Performance and Scalability of Emerging Shared Memory Parallel Architectures
10:00 AM-12:30 PM
Room: Ballroom C
In the next few years, at least three vendors will introduce new
computer systems that implement the abstraction of a shared memory
parallel programming paradigm. Each of the systems will be
configurable with up to thousands of nodes and capable of executing
large-scale parallel scientific computations with a
globally-addressable memory. However, each machine will implement the
shared memory abstraction in a different way. In the details of these
implementations, differences lie potential performance variations of
one to two orders of magnitude, as well as significant ease of use
issues for parallel program developers. It has not been demonstrated
that performance on these shared memory architectures will scale to
large numbers of processors. The speakers in this minisymposium will
discuss system-level architecture, performance metrics, usability,
and application performance.
