SEQ fails on GPUs
SEQ strategy is failing on GPUs as of https://github.com/GEOS-DEV/GEOS/commit/da6e83fc4f0f43a803b3300a3ec955ae0f404662

Hey, @jhuang2601 what h/w are you running these on ?
for SEAM: looks like there is some issue with those params:
amgThreshold="0.6"
amgAggressiveCoarseningLevels="1"
when i removed them - it runs just fine, while before it was stuck at first mechanical solve.

I can confirm hanging at random places (re-run multiple time and it will hang at different linear solve)
