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. We need volunteers to help with translating the remaining APIs to Doxygen.

• A link to the new website is provided on the main cgns web page: https://cgns.github.io/cgns-modern.github.io/index.html

• All the MLL APIs have Doxygen entries, the cgio APIs need to be done next.

• An automatic generation of the website through GitHub action is done.

Still in progress.

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.

No new updates.

Status update on Accepted CPEX #0045

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 get an update on the status.

Discussion Topic

Mickael PHILIT

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

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

No new updates.

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. (The “C” branch is a slow work in progress)

No new updates.

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

Scot Breitenfeld is working on updating the Multi-dataset APIs in CGNS to use the new array-based API and is testing CGNS with the new HDF5 subfiling feature.
