Workshop on Extreme-scale Performance Tools

SC 12


November 16, 2012


in conjunction with
Supercomputing 2012
Salt Lake City, Utah

As we approach exascale, the rising architectural complexity coupled with severe resource limitations with respect to power, memory and I/O, makes performance optimization more critical than ever before. However, all the challenges of scalability, heterogeneity, and resilience that application and system developers face will also affect the development of the tool environment needed to achieve performance objectives. This workshop will serve as a forum for application, system, and tool developers to discuss the requirements of future exascale-enabled performance tools and the roadblocks that need to be addressed on the way.

The workshop is organized by the Virtual Institute - High Productivity Supercomputing, an international initiative of publicly-funded HPC programming-tool builders aimed at the enhancement, integration, and deployment of their products. The event will focus not only on technical issues but also on the community-building process necessary to create an integrated performance-tool suite ready for an international exascale software stack.
