Stacks

Leader: André Sailer
🌐 spi.web.cern.ch

In the context of the EP-SFT activities, the Stacks team provides coherent software stacks for the use of LHC experiments, CERN users, and user around the world (LCG Software Stacks, further information), and develops the Key4hep software ecosystem. These software stacks consist of several packages — including Monte Carlo generators, Machine Learning tools, Python modules — all available for a large number of compilers, operating systems, and hardware architectures.
The SPI team is also responsible to run the Librarians and Integrators Meeting (LIM), a forum bringing together librarians of all the LHC and other experiments to share experiences about software stack provisioning.
The Stacks team also supports the Jenkins-based build orchestrations used for the nightly and release builds of the Stacks, Geant4, and CVMFS teams.
