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.
