Richard Carr, ESAC, January 2015 Solar Orbiter SOWG 6 SEGU SOC Engineering Guidelines For External Users Richard Carr, ESAC, January 2015

Instrument Teams Low Latency Pipelines Purpose “engineering procedures to be followed by external users (e.g. Instrument Teams) to develop, validate and integrate data and SW in the SOC” (SOC Document Tree) Thus Instrument Teams Low Latency Pipelines

Approach Virtual Machine images OVF Standard SEGU defines interfaces for: Data input to each VM Data output from VM VM delivery to SOC Advantages of Virtual Machines Lifetime of platform. Greatly simplifies deployment. At SOC. But also multiple copies in development/testing. Symmetrical mechanism across instruments. Cloneable, notably for diagnostics.

Approach VMs Run At instrument sites (development/testing/operations) At SOC Acceptance Testing environment Production (Operations) Self-Configuration at Boot Properties file supplied externally.

Architecture

Status Various versions circulated in LL Engineering group. Discussed in Telecons (3 since SOWG 5). Version 0.7 circulated last week. Consensus on approach. VM delivery to ESAC successful (automation still pending) Auto-configuration successfully prototyped. 0.7 -> 1.0 after this meeting

LL Pipeline Engineering Splinter LL Pipeline VM Configuration for different environments. ROB & ESAC have prototypes. Investigations of Application level SW architecture and tools. Also licencing. Feedback on SEGU. Test data availability (from DDS). How this fits schedule. Tendency to follow a couple of pioneer instruments. More telecons to follow. Also Forum.
