Did i get it right, does this CPU use the x86-64 ISA ?

(see page 8, Table 2: Configuration of the 256-core system)

It's only simulated at this point.

There are fairly good cycle accurate open source x86 simulators, such as PTLsim or marss86

We use the x86-64 ISA for our cores, yes. But our ideas are applicable beyond the x86 ISA. As nn3 points out, currently our ideas are evaluated in simulation.
