Your short-term

Lazy as I am, I haven't tried to find out by myself, I ask instead:
how does the M5 syscall emu run multithreaded apps? Seems that clone()
is unimplementedFunc. Hmm.. did I just find it out? :-)
The SMT model currently only supports multiprogrammed workloads (i.e.
multiple independent single-threaded processes), which is why the ASID
matters there. You can run individual multithreaded apps on a
multiprocessor of single-threaded CPUs, but not on an SMT CPU... not
that it's hard, just the code doesn't quite support it.
I was just wondering how the threads would be scheduled.. I suppose
using full system simulation might be more feasible for multithreaded
apps.
If you're interested in dynamic thread scheduling, you will want to use
the OS. Unfortunately that doesn't support SMT right now either... even
though Linux has SMT support it's all in the x86-specific part of the
code and hasn't been ported to Alpha.
