Send to all in gelly scatter
Hi Is it possible to send a message to all vertices in gelly scatter? How the Ids of all vertices can be found out?
Thanks in advance

I forgot the reference [1] :S

Hi Alieh,
you can send a message from any vertex to any other vertex if you know the
vertex ID. In [1] you will find a table that compares the update logic and
communication scope for all gelly iteration models.
Bear in mind though, that sending a message from all vertices to all other
vertices is a very expensive operation and will not scale to large graphs.
You might need to find another way to express your computation.
Cheers,
-Vasia.

I think you can only send messages to the directly connected vertices.
