Native execution isn't supported on any of our architectures including
Alpha. I would imagine x86 will be the first architecture to get
native execution support.

I know the M5 developer community is working on full-system
simulation for MIPS and ARM (and even X86 down the road.) Does it
seem like anyone is working on "native execution" for any CPU model
besides the Alpha?
Thanks again,

You can do single processor full-system simulation on SPARC and
boot Solaris. In theory multi-processors should work -- the code
is written -- but it hasn't been tested/debugged. If you're
interested in doing it we have some infrastructure to do cycle
checking Legion (Sun's functional simulator) that we can share.
There is currently no support for native execution on SPARCs.
(2) Simulation speed. I need a sense of both the software and
hardware performance in instructions/second. This is a critical
piece of information and I have not found it anywhere in the docs
or tutorial. I would even accept anecdotal information about M5
speed.
We get about 2M IPS on a simple CPU model. Full-system isn't
supported on our out-of-order model, but it would be a good bit
slower.
