* @class vtkPExtractExodusGlobalTemporalVariables
|
|
* @brief parallel version of vtkExtractExodusGlobalTemporalVariables.
|
|
*
|
|
* vtkPExtractExodusGlobalTemporalVariables is a parallel version of
|
|
* vtkExtractExodusGlobalTemporalVariables that handles synchronization between
|
|
* multiple ranks. Since vtkPExodusIIReader has explicit sycnchronization
|
|
* between ranks its essential that downstream filters make consistent requests
|
|
* on all ranks to avoid deadlocks. Since global variables need not be provided
|
|
* on all ranks, without explicit coordination
|
|
* vtkExtractExodusGlobalTemporalVariables may end up not making requests on
|
|
* certain ranks causing deadlocks.
