Pool and SubPools can be used for remote access ?

Pool and SubPools can be used for remote access ?

[Daniel Norte Moraes]

   Hi!

   I'm learning mpi and openMP and take this insite:
  ? Is possible to use remote data  ( e.g. shared memory , variables etc [
via network and other protocols]) by implementing 
an custom storage_pool's ?  the array in storage pool need be continuous or
an 'fake-length' array is ok ? someone already tried it yet ?

All comments are Wellcome.

[]'of seventy round,
Daniel.

Storage pool can be backed by whatever mechanism. The layout of objects 
allocated in the pool depends on the object. The strategy could be 
mirroring remote objects or using proxy object instead.

As for implementations there exist distributed annex implementations 
which must support remote objects.

There exist persistent storage implementations. Persistent objects 
resemble remote objects in many aspects.

There exist interprocess shared storage pools implementation.

If remote objects should be implemented as stored in a pool is quite 
questionable. Pool is too low level mechanism. Having an object in a 
pool would preclude a lot of functionality, safety and reliability.

 Beyond polyorb, there other implentations ? can you cite some ?

Not that I am aware of. The distributed annex is defined in a way that 
any network protocol could be used if it has RPC or if you could put an 
RPC layer on top of it, even HTTP POST (:-))
