This effort will include:

  • Standard MG method
  • Standard AMG method (P2)
  • MGPCG
  • AMGPCG (P2)

For AMGPCG, libWetHair seems to have a readable implementation: https://github.com/nepluno/libWetHair

Everything except AMGPCG is completed. Leaving that as another bulk of work and closing this ticket.
