| Abstract | Billion-node graphs are rapidly growing in size in many applications such as online social networks. Most graph algorithms generate a large number of messages during iterative computations. Vertex-centric distributed systems usually store graph data and message data on disk to improve scalability. Currently, these distributed systems with disk-resident data take a push-based approach to handle messages. This works well if few messages reside on disk. Otherwise, it is I/O-inefficient due to expensive random writes. By contrast, the existing memory-resident pull-based approach individually pulls messages for each vertex on demand. Although it can be used to avoid disk operations regarding messages, expensive I/O costs are incurred by random and frequent access to vertices. This paper proposes a hybrid solution to support switching between push and pull adaptively, to obtain optimal performance for distributed systems with disk-resident data in different scenarios. We first employ a new block-centric technique (b-pull) to improve the I/O-performance of pulling messages, although the iterative computation is vertex-centric. I/O costs of data accesses are shifted from the receiver side where messages are written/read by push to the sender side where graph data are read by b-pull. Graph data are organized by clustering vertices and edges to achieve high I/O-efficiency in b-pull. Second, we design a seamless switching mechanism and a prominent performance prediction method to guarantee efficiency when switching between push and b-pull. We conduct extensive performance studies to confirm the effectiveness of our proposals over existing up-to-date solutions using a broad spectrum of real-world graphs. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
