class vtkMPIController
 

Detailed Description

Class for creating user defined MPI communicators.

This class can be used to create user defined MPI communicators. The actual creation (with MPI_Comm_create) occurs in Initialize which takes as arguments a super-communicator and a group of process ids. The new communicator is created by including the processes contained in the group. The global communicator (equivalent to MPI_COMM_WORLD) can be obtained using the class method GetWorldCommunicator. It is important to note that this communicator should not be used on the processes not contained in the group. For example, if the group contains processes 0 and 1, controller->SetCommunicator(communicator) would cause an MPI error on any other process.

◆ SetUseSsend()

virtual void vtkMPICommunicator::SetUseSsend ( int  )
virtual

When set to 1, all MPI_Send calls are replaced by MPI_Ssend calls.

Default is 0.

◆ GetUseSsend()

virtual int vtkMPICommunicator::GetUseSsend ( )

When set to 1, all MPI_Send calls are replaced by MPI_Ssend calls.

Default is 0.

When set to 1, all MPI_Send calls are replaced by MPI_Ssend calls.

Default is 0.

◆ UseSsendOff()

virtual void vtkMPICommunicator::UseSsendOff ( )

Default is 0.

◆ CopyFrom()

void vtkMPICommunicator::CopyFrom ( vtkMPICommunicator source)

Copies all the attributes of source, deleting previously stored data.

The MPI communicator handle is also copied. Normally, this should not be needed. It is used during the construction of a new communicator for copying the world communicator, keeping the same context.

◆ InitializeNumberOfProcesses()

int vtkMPICommunicator::InitializeNumberOfProcesses ( )
protected

◆ SetKeepHandle()

virtual void vtkMPICommunicator::SetKeepHandle ( int  )
protectedvirtual

KeepHandle is normally off.

This means that the MPI communicator handle will be freed at the destruction of the object. However, if the handle was copied from another object (via CopyFrom() not Duplicate()), this has to be turned on otherwise the handle will be freed multiple times causing MPI failure. The alternative to this is using reference counting but it is unnecessarily complicated for this case.

◆ KeepHandleOn()

virtual void vtkMPICommunicator::KeepHandleOn ( )
protectedvirtual

KeepHandle is normally off.

This means that the MPI communicator handle will be freed at the destruction of the object. However, if the handle was copied from another object (via CopyFrom() not Duplicate()), this has to be turned on otherwise the handle will be freed multiple times causing MPI failure. The alternative to this is using reference counting but it is unnecessarily complicated for this case.

◆ KeepHandleOff()

virtual void vtkMPICommunicator::KeepHandleOff ( )
protectedvirtual

KeepHandle is normally off.

This means that the MPI communicator handle will be freed at the destruction of the object. However, if the handle was copied from another object (via CopyFrom() not Duplicate()), this has to be turned on otherwise the handle will be freed multiple times causing MPI failure. The alternative to this is using reference counting but it is unnecessarily complicated for this case.

◆ InitializeCopy()

void vtkMPICommunicator::InitializeCopy ( vtkMPICommunicator source)
protected

◆ Duplicate()

void vtkMPICommunicator::Duplicate ( vtkMPICommunicator source)
protected

Copies all the attributes of source, deleting previously stored data EXCEPT the MPI communicator handle which is duplicated with MPI_Comm_dup().

Therefore, although the processes in the communicator remain the same, a new context is created. This prevents the two communicators from intefering with each other during message send/receives even if the tags are the same.
