Compiler directed Page coloring

["Sarnath Kannan" <sparc64 at rediffmail dot com>]

Hi,
 I am new to this group.
 For quite a while, I have been thinking about "compiler
 directed page coloring" which could be used to enhance
 performance of GNU/Linux system. One can implement 
page-coloring
 in the Linux kernel with the help of 
application-specific-inputs
 from GCC. Such models had already been researched and 
investigate by
 many scholars. (Please check out "citeseer" and Google for more 
info)

 I have a few questions:
 1) Is this mailing list the correct place for this suggestion 
?
 2) Are any of you interested in this idea ?
 3) If so, What sort of inputs can GCC to the kernel w.r.t page
    coloring ? Can It be done ? I think "Flow graphs",
    "tracking data access, and other subtle nuances come into 
picture.
    Can such information be given by GCC ? I dont know anything 
about
    GCC internals. I am a mere user.
 4) In case one starts to implement, we need to take help from 
the
    linux-kernel guys so that we evolve a proper model for this 
and
    develop the entire thing independently. People from both 
areas
    may need to work in testing/benchmarking etc.. So Is this 
all
    possible (given the limited resources of developers and 
their
    work load)

Thanks for any feedback,
Pardon me if this is out of context of the group.
