Hi Steve,
Thanks very much for your reply.
You're welcome. Please reply to the mailing list and not directly to
me. That way if others have similar problems they can learn from the
mailing list archives.
Both of my programs are running successfully. Now I have compiled both
the programs with the '-static' option and they are running okay when i
am not using the printf() in the code. But when I am using printf(), it
is giving me an error " System call 427 out of range". I checked tthe
code and found that the function pointer for printf() is not
implemented. So do I have to implement printf() and similarly other
functions like fork(), pthread_create() etc on my own if I use them in
my code?
System call 427 is fstat64. This is implemented in m5 2.0 (but not in 1.1).
printf() is implemented in libc, which should be statically linked in to
your binary. I don't know what you mean by "the function pointer for
printf() is not implemented".
pthread_create()/fork() is a different issue; if you want to run general
pthreads programs then you'll need to run them under full system mode,
as there isn't (and probably never will be) a thread scheduler built
into m5. (There's a perfectly good one in the Linux kernel, and since
we can run that, there's not a lot of motivation to do another one.) If
you just want to run simple SPLASH-like programs, that's not
unthinkable, but right now the only way to do that in SE mode is if you
can compile them under Tru64. Linux SE-mode PARMACS support is on my
to-do list but unfortunately behind a few other things.
Can you tell me the way to run two different programs in two different
cores?
Set the workload parameter of each cpu to the workload you want to run,
e.g.:
cpu[0].workload = Benchmarks.AnagramLongCP()
cpu[1].workload = Benchmarks.GCCLongCP()

Getting the deadlock message at cycle 0 basically means that the CPU
never really started executing instructions. One common cause for this
is that your programs are not statically linked; see

You should verify that both programs run successfully by themselves
before trying to run them both together.
BTW, specifying two programs in a list like you have there is
specifying
two programs for a two-way multithreaded CPU, not for two different
cores.
