Seminar: Riko Jacob, IT University of Copenhagen, “Sparse Grids and the I/O-Model: How Theory Helps”

Starting from the observation that quite frequently the memory system is the performance bottleneck, I will discuss a typical memory efficient algorithm, namely the classical one for dense matrix multiplication. Then I will briefly sketch how similar ideas are helpful in the setting of Sparse Grids (I’ll explain what that is too), and report on experiments we did with this memory efficient algorithm.
