Agreed should pitch it at novice researcher\/student with no links to existing community<\/li>\n<li>Should start by using ourselves as the audience, define them for our use and expand from there<\/li>\n<li>First test case should be the ACCESS-OM-025 (Quarter degree MOM+CICE+OASIS-mct)<\/li>\n<li>CICE is currently housed on CWS github repo<\/li>\n<li>Agreed we need consolidated location for model code. Nic suggested a git repo pulling in model components using submodules. This makes it clean to install and allows for control of versions via explicit commits or tags<\/li>\n<li>COSIMA name is taken on github, so agreed to use existing OceansAus group<\/li>\n<li>Minimal technical detail on website, instead point to github repo<\/li>\n<\/ul>\n<h3>Input data<\/h3>\n<ul>\n<li>Data store for model input files &#8211; decided to use the ua8 Ramadda location which is currently used for MOM5 test cases<\/li>\n<li>Need data versioning<\/li>\n<\/ul>\n<h3>Benchmarking<\/h3>\n<ul>\n<li>Need example outputs, and timings. Direct users to run the model and compare their outputs and timings to those supplied to verify model integrity and performance<\/li>\n<li>Need continuous integration to test against these outputs. Nic currently running a dozen test cases on a Jenkins server for MOM5. Can add these tests too.<\/li>\n<li>Essential to allow upgrading of model components with confidence they have not affected model integrity and performance.<\/li>\n<\/ul>\n<h3>Tools\/Utilities<\/h3>\n<ul>\n<li>Desirable to also have related tools and utilities on the OceansAus github site<\/li>\n<li>Concerns that the site collect crufty tools, so make some standard for what constitutes a repo: utility, support and documentation?<\/li>\n<\/ul>\n<h3>Model Support<\/h3>\n<ul>\n<li>How do we support these models? Decided the existing MOM mailing list would suffice for general user questions. Stephen Griffies has been interested in supporting a MOM-CICE configuration. Also github issues can be used for specific code issues.<\/li>\n<\/ul>\n<h3>Mission Statement<\/h3>\n<ul>\n<li>Desirable to have a general mission statement about what the aims of the TWG<\/li>\n<li>Any additional invitees? Perhaps Mirko from the BoM? Open invitation to anyone who wants to attend and contribute<\/li>\n<\/ul>\n<h3>General technical discussion<\/h3>\n<ul>\n<li>Aidan described progress with improving vertical grid in MOM-SIS 0.1 deg config<\/li>\n<li>Justin working on making his real time flythrough data-vis software available on raijin, Maybe use Russ\u2019 BRAN2015 reanalysis dataset with recent El Nino<\/li>\n<li>Matt is adding sea-ice to the OFAM grid and tuning parameters to reduce SST biases. Turning off neutral physics helped.<\/li>\n<li>Ben Evans wants a WOMBAT test case, perhaps use the 0.25 deg runs Matt did with Paul Spence?<\/li>\n<li>Marshall has updated FMS and he and Nic have used Jenkins testing to find and fix bugs. Close to being added to master branch of MOM5<\/li>\n<\/ul>\n<h3>COSIMA website<\/h3>\n<ul>\n<li>A lot of enthusiasm for contributing blog posts to website from technical perspective.<\/li>\n<\/ul>\n<h3>Actions<\/h3>\n<ul>\n<li>Aidan to add Nic to OceansAus group<\/li>\n<li>Nic to create initial ACCESS-OM-025 repo with submodules for MOM5\/CICE\/OASIS-mct<\/li>\n<li>Justin volunteered to test out initial model config as \u201cnew user&#8221;<\/li>\n<li>Marshall to write draft mission statement<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Minutes Date: 2nd August 2016 Attendees: Marshall Ward (NCI, Chair) Aidan Heerdegen (ARCCSS) Nic Hannah (ARCCSS\/Breakaway Labs) Justin Freeman (BoM) Russ Fiedler and Matt Chamberlain (CSIRO Hobart) Agreed to have monthly videoconference meetings.
