CGNS version number specification

Scot Breitenfeld Vangelis Skaperdas

•  Beta-cae will summarize the issue and the proposed solution to the version issue
•  Koen Hillewaertwill send out the Beta-cae document to the entire committee for discussion, and to follow-up with a vote as to whether to increase the CGNS version to 4.0, or to continue with the 3.x series and to just provide a graceful exit fix. The issue will also be raised on CGNStalk after the committee discussion.
•  Koen Hillewaert at the next meeting will propose removing the promise of forward compatibility from the documentation and will take a vote on the issue

Removal of cgio_read_data, cgio_read_all_data, cgio_read_block APIs, or restrict to ADF format only.

Scot Breitenfeld ​

•  Committee voted to remove the APIs, Scot Breitenfeld will remove the APIs in the next release, and update the documentation listing the alternative APIs which should be used in their place.

Platform support questions and proposals

Drop SunOS - do we know any users using this platform?

Drop Windows 7 and 8

Why are we still testing AIX - do we have any known users on this platform?

Windows is under-tested - Proposal-> 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

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

#2

#3

- important to have parallel working

#4

#5

#6

​Conflicting bugs - are we supporting configure or not? Very confusing to end-users

Overall comments from Ansys

Configure much easier to use than cmake. Ansys would prefer we drop cmake and move back to configure - but see above - are we moving to cmake only or not??

Make LFS the default - 2Gb is tiny by today's standards. Any reasons not to make LFS the default (performance issues for instance?) and introduce LFS=off or SFS option for backward compatibility

•  Tony Garratt will add the LFS option as a Jira issue.

Add large file test cases >4Gb serial and parallel both platforms

Overall needs of Ansys - these items and bug fixes important to use, not any of the new enhancements right now.

Overall comments from NUMECA

I generally agree with the comments from ANSYS / Tony Garrett. I will second a few points based on NUMECA's needs:

Highest priority bugs:

We have disabled parallel CGNS in our release packages until CGNS 176 and CGNS 109 are fixed, it became a problem for our support engineers.

I agree with the comments on configure vs CMAKE. Our internal library maintenance system is built on configure, and it would be nice to maintain support if possible.

•  David GutzwillerTony Garratt will update the issues mentioned to be scheduled for the next release in JIRA.

• There is no current plan to drop Autotools support.

high-level editing tools for the documentation page

Marc Poinot Christopher Rumsey ​

Raw html is not an ideal format to maintain documentation, the latex version seemed easier. It was mentioned to maybe go back to using latex, but the latex version is now out of date compared to the html version. Some committee members were uncertain whether the latex format was the right way to go when compared to other documentation methods (Markdown, Readthedocs, etc…). Either way, it will involve some effort to move from the html versions.

•  Marc Poinot will look into latex state of documentation and will look into alternatives to raw HTML.
