Macro Definition Documentation

T8_CMESH_FORMAT

#define T8_CMESH_FORMAT   0x0002

Increment this constant each time the file format changes.

We can only read files that were written in the same format.

Typedef Documentation

t8_load_mode_t

typedef enum t8_load_mode t8_load_mode_t

This enumeration contains all modes in which we can open a saved cmesh.

The cmesh can be loaded with more processes than it was saved and the mode controls, which of the processes open files and distribute the data.

Enumeration Type Documentation

t8_load_mode

enum t8_load_mode

This enumeration contains all modes in which we can open a saved cmesh.

The cmesh can be loaded with more processes than it was saved and the mode controls, which of the processes open files and distribute the data.

Enumerator
T8_LOAD_SIMPLE	In simple mode, the first n processes load the file.
T8_LOAD_BGQ	In BGQ mode, the file is loaded on n nodes and from one process of each node. This needs MPI Version 3.1 or higher.
T8_LOAD_STRIDE	Every n-th process loads a file. Handle with care, we introduce it, since on Juqueen MPI-3 was not available. The parameter n has to be passed as an extra parameter. See also t8_cmesh_load_and_distribute
