ROAM Control System March, 2009

In the beginning there was a plan …


ROAM Control System

• The Relocatable Ocean and Atmosphere Model (ROAM) is an operational product for predicting ocean temperatures, salinity, currents and sea-level in an user-specified domain

• The system is largely automated, with user

interaction restricted to a graphical user interface

• The ROAM software is designed to allow the user to:

Graphically specify the model domain

Control the execution of the models available

(Coordinate and manage the routine acquisition of global data from a data server)

Communication

Currently ‘Point to Point’ communication,soon Peer based communication allowing further decoupling of components and concurrency (distributed MEM’s providing specialized capability i.e. ROMS)


Data products currently utilized

Forcing data for Models:

• Ocean maps

OFAM Forecast

Near-Real-Time analysis

Behind-Real-Time analysis

• LAPS

• GASP

• SST (GHRSST)

• TC BOGUS

• WAM Regional Forecast / WAM Australian meso-scale forecast

• BRAN (hind cast)


ROAM User and Remote Control Interface



The user interface supports:

Creating and scheduling a new model run

Monitoring a model run

Aborting a model run

Deleting a model run and all its contextual information

Viewing statistics of some model runs

Managing user privileges and preferences

Graphical selection of a model domain

Provide access to the data produced by the models

Select extraction of subsets of the forcing data



The user interface can:

Run on any major platform (MS Windows, Linux, MacOSX)

Connect to the Run Control Framework from anywhere given access to the relevant network

Support multiple concurrent connection.

Support role based access control


GUI components

Run summary monitor. Shows the summary status information about currently executing runs and recently completed runs.

Detailed run monitor. Detailed run information about the currently selected run, and some limited controls.

System messages. A panel displaying information, warning and error messages about currently executing runs.

Run management. Manages the creation and editing of runs.

Run groups. Manages the creation and editing of run groups.

Preferences. Permits editing of user settings, and control of system alerts.

Administration. User and privilege management.

Alerts. Alert notification management.


ROAM User and Remote Control Interface In Detail


ROAM User and Remote Control Interface Run Summaries

Displays the status of historical, scheduled and executing runsRuns are sorted, grouped and colour-coded according to the value of the first column

Select run (highlighted in blue) to see more details in the Detailed run monitor


ROAM User and Remote Control Interface Run Details

Run Specification

• Describes the model settings and run-time parameters

• Displays the model grid as a graphical inset. More detailed view of grid appears on mouse over.



Run status

• Describes the execution status of the selected run

• Detailed execution messages are displayed in separate tabs for each model.

• All messages are time-stamped and colour-coded to indicate the importance of the message.



Run statistics

• Provides a quick visual assessment of how well the model performed and whether the statistics are within a tolerable range

• The model variables, reference heights and colour ranges are displayed

• The 10th, 50th and 90th percentiles statistics for each variable and reference height are drawn on top of a 'traffic light indicator'.

• Provide references to the designated Output.


ROAM User and Remote Control Interface In Detail

• Messages generated by the system to indicate run progress

• Transient. Stored in application cache

• Time-stamped and colour coded according to importance

Informational. Minor message.

Significant. Important message (e.g. run started, run aborted).

Warning. A potential error (e.g. forcing data is unavailable).

Error. Indicates that a fatal error occurred while trying to run the model.


Run management

The Run Editor is used to define the run parameters, model parameters and the grid definition

• All runs are stored in the RCF database

• Runs can be repeated based on previous runs

• Run templates can be created to maintain domain information

• The model combination can be selected

• Defining a run is laid out as a step by step process


Run Editor

• Run name is set to the forecast start time.

• The Atmosphere, Ocean, and Wave option toggles excluding or including the respective model.

• Forecast period can be 1, 2, 3, 5, or 7 days.


Run Editor

• Shows details of selected grid.

• Define parameters: origin, resolution, aspect ratio, number of cells.

• Visual feedback as to whether the run estimate is within the tolerable range.

• Depending on which group of models are selected, tabs show the dependent grids.


Graphical Grid Editor

• Ocean grids is defined inside the atmospheric grid • Grid can be extended a long a boundary and shifted using the grid handles.

Toolbar buttons allow for zoom in, zoom out, rapid zoom out, pan and print.


Graphical Grid Editor

• The Coarse runtime estimate gives an indication of how long the run will take, based on previous historical runs.

• Refined runtime estimate uses the model specifications to compute a more accurate runtime.

• Clicking the ‘Get estimate’ button gives a graphical representation of the refined runtime estimate in hours.

Depth and height contours can be modified (in intervals of 100m) by using slider or up/down keys.


Run scheduling options

• Options for setting execution start time

None

Immediate

Start after completion of a specific run

User specified time

• Option to repeat a run every 12 or 24 hours

• Run priority – low, medium, high


Run Summary

The summary panel displays the details for all submitted models. This step is not required for submitting runs.


ROAM Overview

• The Relocatable Ocean and Atmosphere Model (ROAM) is an operational product for predicting atmospheric an oceanic properties in an user-specified domain

• The system is largely automated, with user

interaction restricted to a graphical user interface

• The ROAM software is designed to allow the user to:

Graphically specify the model domain

Control the execution of the models available

Retrieve the output of successful runs automatically through dedicated upload Break


Where to in the short term…

The ROAM team is currently;

• incorporating more models (i.e NearCom)

• incorporating more data streams (i.e.Global SST)

• enable expert users to customize the combination of forcing

• enable expert users to customize general parameters of a specific model

• enable expert users to create ensembles of runs (i.e. for parameter estimation)


… in the mid term

With establishing IMOS and EMII,

it is expected that a variety of data will be made available via OpenDAP server also providing access to meta data, given the currently being implemented standards;

ROAM could be able to discover the latest published data and utilize it to force models,

Create ensembles of comparative model runs over the same domain using distributed data streams,

and much more...

Later this year,

ROAM will be moving to a peer driven and capability based communication model, as a result ROAM becomes truly distributed!
