\? Description. This is a FORTRAN 77-callable version of the HPF subroutine
HPF_SUBGRID_INFO.
\? Arguments.
IERR1 is a scalar integer of default kind. It is an INTENT (OUT) argument. Its return value is zero if LB, UB, and STRIDE were determined successfully and nonzero otherwise.
IERR2 is a scalar integer of default kind. It is an INTENT (OUT) argument. Its return value is zero if LB_EMBED and UB_EMBED were determined successfully and nonzero otherwise.
LB, UB, STRIDE, LB_EMBED, UB_EMBED, AXIS_MAP
are ``inquiry results'' of default integer type.
They are the lower and upper bounds and strides
of the array sections describing the local data (in terms of
global indices), the lower and upper bounds of the embedding
arrays (again, in terms of global indices), and the axes of
the embedding arrays to which the axes of ARRAY are
mapped.
