Simulations with Float64 are generally more unstable #3094

Closed szy21 closed 2 weeks ago

szy21 commented 2 months ago

See this build for example: https://buildkite.com/clima/climaatmos-gpulongruns/builds/210#_. Most of the longrun simulations break with Float64.

Still the case after recent changes: https://buildkite.com/clima/climaatmos-gpulongruns/builds/277#_

Moist baroclinic wave and moist held suarez are stable for dt=90s with Float64 (they are stable for dt=120s with Float32): e.g. https://buildkite.com/clima/climaatmos-gpulongruns/builds/286 has moist held suarez. It might be ok.
