newbie: Shared Memory (What makes Orbit fast ?)

[Juergen Fuhrmann <fuhrmann wias-berlin de>]

Hi there on the orbit,


I am  currently evaluating  ORBs for a  possible use in  a distributed
numerical simulation environment. 

* Orbit is  described to be  fast on intra-machine  communication. How
this goal has been achieved ?

* Is it possible to use shared  memory transport, are there plans ?  I
looked up the sources and did  not find SystemV IPC (TAO uses this but
the source tree is huuuuge...)


* Is  Orbit able  to handle  messages with  e.g. one  million floating
point values  ?  -- In  the ideal case,  on two machines,  there would
happen something,  and on  a single machine,  the two  processes would
share the memory rather than copy the data.

Juergen
