.HP
.SH "MPP FUNCTION DESCRIPTIONS"
.LP
Additional functions for use on SGI/Cray MPP machines (_CRAYMPP).
These are used to set and inquire which PE is the base for MPP
for a particular netCDF. These are only relevant when
using the SGI/Cray ``global''
Flexible File I/O layer and desire to have
only a subset of PEs to open the specific netCDF file.
For technical reasons, these functions are available on all platforms.
On a platform other than SGI/Cray MPP, it is as if
only processor available were processor 0.
These functions were used on archaic SGI/Cray MPP machines. These
functions are retained for backward compatibility; the PE arguments
must all be set to zero.
.LP
To use this feature, you need to specify a communicator group and call
CODE(glio_group_mpi(\|)) or CODE(glio_group_shmem(\|)) prior to the netCDF
FREF(open) and FREF(create) calls.
.HP
FDECL(_create_mp, (IPATH(), ICMODE(), IINITSIZE(), IPE(), OCHUNKSIZE(), ONCID()))
.sp
Like FREF(_create) but allows the base PE to be set.
Like FREF(_create).
.sp
The argument ARG(pe) sets the base PE at creation time. In the MPP
environment, FREF(_create) and FREF(create) set the base PE to processor
zero by default.
The argument ARG(pe) must be zero.
.HP
FDECL(_open_mp, (IPATH(), IMODE(), IPE(), OCHUNKSIZE(), ONCID()))
.sp
Like FREF(_open) but allows the base PE to be set.
The argument ARG(pe) sets the base PE at creation time. In the MPP
environment, FREF(_open) and FREF(open) set the base PE to processor
zero by default.
Like FREF(_open).
The argument ARG(pe) must be zero.
.HP
FDECL(inq_base_pe, (INCID(), OPE()))
.sp
Inquires of the netCDF dataset which PE is being used as the base for MPP use.
This is safe to use at any time.
Always returns pe of zero.
.HP
FDECL(set_base_pe, (INCID(), IPE()))
.sp
Resets the base PE for the netCDF dataset.
Only perform this operation when the affected communicator group
synchronizes before and after the call.
This operation is very risky and should only be contemplated
under only the most extreme cases.
This function does nothing.
