**m Connectivity/alloc_conn

NAME alloc_conn USAGE call alloc_conn(a2b,nel=nv,nconn=nedg)

DESCRIPTION Constructor. (re)Allocates a connectivity table.

INPUTS a2b :: type(connectivity) The connectivity to be allocated; reused if already available. nel :: integer Number of items (vertices) to be connected nconn :: integer Number of connections (edges)

**m Connectivity/free_conn

NAME free_conn USAGE call free_conn(a2b)

DESCRIPTION Destructor

INPUTS a2b :: type(connectivity) The connectivity to be destroyed;

**f Connectivity/bcast_conn

NAME bcast_conn USAGE

 call bcast_conn(a2b)

DESCRIPTION Distribute a copy of the connectivity from process 0 to everybody else.

INPUTS a2b :: type(connectivity) The connectivity to be broadcast;

**m Connectivity/get_ith_conn

NAME get_ith_conn USAGE call get_ith_conn(ith_conn,a2b,i)

DESCRIPTION Getter. Access the I-th row in the connectivity table. Returns a pointer to the requested row. Note: returning a pointer and not a copy, because it is used in tight loops; user should NEVER modify nor deallocate the returned pointer.

INPUTS a2b :: type(connectivity), intent(in), target The connectivity to be accessed; i :: integer Request access to the I-th row; OUTPUT ith_conn(:) :: integer, pointer A pointer to the i-th row;

**m Connectivity/get_conn_csr

NAME get_conn_csr USAGE call get_conn_csr(a2b,lookup,conn)

DESCRIPTION Get a full copy of the connectivity table in CSR format. Being a copy the user may do as he/she pleases with it, and should remember to deallocate it.

INPUTS a2b :: type(connectivity), intent(in) The connectivity to be accessed; OUTPUT lookup(:) :: integer, allocatable conn(:) :: integer, allocatable A copy of the lookup table. The neighbours of item I are listed at CONN(lookup(i):lookup(i+1)-1)

Graph Key

Nodes of different colours represent the following:

Solid arrows point from a submodule to the (sub)module which it is descended from. Dashed arrows point from a module or program unit to modules which it uses. Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.
