Re: [stem-dev] Minutes from todays community call Weds Mar 11, 2021

Just in case there are those who are building the STEM development environment as in
As mentioned in the minutes of the last community meeting, STEM can now run on Java 11. Recommended package to use is the Eclipse Modeling Tools (has all the needed prerequisites).
Slight problem with the latest 2021-03 R release of the IDE, the Eclipse Java packages seem to have undergone some changes and exhibit some inconsistencies with the STEM source code.
Jamie confirmed these are most likely warnings and not errors per se.
After pulling the source code from the repository and applying the correct target environment, click on the newly applied target environment item in Preferences -> Plug-in Development -> Target Platform (there's an error indicator on it), and click "Edit..."
Select the error item (there is a sub-item that says "Unable to locate installable unit") and click on "Update"
After the packages are updated, building the STEM development environment proceeds as normal.
BTW, I'm using Linux (RHEL 8.3)

        Updated required plugins
        Verified maven build (build is now working again)

3. Apache Simplex algorithm. Rjel will investigate

4. Nelder-Mead progress logger (possible performance issue)
5. STEM on Cloud (STEM 5.0) updates
6. New Bugs:
571476 Unable to run from 'development' environment on MacOS BigSur  (FIXED)
571668 bundle required JRE with STEM application (FIXED)

7. Items from Participants.
Taras: Is there an R library or other external for orchestrating large scale STEM simulations on server?
This can be/has been done but the exact implementation depends on the specific use case. The STEM5 plan that Ahmad is workin on would simplify this type of orchestration.

8. Next Call (confirming the Apr. 15)
