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

2. 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

3. 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.

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

5. Architecture

6. 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

7. 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.
