k Abstract:
Modern operating system advanced topics: DTrace. The kernel

internals of the Solaris Dynamic Tracing facility (DTrace)
will be

examined. DTrace is more than just a tool -- it
is an extensible framew

ork making it an interesting case
study in applied software engineerin

g. In addition several
of the DTrace providers exploit features unique
to the hardware
architectures on which they run making their algorith

ms
interesting case studies.
