Detailed Description

We define here the datatypes needed for internal forest routines.

Macro Definition Documentation

T8_PROFILE_NUM_STATS [1/2]

#define T8_PROFILE_NUM_STATS   14

The number of statistics collected by a profile struct.

This struct is used to profile forest algorithms.

The forest struct stores a pointer to a profile struct, and if it is nonzero, various runtimes and data measurements are stored here.

See also

t8_cmesh_set_profiling and

t8_cmesh_print_profile The number of statistics collected by a profile struct.

T8_PROFILE_NUM_STATS [2/2]

#define T8_PROFILE_NUM_STATS   14

The number of statistics collected by a profile struct.

This struct is used to profile forest algorithms.

The forest struct stores a pointer to a profile struct, and if it is nonzero, various runtimes and data measurements are stored here.

t8_cmesh_set_profiling and

t8_cmesh_print_profile The number of statistics collected by a profile struct.

Typedef Documentation

t8_forest_from_t

typedef int8_t t8_forest_from_t

If a forest is to be derived from another forest, there are different possibilities how the original forest is modified.

Currently we support: Copying, adapting, partitioning, and balancing a forest. The latter 3 can be combined, in which case the order is

1. Adapt, 2. Partition, 3. Balance. We store the methods in an int8_t and use these defines to distinguish between them.
