#2194: Memory increase during regridding
 Reporter:  wolfgang.kastaun@…   |       Type:  defect
   Status:  new                  |   Priority:  unset
Milestone:                       |  Component:  Other
  Version:  development version  |   Keywords:
 I still have the problem that my BNS runs consume increasing memory during
 inspiral, where regridding happens. It limits the runtime of typical BNS
 runs to around 1 day, then they are killed by memory exhaustion. After
 merger, with fixed grid structure, the problem goes away.
 It happens with two different codes, WhiskyThermal+McLachlan and
 WhiskyMHD+McLachlan, on all clusters I use (hydra, marconi, supermuc,
 fermi, ..), and all releases I used: Payne, Brahe, Tesla, Wheeler.
 Regridding controled using CarpetRegrid2.
