@danielabdi-noaa For the Hera GNU fundamental test suite - I'm finding that both grid_RRFS_CONUScompact_13km_ics_FV3GFS_lbcs_FV3GFS_suite_GFS_v16 and grid_RRFS_AK_13km_ics_FV3GFS_lbcs_FV3GFS_suite_GFS_v16 are taking over two and half hours two complete.

Should these two tests be included in the fundamental tests? I feel that the fundamental tests should complete within two hours and not be resource intensive. These two tests both take longer to complete and are fairly resource intensive as well.

@MichaelLueken We can definately remove them. I think for me they took 30 mins but i may have used the intel binary

The community_ensemble_2mems has 2 members and 2 cycles so it is most likely 4x more compute intensive than others. So it doesn't hurt to remove a couple, so I will remove them.
