Web6 Introduction to spectral partitioning and Cheeger’s Inequality Today and next time, we will cover what is known as spectral graph partitioning, and in particular we will discuss and prove Cheeger’s Inequality. This result is central to all of spectral graph theory as well as a wide range of other related spectral graph methods. WebFirst, using a graph partitioning based block distribution between grid sites gives lower communication time compared to the random block distribution. This can be inferred by just looking at total interface size of the mesh blocks distributed between Grid sites or actual time measurement which also includes communication latency and wait time.
