50.9 ESMF_CONTEXT
DESCRIPTION:
Indicates the type of VM context in which a Component will be executing its
standard methods.
The type of this flag is:
type(ESMF_Context_Flag)
The valid values are:
- ESMF_CONTEXT_OWN_VM
- The component is running in its own, separate VM context. Resources
are inherited from the parent but can be arranged to fit the
component's requirements.
- ESMF_CONTEXT_PARENT_VM
- The component uses the parent's VM for resource management. Compared
to components that use their own VM context components that run in the
parent's VM context are more light-weight with respect to the overhead
of calling into their initialize, run and finalize methods.
Furthermore, VM-specific properties remain unchanged when going from
the parent component to the child component. These properties include
the MPI communicator, the number of PETs, the PET labeling,
communication attributes, threading-level.
50.10 ESMF_COORDSYS
DESCRIPTION:
A set of values which indicates in which system the coordinates in a class (e.g. Grid) are. This type is useful both
to indicate to other users the type of the coordinates, but also to control how the coordinates are interpreted in ESMF
methods which depend on the coordinates (e.g. regridding methods like ESMF_FieldRegridStore()).
The type of this flag is:
type(ESMF_CoordSys_Flag)
The valid values are:
- ESMF_COORDSYS_CART
- Cartesian coordinate system. In this system, the cartesian coordinates are mapped to the Grid coordinate dimensions in the following order: x,y,z. (E.g. using coordDim=2 in ESMF_GridGetCoord() references the y dimension)
- ESMF_COORDSYS_SPH_DEG
- Spherical coordinates in degrees. In this system, the spherical coordinates are mapped to the Grid coordinate dimensions in the following order: longitude, latitude, radius. (E.g. using coordDim=2 in ESMF_GridGetCoord() references the latitude dimension) Note, however, that ESMF_FieldRegridStore() currently just supports longitude and latitude (i.e. with this system, only Grids of dimension 2 are supported in the regridding).
- ESMF_COORDSYS_SPH_RAD
- Spherical coordinates in radians. In this system, the spherical coordinates are mapped to the Grid coordinate dimensions in the following order: longitude, latitude, radius. (E.g. using coordDim=2 in ESMF_GridGetCoord() references the latitude dimension) Note, however, that ESMF_FieldRegridStore() currently just supports longitude and latitude (i.e. with this system, only Grids of dimension 2 are supported in the regridding).

50.32 ESMF_LINETYPE
DESCRIPTION:
This argument allows the user to select the path of the line which connects two points on the surface of a sphere.
This in turn controls the path along which distances are calculated and the shape of the edges that make up a cell.
The type of this flag is:
type(ESMF_LineType_Flag)
The valid values are:

When calculating regrid weights, this line type is currently the default for the following regrid methods: ESMF_REGRIDMETHOD_BILINEAR,
ESMF_REGRIDMETHOD_PATCH, ESMF_REGRIDMETHOD_NEAREST_STOD, and ESMF_REGRIDMETHOD_NEAREST_DTOS.
- ESMF_LINETYPE_GREAT_CIRCLE

50.37 ESMF_MESHLOC
DESCRIPTION:
Used to indicate a specific part of a Mesh. This is commonly used to specify the part of the Mesh to
create a Field on.
The type of this flag is:
type(ESMF_MeshLoc)
The valid values are:
- ESMF_MESHLOC_NODE
- The nodes (also known as corners or vertices) of a Mesh.
- ESMF_MESHLOC_ELEMENT
- The elements (also known as cells) of a Mesh.
50.38 ESMF_MESHOP

- ESMF_METHOD_INITIALIZE
- Initialize method.
- ESMF_METHOD_READRESTART

- ESMF_METHOD_RUN
- Run method.
- ESMF_METHOD_WRITERESTART

DESCRIPTION:
When doing conservative regridding (e.g. ESMF_REGRIDMETHOD_CONSERVE), this option allows the user to select the type of normalization used when producing the weights.
type(ESMF_NormType_Flag)
The valid values are:
- ESMF_NORMTYPE_DSTAREA
- Destination area normalization. Here the weights are calculated by dividing the area of overlap of the source and
destination cells by the area of the entire destination cell. In other words, the weight is the fraction of the
entire destination cell which overlaps with the given source cell.
- ESMF_NORMTYPE_FRACAREA
- Fraction area normalization. Here in addition to the weight calculation done for destination area normalization
(ESMF_NORMTYPE_DSTAREA) the weights are also divided by the fraction that the destination cell overlaps with
the entire source grid. In other words, the weight is the fraction of just the part of the destination cell that
overlaps with the entire source mesh.
This flag is documented in section 47.2.1.
This flag is documented in section 30.2.5.
50.43 ESMF_POLEMETHOD
DESCRIPTION:
When interpolating between two Grids which have been mapped to a sphere these can be used to specify the type of artificial pole to create on the source Grid during interpolation. Creating the pole allows destination points above the top row or below the bottom row of the source Grid to still be mapped.
The type of this flag is:
type(ESMF_PoleMethod_Flag)
The valid values are:
- ESMF_POLEMETHOD_NONE
- No pole. Destination points which lie above the top or below the bottom row of the source Grid won't be mapped.
- ESMF_POLEMETHOD_ALLAVG
- Construct an artificial pole placed in the center of the top (or bottom) row of nodes, but projected onto the sphere formed by the rest of the grid. The value at this pole is the average of all the source values surrounding the pole.
- ESMF_POLEMETHOD_NPNTAVG
- Construct an artificial pole placed in the center of the top (or bottom) row of nodes, but projected onto the sphere formed by the rest of the grid. The value at this pole is the average of the N source nodes next to the pole and surrounding the destination point (i.e. the value may differ for each destination point). Here N is set by using the regridPoleNPnts parameter and ranges from 1 to the number of nodes around the pole. This option is useful for interpolating values which may be zeroed out by averaging around the entire pole (e.g. vector components).
- ESMF_POLEMETHOD_TEETH
- No new pole point is constructed, instead the holes at the poles are filled by constructing triangles across the top and bottom row of the source Grid. This can be useful because no averaging occurs, however, because the top and bottom of the sphere are now flat, for a big enough mismatch between the size of the destination and source pole holes, some destination points may still not be able to be mapped to the source Grid.
50.44 ESMF_REDUCE
DESCRIPTION:
Indicates reduce operation
The type of this flag is:
type(ESMF_Reduce_Flag)
The valid values are:
- ESMF_REDUCE_SUM
- Use arithmetic sum to add all data elements.
- ESMF_REDUCE_MIN
- Determine the minimum of all data elements.
- ESMF_REDUCE_MAX
- Determine the maximum of all data elements.
50.45 ESMF_REGION
DESCRIPTION:
Specifies various regions in the data layout of an Array or Field object.
The type of this flag is:
type(ESMF_Region_Flag)
The valid values are:
- ESMF_REGION_TOTAL
- Total allocated memory.
- ESMF_REGION_SELECT
- Region of operation-specific elements.
- ESMF_REGION_EMPTY
- The empty region contains no elements.
50.46 ESMF_REGRIDMETHOD
DESCRIPTION:
Specify which interpolation method to use during regridding. For a more detailed discussion of these methods, as well as ESMF regridding in general, see Section 23.2.
The type of this flag is:
type(ESMF_RegridMethod_Flag)
The valid values are:
- ESMF_REGRIDMETHOD_BILINEAR
- Bilinear interpolation. Destination value is a linear combination of the source values in the cell which contains the destination point. The weights for the linear combination are based on the distance of destination point from each source value.
- ESMF_REGRIDMETHOD_PATCH
- Higher-order patch recovery interpolation. Destination value is a weighted average of 2D polynomial patches constructed from cells surrounding the source cell which contains the destination point. This method typically results in better approximations to values and derivatives than bilinear. However, because of its larger stencil, it also results in a much larger interpolation matrix (and thus routeHandle) than the bilinear.
- ESMF_REGRIDMETHOD_NEAREST_STOD
- In this version of nearest neighbor interpolation each destination point is mapped to the closest source point. A given source point may go to multiple destination points, but no destination point will receive input from more than one source point.
- ESMF_REGRIDMETHOD_NEAREST_DTOS
- In this version of nearest neighbor interpolation each source point is mapped to the closest destination point. A given destination point may receive input from multiple source points, but no source point will go to more than one destination point.
- ESMF_REGRIDMETHOD_CONSERVE
- First order conservative interpolation. Value of a destination cell is the weighted sum of the values of the source cells that it overlaps. The weights are determined by the amount the source cell overlaps the destination cell. Will typically give less accurate approximations to values than the other interpolation methods, however, will do a much better job preserving the integral of the value between the source and destination. Needs corner coordinate values to be provided in the Grid. Currently only works for Fields created on the Grid center stagger (or the Mesh element location).
50.47 ESMF_ROUTESYNC
DESCRIPTION:
Switch between blocking and non-blocking execution of RouteHandle based
communication calls. Every RouteHandle based communication method contains
an optional argument routesyncflag that is of type ESMF_RouteSync_Flag.
The type of this flag is:
type(ESMF_RouteSync_Flag)
The valid values are:
- ESMF_ROUTESYNC_BLOCKING
- Execute a precomputed communication pattern in blocking mode. This
mode guarantees that when the method returns all PET-local data
transfers, both in-bound and out-bound, have finished.
- ESMF_ROUTESYNC_NBSTART
- Start executing a precomputed communication pattern in non-blocking
mode. When a method returns from being called in this mode, it
guarantees that all PET-local out-bound data has been transferred.
It is now safe for the user to overwrite out-bound data elements.
No guarantees are made for in-bound data elements at this stage. It is
unsafe to access these elements until a call in
ESMF_ROUTESYNC_NBTESTFINISH mode has been issued and has returned
with finishedflag equal to .true., or a call in
ESMF_ROUTESYNC_NBWAITFINISH mode has been issued and has returned.
- ESMF_ROUTESYNC_NBTESTFINISH
- Test whether the transfer of data of a precomputed communication
pattern, started with ESMF_ROUTESYNC_NBSTART, has completed.
Finish up as much as possible and set the finishedflag to
.true. if all data operations have completed, or
.false. if there are still outstanding transfers. Only after
a finishedflag equal to .true. has been returned is it
safe to access any of the in-bound data elements.
- ESMF_ROUTESYNC_NBWAITFINISH
- Wait (i.e. block) until the transfer of data of a precomputed
communication pattern, started with ESMF_ROUTESYNC_NBSTART, has
completed. Finish up all data operations and set the returned
finishedflag to .true.. It is safe to access any of the
in-bound data elements once the call has returned.
- ESMF_ROUTESYNC_CANCEL
- Cancel outstanding transfers for a precomputed communication pattern.
This flag is documented in section 47.2.2.
This flag is documented in section 30.2.6.
50.50 ESMF_STARTREGION
DESCRIPTION:
Specifies the start of the effective halo region of an Array or Field object.
The type of this flag is:
type(ESMF_StartRegion_Flag)
The valid values are:
- ESMF_STARTREGION_EXCLUSIVE
- Region of elements that are exclusively owned by the local DE.
- ESMF_STARTREGION_COMPUTATIONAL
- User defined region, greater or equal to the exclusive region.
This flag is documented in section 20.2.1.
This flag is documented in section 20.2.2.
50.53 ESMF_SYNC
DESCRIPTION:
Indicates method blocking behavior and PET synchronization for VM communication
methods, as well as for standard Component methods, such as Initialize(), Run()
and Finalize().
For VM communication calls the ESMF_SYNC_BLOCKING and ESMF_SYNC_NONBLOCKING
modes provide behavior that is practically identical to the blocking and
non-blocking communication calls familiar from MPI.
The details of how the blocking mode setting affects Component methods are
more complex. This is a consequence of the fact that ESMF Components can be
executed in threaded or non-threaded mode. However, in the default,
non-threaded case, where an ESMF application runs as a pure MPI or mpiuni
program, most of the complexity is removed.
See the VM item in 6.5 for an
explanation of the PET and VAS concepts used in the following
descriptions.
The type of this flag is:
type(ESMF_Sync_Flag)
The valid values are:
- ESMF_SYNC_BLOCKING
- Communication calls: The called method will block until all
(PET-)local operations are complete. After the return of a blocking
communication method it is safe to modify or use all participating
local data.
Component calls: The called method will block until all PETs of
the VM have completed the operation.
For a non-threaded, pure MPI
component the behavior is identical to calling a barrier before
returning from the method. Generally this kind of rigid
synchronization is not the desirable mode of operation for an MPI
application, but may be useful for application debugging.
In the opposite case, where all PETs of the component are running as
threads in shared memory, i.e. in a single VAS, strict synchronization
of all PETs is required to prevent race conditions.
- ESMF_SYNC_VASBLOCKING
- Communication calls: Not available for communication calls.
Component calls: The called method will block each PET until
all operations in the PET-local VAS have completed.
This mode is a combination of ESMF_SYNC_BLOCKING and
ESMF_SYNC_NONBLOCKING modes. It provides a default setting
that leads to the typically desirable behavior for pure MPI
components as well as those that share address spaces between PETs.
For a non-threaded, pure MPI component each PET returns
independent of the other PETs. This is generally the expected
behavior in the pure MPI case where calling into a component method is
practically identical to a subroutine call without extra
synchronization between the processes.
In the case where some PETs of the component are running as
threads in shared memory ESMF_SYNC_VASBLOCKING becomes identical
to ESMF_SYNC_BLOCKING within thread groups, to prevent race
conditions, while there is no synchronization between the thread
groups.
- ESMF_SYNC_NONBLOCKING
- Communication calls: The called method will not block but
returns immediately after initiating the requested operation. It is
unsafe to modify or use participating local data before all local
operations have completed. Use the ESMF_VMCommWait() or
ESMF_VMCommQueueWait() method to block the local PET until
local data access is safe again.
Component calls: The behavior of this mode is fundamentally
different for threaded and non-threaded components,
independent on whether the components use shared memory or not.
The ESMF_SYNC_NONBLOCKING mode is the most complex mode for
calling component methods and should only be used if the extra
control, described below, is absolutely necessary.
For non-threaded components (the ESMF default)
calling a component method with ESMF_SYNC_NONBLOCKING
is identical to calling it with ESMF_SYNC_VASBLOCKING. However,
different than for ESMF_SYNC_VASBLOCKING, a call to
ESMF_GridCompWait() or ESMF_CplCompWait() is
required in order to deallocate memory internally allocated for the
ESMF_SYNC_NONBLOCKING mode.
For threaded components the calling PETs
of the parent component will not be blocked and return immediately
after initiating the requested child component method. In this
scenario parent and child components will run concurrently in
identical VASs. This is the most complex mode of operation.
It is unsafe to modify or use VAS local data that
may be accessed by concurrently running components until the child
component method has completed. Use the appropriate
ESMF_GridCompWait() or ESMF_CplCompWait() method to
block the local parent PET until the child component method has
completed in the local VAS.
50.54 ESMF_TERMORDER
DESCRIPTION:
Specifies the order of source terms in a destination sum, e.g. during sparse
matrix multiplication.
The type of this flag is:
type(ESMF_TermOrder_Flag)
The valid values are:
- ESMF_TERMORDER_SRCSEQ
- The source terms are in strict ascending order according to
their source sequence index.
- ESMF_TERMORDER_SRCPET
- The source terms are first ordered according to their distribution
across the source side PETs: for each destination PET the source PET
order starts with the localPet and decrements from there, modulo
petCount, until all petCount PETs are accounted for. The term order
within each source PET is given by the source term sequence index.
- ESMF_TERMORDER_FREE
- There is no prescribed term order. The source terms may be summed in
any order that optimizes performance.
50.55 ESMF_TYPEKIND
DESCRIPTION:

operation that are not mapped by corresponding source points.
- ESMF_UNMAPPEDACTION_IGNORE

ignored and zeros are used for the entries of the sparse matrix
that is generated.
