reserveDomain() [1/2]

virtual void splash::IParallelDomainCollector::reserveDomain ( int32_t  id, const Dimensions  globalSize, uint32_t  ndims, const CollectionType &  type, const char *  name, const Domain  domain, DomDataClass  dataClass  )

pure virtual

Reserves a dataset with annotated domain information for parallel access.

Parameters

id	ID for iteration.
globalSize	Global size for reserved dataset.
ndims	Number of dimensions (1-3).
type	Type information for data.
name	Name for the dataset.
domain	Global domain information.
dataClass	Subdomain type annotation.

Implemented in splash::ParallelDomainCollector.

reserveDomain() [2/2]

virtual void splash::IParallelDomainCollector::reserveDomain ( int32_t  id, const Dimensions  size, Dimensions *  globalSize, Dimensions *  globalOffset, uint32_t  ndims, const CollectionType &  type, const char *  name, const Domain  domain, DomDataClass  dataClass  )

pure virtual

Reserves a dataset with annotated domain information for parallel access.

The global size and the global offset for the calling process are determined automatically via MPI among all participating processes. Note: This is not possible when writing 2D data with a 3D MPI topology.

Parameters

id	ID for iteration.
size	Global size for reserved dataset.
globalSize	Returns the global size of the dataset, can be NULL.
globalOffset	Returns the global offset for the calling process, can be NULL.
ndims	Number of dimensions (1-3).
type	Type information for data.
name	Name for the dataset.
domain	Global domain information.
dataClass	Subdomain type annotation.

Implemented in splash::ParallelDomainCollector.

writeDomain() [1/2]

virtual void splash::IParallelDomainCollector::writeDomain ( int32_t  id, const CollectionType &  type, uint32_t  ndims, const Selection  select, const char *  name, const Domain  localDomain, const Domain  globalDomain, DomDataClass  dataClass, const void *  buf  )

pure virtual

The global size and the write offset for the calling process are determined automatically via MPI among all participating processes. Note: This is not possible when writing 2D data with a 3D MPI topology.

The global domain size and the domain offset for the calling process are determined automatically via MPI among all participating processes.

Implements splash::IDomainCollector.

Implemented in splash::ParallelDomainCollector.

writeDomain() [2/2]

virtual void splash::IParallelDomainCollector::writeDomain ( int32_t  id, const Dimensions  globalSize, const Dimensions  globalOffset, const CollectionType &  type, uint32_t  ndims, const Selection  select, const char *  name, const Domain  globalDomain, DomDataClass  dataClass, const void *  buf  )

pure virtual

Writes data with annotated domain information.

Parameters

id	ID for iteration.
globalSize	Dimensions for global collective buffer.
globalOffset	3D-offset in the globalSize-buffer this process writes to.
type	Type information for data.
ndims	Number of dimensions (1-3) of the buffer.
select	Selection in src buffer.
name	Name of the dataset.
globalDomain	Global domain information.
dataClass	Domain type annotation.
buf	Buffer with data.

Implemented in splash::ParallelDomainCollector.
