2. Agenda General BE/CO upgrade strategy for LS1 (Vito, 10') Changes to the development tools and infrastructure – Development tools (Niall, 15') – Development platforms (VPC, cs-ccr-devX) (Luigi 10’) – Ideas for Development outside the TN (Vito 5’) – Linux platforms (consoles, back-end and front-end) (Vito, 5’) Changes to widely used software libraries – Brief introduction (Katarina, 5') – CMW and JAPC (Wojtek, 20') – LSA/InCA (Greg, 10') – Controls Configuration DirService (Zere, 10') – SDDS (Chris, 10') 20-March-2013Vito Baggiolini2

3. Today Today’s focus is on changes to widely used software libraries where an action is required from the user community 20-March-2013Vito Baggiolini3

5. LS1 – a time for radical changes LS1 is the time to make radical changes, and we will ;-) – During the last 4 years of Run, we focused on operations – During LS1, we’ll focus on development/renovation/upgrades – We’ll do our best to minimize nuisance to operations, but … We’ll switch from Run mode to LS1 mode at Easter Why do we need to upgrade? – No more commercial support for old HW or SW – Security updates – Follow evolution of hardware (e.g. drivers for new CCC consoles) – New versions with new features – To keep things stable until LS2 How to get our users & developers to upgrade as well? – New features only in new versions (e.g. FESA 3) – Very good support for new solutions, good enough for old ones – No support for obsolete products after official end-of-life dates 520-March-2013Vito Baggiolini

6. LS1 – a time to clean up LS1 is also a moment to clean up old/unused stuff – Obsolete versions of software (source and binary) – Unused FESA classes, devices, properties – Unused settings, sequences, configurations, data – Unused NFS mounts, symbolic links, environment variables How do we know what can be cleaned-up/removed? – Usage/dependency analysis (LSA settings, Java methods) – Dynamic usage information (CCM, CMW, Logging, log files…) – But we don’t always know! If in doubt, we’ll do the clean up – If it breaks something, we’ll have to see why and fix it – If needed, we can restore removed stuff (with some effort) 620-March-2013Vito Baggiolini

7. End of LS1 – a time to test We will do Radical changes from bottom to top – New HW, new drivers, new OS, 32/64bit, new FESA, new devices, new CMW, new Java, … Unit tests in the individual development teams Function and Integration Testing in the CO testbed – “Mini-Accelerator in the lab” – Replication of different hardware and software platforms – Covers CO core systems (OS, FESA, timing, CMW, RBAC, …) – Function tests and stress tests Dry LHC-style dry runs remain essential – Driven by OP – CO and all equipment groups participate – To be inserted in the official schedule – Proposal: 2 months, 2 weeks, 2 days before beam 720-March-2013Vito Baggiolini
