Hi,

I have a linux network and i would like to know if they are a D 
library to  communicate between computer efficiently.

I do not know if that is better to use websocket and if they 
exists into dlang:

you could use websocket in D but if you are talking between two 
separate D programs you can just use a regular socket

http://dlang.org/phobos/std_socket.html

If you have a copy of my book, I have a brief how-to on 
std.socket in chapter 2. But for two computers just talking to 
one another all you have to do is on one:

new Socket
bind
accept

and on the other one:

new Socket
connect


See the documentation for info on each of those methods.

It's an application and network dependant decision, but I would 
suggest http://code.dlang.org/packages/zmqd as suitable for most 
situations.

Yeah, this would be my first choice.  Or HTTP if integration with 
other applications is an option.  I really like JSON-RPC, though 
it seems to not get much attention.  Longer term, I'd like to 
extend the messaging in std.concurrency to allow interprocess 
communication as well.

An MPI backend for std.concurrency would be a game-changer for D 
in certain scientific circles.

Note: I don't have much love for MPI, but it's the only practical
option on many clusters currently.

Pragmatically, I think this would be a good idea=E2=80=A6

=E2=80=A6philosophically MPI sucks.

The problem is that C, C++, Fortran, Chapel, X10 all assume MPI is the
cluster transport.

Fortunately in the Groovy, GPars, Java, Scala, Akka world, there are
other options, ones that are much nicer :-)

Sadly, I don't have time to contribute to any constructive work on this
just now. And I ought to be doing a review and update to
std.parallelism=E2=80=A6

That's fine.  I have zero free time until August.

Not efficient in any means, but DHSL allows to create super 
simple webservers.
