• Damian Alvarez (JSC, Germany)
• Davide Vanzo (Vanderbilt University)
• Fotis Georgatos (Illumina, UK)

Agenda

• (no agenda set)
• Q&A

Bart's stuff

• GCC with -ftree-vectorize has been merged
• Created new toolchains that do not have MPI but have the math libraries to allow lower level software installation
• Fotis suggests a different toolchain approach where MPI is replaced with a "fat toolchain". Just an idea...

Software stack on cloud burst

• Davide: How to seamlessly provide the software stack on containerized instances in the cloud for job bursting?
• Fotis: Bright Computing and GridEngine provide solutions for transparent cloud bursting (or they claim so)
• The whole stack or layers of the stacks can be containerized and deployed through docker registry (e.g. Artifactory)

Lmod delivery framework

• Fotis: It would be useful to share how different sites deploy Lmod on the clusters (e.g. RPM packaging) and how it is configured and customized
• Work together as an Lmod users interest group to define a common flexible framework that would simplify the Lmod installation and customization for different sites
• For example, Bright/Illumina collaboration: https://github.com/Bright-Computing/bic
• Bart: A very interesting new feature on Lmod is depends_on, which will be supported in EasyBuild 3.6.0
