- detailed notes at https://github.com/EESSI/meetings/wiki/Brainstorm-meeting-software-deployment-Nov-24th-2021
- relevant for both building and testing software

- existing example bot by Kenneth available at https://github.com/boegel/boegelbot/tree/main/app can be used as a starting point for this GitHub App
- Next pilot will have a
versionsdirectory, and variant symlinksmodulesandsoftwarein the root, which can be controlled by site admins. - Terje: won't this cause any issues for software that links against software with thesoftwaresymlink in the path? - This should not happen, as the modulefiles will have the real path.- Kurt: be careful with (variant) symlinks and hierarchical module schemes, as this can lead to weird issues.
- We can test this with the next pilot, and if we really run into such issues, we can always remove the variant symlinks again.
- Kurt: be careful with (variant) symlinks and hierarchical module schemes, as this can lead to weird issues.
- Terje: should we document which verions can be built on top of the EESSI stack?
- You can work around them with EasyBuild by using an new compiler as build dependency (for example using GCC 8.x built with EasyBuild to build GCC 7.x, etc.)
- We can provide old compilers in the software layer (or even in the compat layer, side by side, if needed)
- Having a
Known issuespage in the documentation, listing such issues and possible workarounds, may be useful.
- Jörg: would be good to provide old GCC versions.
- We can even install those in Gentoo Prefix.
- We can go back if there is a need for it, but we don't want to support e.g. GCC 4.

- Quite a lot of interest! Therefore, we picked two weeks instead of one
- AWS announced some new instances this week:
- Graviton 3 (not available yet, only as preview)
-
G5ginstances with Arm Graviton2 CPUs and NVIDIA T4G Tensor Core GPUs
- Everybody agrees that this hackathon is a brilliant idea :-)
- If you plan to actively participate, please fill out the doodle: https://doodle.com/poll/xha7h6pawwuk5xc2
- CIUK is still taking place as in-person conference, but face masks are required
- Jörg is planning to go, and mention EESSI where applicable
- Jaco: no news on setting up the EESSI consortium, work on this will be continued in 2022.
- Jaco: there will be an innovation lab in Groningen, with early access to new hardware. This will also be interesting for EESSI, as we can test and prepare software builds on the latest hardware.
