Title:
How to commercialize theoretical research.
And also some interesting math about memory hierarchies 

Abstract:
The Memory Hierarchy consists of all the parts of the memory subsystem of a 
computer, as well as algorithms for moving information around in memory, such 
as for caching and prefetching.  Memory effects can easily dominate 
computation time in many settings, since memory accesses are typically so much
slower than the other parts of a computation.  However, explicitly optimizing 
code for memory effects can be a painstaking and specialized skill.  I'll be 
presenting Cache-Oblivious Algorithmics, an approach for understanding memory 
and for writing high-performance memory-intensive code.
