Please do standalone Icepack testing including regression testing.

[dabail10]

I did the Icepack regression testing with intel, pgi, and gnu on cheyenne. Everything is bfb.

[dabail10]

I agree. I should probably add tests for both.

[apcraig]

Sounds good. Maybe we can merge the Icepack PR today and the CICE PR in the next day or two then I can start testing for the release. Thanks!

[apcraig]

How about if we call the salt test "saltprog" instead of just "salt"? Does the new test pass?

[dabail10]

If we are doing a longer name I would prefer saltflux.

[dabail10]

The test passes in CICE with the updated Icepack submodule.

[apcraig]

saltflux is OK too. Or saltfluxprog. Can you also do a quick run with standalone Icepack for the new test. Lets just make sure it runs and passes. Then we can merge. Thanks!

[dabail10]

Did quick_suite on intel.

./icepack.setup --suite quick_suite --mach cheyenne --env intel --testid saltflux4 -s saltflux

10 measured results of 10 total results 10 of 10 tests PASSED 0 of 10 tests PENDING 0 of 10 tests MISSING data 0 of 10 tests FAILED

[apcraig]

The new test is in the base_suite.

[apcraig]

OK, I see you ran quick_suite with -s saltflux. I guess that's OK too.

[apcraig]

You need to add set_nml.saltflux to your push.

[dabail10]

Whoops. Should be there now.
