Ah. Sounds good (-;

Is there a release date for Cactus 5?

So currently one is restricted to primitive datatypes? Sending C++  
Objects is not possible? Sounds like MPI to me (-;

Well, I am looking for a mature framework which we can extend to  
couple various legacy (and also new) simulations, mostly cellular  
automata.
I am just not sure if Cactus is suitable. Is it possible to execute  
the thorns on different machines and architectures? e.g One thorn on  
a linux hpc cluster, another on a local machine, another distributed  
on a grid.
Is it possible to establish a peer to peer connection between thorns,  
or does one have to use the flesh for this?

Cheers,
