module mp2d
!
! Fortran90 interface to 2d parallel PIC Fortran77 library mp2lib.f
! mp2mod.f contains multi-tasking interface procedures for
! communications with 1d partitions:
! defines module mp2d
! pmove => impmove2 moves particles to appropriate processor non-uniform
! 1d partition boundaries in 2d code.
! calls MPMOVE2, or MPXMOV2
! pmove => impdmove2 moves particles to appropriate processor
! non-uniform 1d partition boundaries in 2d code, and returns
! load imbalance.
! calls MPMOVE2, or MPXMOV2
! pmoves => impmoves2 moves particles to appropriate processor
! non-uniform 1d partition boundaries in 2d code. Optimized
! requiring that maximum number of particle passes must be
! known.
! calls MPMOVES2, or MPXMOVS2
