On-site session for discussions and coding. The core team will be present and participants are welcome to join us at the venue.
A large fraction of computing workloads in high-energy and nuclear physics is executed using software containers. For physics analysis use, such container images often have sizes of several gigabytes. Executing a large number of such jobs in parallel on different compute nodes efficiently, demands the availability and use of caching mechanisms and image loading techniques to prevent network...
The EP-SFT Stacks team provides LCG software stack nightly builds for 50 different combinations of STACK and PLATFORM.
Historically, the publication of nightlies on CVMFS utilized a single machine, resulting in extended processing times that lasted until the end of the working day. To speed up the publication, and enable the distribution of a larger set of platforms every day, the LCG stack...
/cvmfs/software.eessi.io is the production CernVM-FS repository of the European Environment for Scientific Software Installations (EESSI, pronounced as "easy", see [eessi.io/docs][1]). After several pilot iterations, EESSI has released its first production software stack in the fall of 2023. The growing software stack already includes hundreds of software installations optimised for a...
CernVM-FS remains a central service for the distribution of the CMS Offline Software (CMSSW). Traditional use cases include the distribution of CMSSW releases and container images. It also plays a crucial role in the deployment of Integration Builds (IB) and pull request testing as part of the CMSSW CI/CD workflow.
In this contribution, we present three new use cases of CernVM-FS for CMS....
GSI is and has been operating a cvmfs instance for many years.
It is used primarily to make prerequisites for physics simulations and analysis of GSI and future FAIR experiments available on our compute cluster.
These include items such as precompiled executables, Spack packages, as well as Apptainer images.
The current cvmfs setup at GSI will be outlined in this talk.
