Building and Managing ACCESS UM Executables

This page aims to provide a top-level list of use cases and links to documentation about building and managing ACCESS UM executables.

UM Versions

• Status of local implementation of UM versions (MartinDix et al.)

ACCESS NWP build jobs

• ACCESS NWP Build Documentation Page (AsriSulaiman et al.)
• APS1 Build Documentation Page
• APS2 Build Documentation Page

Using Prebuilds

• Using prebuilds with rose suites

Interactive debugging

• Totalview debugging in Rose-Cylc suites (MartinDix)

---

Older material from this point onwards

Building UM small executables

• Building UM small executables (UM 8.2 and earlier) (MartinDix)

Rose build jobs

• aa054 standard Rose build job for vn8.5 + GA6 branch (IanCampbell)
• aa059 and aa063 Stand alone Build Suites (MichaelNaughton & IanCampbell)

Building with code modifications

• where to make code modifications, and how to run fcm make2 interactively to re-build
• committing changes to um svn branches
• creating patches for passing changes back to Met Office

Pre-builds vs full builds

• ScottWales UMUI pre-builds

Compiler settings and versions

• debug / safe / reproducible / high
  • what do they mean?
  • what do we need?

Notes

• rmifdf -- Until recently, UM versions used ifdef's for different physics options instead of run-time switching, leading to requirement for separate executables for each application. Physics ifdefs have been mostly (completely) removed from vn8.5 (8.6) onwards, and coupled-model ifdefs will be removed at vn9.0, so from this point on a single executable for each model version can be used for all ACCESS applications.
• GA branches -- For GA versions up to GA5, building from special GA branches was required, as GA code was not fully included in UM trunk; from vn8.6 GA6 onwards full GA versions will be available in UM trunk versions.
• A shared SVN repository will be used for UM versions from later in 2014, which will replace the access-svn UM repository for developments from that version onwards (but not respectively for earlier versions). A shared Rose experiment repository is also planned.
