Data structure behavior with variable cache size
 Král, Karel ; Koucký, Michal (advisor) ; Mareš, Martin (referee)
Cache-oblivious algorithms are well understood when the cache size remains constant. Recently variable cache sizes have been considered. We are motivated by programs running in pseudo-parallel and competing for a single cache. This thesis studies the underlying cache model and gives a generalization of two models considered in the literature. We give a new cache model called the "depth model" where pages are accessed by page depths in an LRU cache instead of their ad- dresses. This model allows us to construct cache-oblivious algorithms that cause a certain number of cache misses prescribed by an arbitrary function computable without causing a cache miss. Finally we prove that two algorithms satisfying the regularity property running in pseudo-parallel cause asymptotically the same number of cache misses as their serial computations provided that the cache is satisfying the tall-cache assumption.
