The architectural complexity in HPC is growing and this brings various challenges such as tight power budgets, variability in CPU clock frequencies, load balancing in heterogeneous systems, hierarchical memories and shrinking I/O bandwidths. This is especially prominent on the path to Exascale. Therefore, tool support for debugging and performance optimization becomes more necessary than ever. However, the challenges mentioned above also apply to tool development and, in particular, raise the importance of topics such as automatic tuning and methodologies for tool-aided application development. This workshop will serve as a forum for HPC application developers, system designers, and tool researchers to discuss the requirements for Exascale-enabled tools and the roadblocks that need to be addressed on the way. We also highly encourage application developers to share their experiences using existing tools. The event will serve as a community forum for everyone interested in interoperable tool sets ready for an Exascale software stack.
