BoF session at SC14, November 16-21, 2014, New Orleans LA, USA:

Code Optimization War Stories

 

Session Leaders:

Abstract:

Code optimization is essential for the efficient use of highly parallel systems, small clusters, and even desktop machines. Although there is a trend in HPC research towards automatic tuning tools, most of these efforts are still hard work done by domain scientists or performance experts in computing centers. However, code optimization is often not regarded as novel scientific contribution, so many of these activities go unpublished and unnoticed beyond a very small community. With this BoF we want to reach developers from diverse fields of domain and computer science to share and discuss interesting, educational “war stories” in code optimization.
