked increased interest in community-led alternatives. Debian GNU/Linux, a long-standing choice among researchers for supporting scientific work, is experiencing a renewed interest for High-Throughput Computing (HTC) and High-Performance Computing (HPC) applications. This presentation will provide an overview of how Debian is being utilized to support scientific research and will include a case study showcasing the migration of HTC operations from Enterprise Linux 7 (EL7) to Debian. While I could talk about Debian Science and Debian Med in general it would be cool to reference to some real life examples where Debian is used in Science and what might be the reason to use Debian.
EDF (French electricity producer and provider, also present in many countries) has several calculation codes that run on supercomputers. These software are developed by the people from the Research and Development to do some simulation, modelling, ... in many fields: uncertainty treatment, simulation of complex systems, incompressible or expandable flow, stochastic control, hydraulics... [0]
Most supercomputers in use at EDF are currently running Debian.Also the workstations of people in the R&D department are equipped with a (very close) derivative of Debian.
Many of these calculation codes are free and can be found in Debian: openturns, stopt, code-saturne, syrthes, salome (formerly), astk (formerly). The first four ones are currently maintained in Debian-science or Debian-math.
At some point, EDF chose to homogenise its scientific computing by basing workstations and supercomputers on Debian [1]: there is a consistent Debian-based environment for scientific informatics.
Still, [1] is 13 years old, the strategy could evolve in the future.
I personally would like to stress the "we package what we use" aspect and the "we mentor upstream to merge competence of the program with packaging skills" idea. Any input would be welcome to cover more ideas. Kind regards Andreas.
