Neat Stuff

Hi,

  I'm reading out of an overview of research projects at UWashington:

  ".. A new system Opal, attempts to exploit the potential of wide-address
  architectures - processors with 64 bits or more of addressing such as
  the MIPS R4000 and the DEC Alpha.

      "In Opal, all applications execute in one address space. This
  facilitates sharing: a pointer means the same thing to all applications.
  The key point is that having a single address space does not
  compromoise protection: each application executes in a private domain;
  the fact that an application can generate an address does not mean
  that in can read or write that address. Protection domains are
  composed of multiple segments; segments are the basic unit of sharing."

Anyone looking at the Alpha platform? :-)
