! Now for the choices:
|
|
! IPK = integer kind for "local" indices and sizes.
|
|
! Can be 4 or 8 bytes.
|
|
! LPK = integer kind for "global" indices and sizes.
|
|
! Can be 4 or 8 bytes.
|
|
! Size must be >= size of IPK
|
|
!
|
|
! Additional rules:
|
|
! 1. MPI related stuff is always MPK
|
|
! 2. ctxt,IAM,NP: should we have two versions of everything,
|
|
! one with MPK the other with EPK?
|
|
! 3. INFO, ERR_ACT, IERR etc are always IPK
|
|
! 4. For the array version of things, where it makes sense
|
|
! e.g. realloc, snd/receive, define as MPK,EPK and the
|
|
! compiler will later pick up the correct version according
|
|
! to what IPK/LPK are mapped onto.
