a Shoebox: The Convergence of High-Performance Computing (HPC) and
High-Performance Embedded Computing (HPEC)

The majority of the world's computing is performed in embedded systems
(wireless apps, network routers, set-top boxes, etc.). Larger and
larger parallel embedded systems are being deployed and the world
of High-Performance Embedded Computing (HPEC) is increasingly dealing
with traditional HPC issues (bisection bandwidth, shared vs. distributed
memory, scalable software, etc.). The increasing physical size of
today's largest HPC systems is problematic for all but a few users.
Increasingly the HPC community is dealing with traditional HPEC
issues (Mflops/ft3, Mflops/watt, etc.). This panel will introduce
these issues and will discuss how they relate to both the HPC and
HPEC communities. Questions that will be addressed include:
DENSITY: HPEC systems
provide a 10x increase in Mflops/ft3 over their HPC counterparts.
Is the need for compute density limited to special-purpose applications,
or will high-density computing be required for next-generation
supercomputers to be feasible?
CONVERGENCE: HPC systems
are increasingly becoming more focused on density while HPEC systems
are becoming more focused on programmability. Will these two regimes
GROWTH: Both HPC and
HPEC are driven by commercial and DoD markets (servers, medical,
wireless, etc.). Will one of these areas become so dominant as
to create a "victor"?
