Member Function Documentation

computeSize()

virtual void Arcane::IGatherGroupInfo::computeSize ( Int32 nb_elem_in )

pure virtual

Method allowing the calculation of grouping information.

Collective call.

A second call to this method will have no effect, unless the method needRecompute() was called beforehand.

Parameters

nb_elem_in

The number of elements that our subdomain wishes to send to the master.

Implemented in Arcane::GatherGroupInfo.

isComputed()

virtual bool Arcane::IGatherGroupInfo::isComputed ( )

pure virtual

Method allowing determination of whether the method computeSize() has already been called.

Implemented in Arcane::GatherGroupInfo.

nbElemOutput()

virtual Int32 Arcane::IGatherGroupInfo::nbElemOutput ( )

pure virtual

Method allowing knowledge of the number of elements that our subdomain must process after reception.

Implemented in Arcane::GatherGroupInfo.

nbElemRecvGatherToMasterIO()

virtual SmallSpan< Int32 > Arcane::IGatherGroupInfo::nbElemRecvGatherToMasterIO ( )

pure virtual

Method allowing knowledge of the number of elements that each third-party subdomain will send to us.

Implemented in Arcane::GatherGroupInfo.

nbWriterGlobal()

virtual Int32 Arcane::IGatherGroupInfo::nbWriterGlobal ( )

pure virtual

Method allowing knowledge of the number of writing subdomains.

Implemented in Arcane::GatherGroupInfo.

setNeedRecompute()

virtual void Arcane::IGatherGroupInfo::setNeedRecompute ( )

pure virtual

Method allowing a request for recalculation of grouping information. To do this, the method computeSize() must be called again.

Implemented in Arcane::GatherGroupInfo.

sizeOfOutput()

virtual Int32 Arcane::IGatherGroupInfo::sizeOfOutput ( Int32 sizeof_type )

pure virtual

Method allowing knowledge of the size, in bytes, of the set of elements that our subdomain must process after reception.

Parameters

sizeof_type

The size of an element.

Implemented in Arcane::GatherGroupInfo.
