Mark M has an Intel 19 container working. He has run into an issue with the container size getting too large, primarily due to faulty behavior of an Intel installation process that is supposed to allow one to trim out optional compiler packages. No matter how it is configured, the installation process will install all compiler packages, which include packages we are not using in JEDI (and consume a significant amount of space). (Update: it turns out that this is a known bug in intel 19.0.5 that is expected to be addressed in a future release).

Mark M reported that the Debug build mode using Intel 19 is slow, but it did uncover a number of floating point exceptions. These appear to be related to BUMP (bump and QG bump test failures) and Mark with work with Benjamin to get these resolved.

Mark M added that he had to insert pragma statements in strategic locations of the JEDI code that shut off optimization in order to get Intel 19.0.5 to work correctly. The pragma statements were placed around regions that the compiler optimization was mistakenly changing the functionality of the code. This has to do with the model propagation for the Lorenz model so without this change, many l95 tests fail.  These cases have been reported to Intel, and hopefully Intel will be able to provide fixes soon.

Yannick asked about the status of a Navy machine of which Mark M has was to have access for debug purposes. Sarah responded that Nancy is the person to contact about this.
