요약In today's data-driven world and heterogeneous computing environments processing large-scale graphs in an architecture agnostic manner has become more important than ever before. Therefore, there has been a significant interest in high-performance graph processing. Traditionally, hand-optimized high-performance computing (HPC) solutions have been studied and used to implement highly efficient and scalable graph algorithms. In recent years, after the big data movement, to bring parallel computing to the masses, researchers also proposed several graph processing and management systems to handle large-scale graphs. Hand optimized HPC approaches require high expertise and graph processing frameworks suffer from expressibility and performance. Both approaches have portability issues.This work proposes that block-based graph algorithms offer a sweet spot between efficient parallelism and architecture agnostic algorithm design for a wide class of graph problems that performs close to hand-optimized HPC implementations.In this work, we first show how we can solve graph merging and triangle counting problems using block-based approaches. First, we propose a partitioning for the computation space to solve the graph merging problem. We propose a novel, fast graph merging algorithm, and a data-parallel, architecture (resource)-aware scalable graph merging framework. Second, we propose a coarse-grained triangle counting algorithm for shared-memory multicore machines. That algorithm aims to increase cache locality by considering the natural order of the given graphs to partition the computation among threads. However, coarse-grain approaches perform poorly on distributed and (or) heterogeneous environments. Therefore, we propose a specific 2D partitioning strategy, named as symmetric rectilinear partitioning and a medium-grained triangle counting formulation on top of this partitioning which makes the algorithm naturally suitable for task-based execution on shared and distributed-memory systems as well as on heterogeneous architectures.Furthermore, using proposed partitioning and parallelization strategies, we propose a block-based algorithmic framework for parallel graph processing on heterogeneous platforms; PGAbB. In a heterogeneous setting, PGAbB aims to maximally leverage from different architectures by implementing a task-based execution on top of a block-based programming model. We further propose algorithmic optimizations for scheduling, load-balancing, and reducing the data-movement complexities of these applications for real-world inputs.
