t8_shmem_array_t t8_cmesh_alloc_offsets(int mpisize, sc_MPI_Comm comm)

Allocate a shared memory array to store the tree offsets of a cmesh.

t8_shmem.h

Parameters:

• mpisize – [in] The number of processes.

• comm – [in] The MPI communicator to use. Its mpisize must match mpisize. The shared memory type must have been set. Best practice would be calling sc_shmem_set_type (comm, T8_SHMEM_BEST_TYPE).

Returns:

A t8_shmem_array struct that stores mpisize + 1 t8_gloidx_t entries.
