Hi all,
I would like to know why well-known data structures such as linked
lists, binary trees, and other kinds of intelligent forms of storing data in main
memory aren't usually used in clusters or parallel programming.
I'm telling this because I've been examining some MD programs in search
of such data structures and I can't find any of them. This could be
because there is no need for these structures, but I doubt it since these programs
are usually managing huge amounts of information like atoms, etc...
I was reading somewhere that parallel programmers don't like pointers,
what is in fact esential for dynamic data structures, because they won't
be able to predict the use of memory, leading to a loss of eficiency.
After reading some information about MPI programming, I actually think
that it could be possible to implement data structures for these parts of
the parallel calculation that are running localy in a node. Maybe I'm
wrong. Could anyone help ?
Thank you in advance.
