In this paper, we prove topology dependent bounds on the number of rounds needed to compute Functional Aggregate Queries ($\FAQ$s) studied by Abo Khamis et al. [PODS 2016] in a synchronous distributed network under the model considered by Chattopadhyay et al. [FOCS 2014, SODA 2017]. Unlike the recent work on computing database queries in the Massively Parallel Computation model, in the model of Chattopadhyay et al., nodes can communicate only via private point-to-point channels and we are… Expand

Algorithms for a Topology-aware Massively Parallel Computation Model
• Computer Science
• PODS

This work focuses on network topologies that are tree topologies, and presents both lower bounds as well as (asymptotically) matching upper bounds, and takes the first step into investigating three fundamental data processing tasks in this topology-aware parallel model: set intersection, cartesian product, and sorting.

Rectangles Are Nonnegative Juntas

The main structure theorem states that each rectangle in the communication matrix of f o gn can be simulated by a nonnegative combination of juntas, the strongest yet formalization for the intuition that each low-communication randomized protocol can only "query" few inputs of f as encoded by the gadget g.

This paper proves lower bounds on randomized multiparty communication complexity, both in the blackboard model and in the message-passing model, and introduces a new technique for proving such bounds, called symmetrization, which is natural, intuitive, and often easy to use. Expand

It is shown that for a large class of natural functions like Set-Disjointness the communication cost is essentially n times the cost of the optimal Steiner tree connecting the terminals, and for natural composed functions like Element-Distinctness ED and XOR the naive protocols suggested by their definition is optimal for general networks.
