Purpose and Goals of the Meeting
The Technology Review is one of four goals of our Cycle-1 plan for Lasair-LSST development. So far, we have a mature working prototype (Lasair-ZTF); clear science requirements; a high-level technology-free component and flow design; and a long term development plan, broken into six monthly cycles. The next step is to take some key baseline technology decisions, so that we can undertake detailed technical design and development. This meeting is intended therefore as a relatively lightweight, semi-formal preliminary Technical Design Review. The goals are to:
Identify the key technology decisions to make
Review the results of related tests and experiments
Conclude as many key technology choices as possible
Clarify remaining technology choices to be made
Set further tests in order to reach conclusions
Outline a technical design
Place/Date
ROE rooftop gallery. (See information on Visiting IfA)
The meeting is roughly one day spread over two.
Tues March 17th 11:00 -6:00pm
Wed March 18th 9:00am - 1:00pm
An informal pub dinner is planned for Tuesday evening.
Session-1: Introduction and Context
For general context, see papers O1-O6 below
Introduction and goals of meeting (Andy)
Context: Rubin observatory, LSST and LSST:UK (Stephen)
Lasair today: what it does, how it works (Roy)[see paper O5]
Sherlock: what it does, how it works (Dave)
Lasair planning process (Andy)[see paper O2]
Lunch break
Session-2 Discussion of Key Technology Areas – after lunch
Technology overview: what needs to be decided? (Roy) [see paper O1]
Key Area-1 : Receiving and Processing the Data Flow
initial summary …LSST public and private; galaxies, stars and rocks (Stephen) (paper)
Lasair ingestion with SSD (Ken) (paper)
Handling light curves (Roy) (paper)
Parallel ingestion and workflow (Roy) (paper)
Streaming queries (Gareth)
Making a super Sherlock (Ken) (paper)
Key Area-2: Databases, Storage, Internal Structure
initial summary ….MySQL vs Cassandra, query languages (Ken) (paper)
Blob storage requirements and technology (Gareth) (summary)
Key Area-3: User services - querying, extraction, analysis
initial summary …Light curve classification and features (Michael) (paper)
Lasair and the LSST Science Platform (Stelios)
As we step through the presentations on the Key Areas, we should decide and record the key technology decisions needed, but will actually decide them the next day.
Tues evening: Pub dinner for those who wish
Session-3 Key Technologies review
Recap of Day-1 discussions
Debate the key technology decisions
Conclude as many as possible
coffee break
Session-4 Conclusions
Review remaining technology decisions
Set further evaluations needed to conclude these
Outline Technology Design
Supplied Paperwork
Some of the material will be verbal/powerpoint, but we will upload PDF versions here as they become available. Pre-supplied written papers will be as above:
Overview documents
(O1) High-level diagram: detailed version and simplified version
(O2) Lasair-PhaseB plan
(O3) LSST:UK Phase B proposal
(O4) LUSC-A-02 LSST approach to alerts and variables
(O5) LUSC-A-08 The Lasair Broker (i.e. Phase A prototype)
(O6) LUSC-A-09 Initial science requirements for variable science
These are pre-existing written documents and will be uploaded here in advance of meeting.
These are being developed on the Lasair Technology Papers wiki page, but should be turned into PDFs to be uploaded here in advance of meeting.
