- The goals of the early integration pathfinder exercises are - - PowerPoint PPT Presentation

• The goals of the early integration pathfinder exercises are
• Overall goal: Ensure that when different instruments, in particular AuxTel, ComCam and

Full Camera are installed on the summit TCS/OCS/DM/CCS/DAQ all work as expected

• Promote interaction between all principal subsystem control software
• Perform interface testing
• Clarify and solidify those interfaces
• Identify areas of deficiency and address those issues
• Exercises build on the work of previous ones
• Test early, test often!
• A number of pathfinder exercises have been performed over the past 2

years, with more upcoming

• Valuable lessons have been learned in the process, and will likely continue to be learned in

the future

• 1-Visit Night Control Only (Oct 9-10, 2017 @ NCSA)
• DM Header Service Capability Test (Dec 12, 2017 @ Tucson)
• DAQ Hardware to Support Wavefront/Guider Testing (Feb 13-14, 2018 @

Tucson)

• DAQ to DM Files (Mar 1, 2018 @ Tucson)
• 1-Visit Night with Images AuxTel (April 3-4, 2018 @ NCSA)
• Manual Control of Multiple Physical Devices on AuxTel (June 7, 2018 @

Tucson)

• FITS File Assembly at NCSA (June 14, 2018 @ NCSA)
• ACCS MCM/OCS Bridge for Spectrograph Integration Test (July 17-19,

2018 @ Tucson)

• Primary goal is to test software interoperability, this is aided and in some

cases requires that we use the same/similar IT setup as expected on summit

• A number of areas of overlap have already been identified and are being worked on
• Need for common OS
• Centos7 has been adopted as the standard baseline operating system, and is

being used for all pathfinder activities.

• Need for common installation methodology
• Puppet has been selected as the software installation tool,
• Goal is to use puppet for all software installs during pathfinder exercises
• Need for common identity management and group definitions
• Work is ongoing in partnership with NCSA to get IDM installed in Tucson using

puppet

• Need for common documentation and issue tracking tools
• We are already using JIRA, Confluence and Magic Draw, others to follow

• Additional technologies we expect to test in future
• Configuration management
• Ensuring we know which versions of software from different subsystems will

interoperate

• Simulation environments for testing software prior to installation on summit
• Automatic testing and reporting tools
• Network infrastructure (IP address, virtual networks, summit/base inter-operability)
• Shared file systems
• Remote access technologies and cyber security
• VPN, ssh, VNC (like) technologies
• Access control (perhaps basd on location)
• PTP time standard distribution
