Is there a reason not to add C6 in addition to C5?

[DeniseWorthen]

hera->gaeaC5

[DeniseWorthen]

The env.gaea should probably be env.gaeac5 since this I presume gaeac6 would be different.

[apcraig]

I'm happy to merge this when ready. @rgrumbine @DeniseWorthen, just let me know when you're happy and when it's ready.

[DeniseWorthen]

@rgrumbine Gaea C5 and C6 are different machines. If the intent is to enable on Gaea, it needs to be clear which gaea.

[rgrumbine]

Agreed Denise. I'll make the update(s)

[rgrumbine]

I've made the changes and passed the quick_start suite.

[DeniseWorthen]

Are files Macros.gaea_intel and env.gaea_intel still required?

[DeniseWorthen]

This input would not be available to anyone else on Gaea. I'd suggest moving it to a world-shared space.

[rgrumbine]

Macros.gaea_intel and env.gaea_intel aren't required, but do work on both c5 and c6.

The path is actually a link to a world-shared disk. Specifying it this way, though, gives some parallelism between different platforms. For gaea, hera, and wcoss2, the path is $BOBHOME/rgdev/CICE_INPUTDATA

[DeniseWorthen]

OK, but Gaea provides "world-shared" project space for this purpose, eg /gpfs/f5/epic/world-shared/...

@rgrumbine @DeniseWorthen we are working toward a numbered release in the next few weeks, so please finish this up if you'd like to have it included. I generally think it's better to use generic, world-readable pathnames rather than those with specific usernames, for maintenance reasons.

[rgrumbine]

I agree about avoiding over-specific file paths. In this case, it is as for using Tony Craig's path on hera and other systems -- to have a shared location for the CICE input data files. At least when I started, Tony wasn't on gaea.

@DeniseWorthen I think I addressed your concerns about c5 vs. c6

[DeniseWorthen]

@rgrumbine OK, thanks. I think the "generic" gaea files (ie, w/o the c5/c6 attribute) should be removed, but I leave that to the preferences of the upstream managers to request.

I would also only note that C5 is no longer a Tier 1 platform for UWM, only C6 is now Tier 1.

I'll approve in the interests of moving the PR along though.

[rgrumbine]

thanks @DeniseWorthen
