Help needed to divide the remaining tasks:

https://github.com/CGNS/cgns.github.io/projects/1

The documentation goes into the source using Doxygen. This work uses the “doxygen” branch. Examples are given for cg_open and cg_version. The aliases used for repeated variable descriptions are in src/doxygen/doxygen.config. Need volunteers to help with translating the remaining APIs to Doxygen.

Converting CGNSTalk archive to Github Discussion Posts

@Scot Breitenfeld

Started converting the CGNSTalk archive to github discussion posts.

Discussion Topic

@ZJ Wang

Short discussion on past AMR CPEX (0008) and whether AMR should be revisited as a feature supported CGNS. Some groups may be already using CGNS with AMR, but not known for certain. The need for AMR support in CGNS is unknown.

@Vicky Moschou @Tobias Leicht @ZJ Wang to discuss progressing CPEX 0008.

Status update on Accepted CPEX #0045

https://cgnsorg.atlassian.net/browse/CGNS-182

@Koen Hillewaert

The branch CPEX45_high_order has not been updated since Feb 25, 2020. An update from @Koen Hillewaert on the status is needed.

@Scot Breitenfeld will email committee an update, and @Tobias Leicht may take over the discussion if needed.

NO UPDATES

Discussion Topic

@Mickael PHILIT

Proposal to have Monitoring numerical probes description to the standard. Some groups may already use CGNS to do that, but their is a need to have a shared approach.

Committee needs to review the proposal and provide feedback. @Scot Breitenfeld to send out a reminder.

Status update on Accepted CPEX #0047 Proposed Data integration Points

@Mickael PHILIT

Working on the new website before creating a new development branch to prevent duplicating efforts.

Started prototyping with python and C and will push a branch on github in the upcoming weeks.

@Tony Garratt @David Gutzwiller

Next release 4.4.0, Kanban:

General Kanban Board:

https://cgnsorg.atlassian.net/secure/RapidBoard.jspa?rapidView=3&projectKey=CGNS&selectedIssue=CGNS-190

ISSUE CARRIED OVER:

Platform proposals
Windows is under-tested. Suggest Test C and Fortran serial and parallel on Windows 10 x64 as a bare minimum

Do we test both 32bit (legacy) and 64bit API? It's a minor point, but it would a good idea to add 32bit to at least one Linux and Windows

NEW (June 2021) We need to add Intel OneAPI compilers to the list of supported compilers (note: OneAPI C/C++ compiler is very different to existing legacy one)

Bug list:

A priority of bugs to fix in next release

#1

Crucial to Ansys. Although most HPC is Linux, project set-up often was done on Windows and import/export/sharing of mesh/solution done on Windows, while most runs performed on Linux clusters

  • important to have parallel working

#4

#5

#6
