### Workshop Description
Modern Big Data increasingly appears in the form of complex graphs and networks. Examples include the physical Internet, the world wide web, online social networks, phone networks, and biological networks. In addition to their massive sizes, these graphs are dynamic, noisy, and sometimes transient. They also conform to all five Vs (Volume, Velocity, Variety, Value and Veracity) that define Big Data. However, many graph-related problems are computationally difficult, and thus big graph data brings unique challenges, as well as numerous opportunities for researchers, to solve various problems that are significant to our communities.
Big graph problems are currently solved using several complementary paradigms. The most popular approach is perhaps by exploiting parallelism, through specialized algorithms for supercomputers, shared-memory multicore and manycore systems, and heterogeneous CPU-GPU systems. However, since real-world graphs are sparse and highly irregular, there are very few parallel implementations that can actually deliver high performance. The major challenges to scaling and efficiency include irregular data dependencies, poor locality, and high synchronization costs of current approaches. In addition to parallelism, researchers are developing approximation algorithms that use sampling for compressing and summarizing graph data. Streaming algorithms are also being considered for scenarios where the rate of updates is too fast to process the entire graph in a single pass. Further, out-of-core algorithms are necessary for massive graphs that do not fit in the main memory of a typical system. Researchers can use graph-based solutions for solving problems from many diverse disciplines, including routing and transportation, social networks, bioinformatics, computational science, health care, security and intelligence analysis.
This workshop aims to bring together researchers from different paradigms solving big graph problems under a unified platform for sharing their work and exchanging ideas. We are soliciting novel and original research contributions related to big graph data management, analysis, and mining (algorithms, software systems, applications, best practices, performance). Significant work-in-progress papers are also encouraged. Papers can be from any of the following areas, including but not limited to:
* Parallel algorithms for big graph analysis on HPC systems
* Heterogeneous CPU-GPU solutions to solve big graph problems
* Extreme-scale computing for large graph, tensor, and network problems
* Sampling and summarization of large graphs
* Graph algorithms for large-scale scientific computing problems

**Distributed Graph Mining in Massive Networks**
**Abstract:** Distributed data processing platforms
such as MapReduce and Pregel have
substantially simplified the design and deployment of certain classes of
distributed graph analytics algorithms. However, these platforms are not
a good match for distributed graph mining problems like mining frequent
subgraphs. Given an input graph, these problems require exploring a very
large number of subgraphs and finding patterns that match some
"interestingness" criteria desired by the user. These algorithms are
very important for areas such as social networks, semantic web, and
bioinformatics.
In this talk I will present Arabesque, a distributed data processing
platform for implementing graph mining algorithms. Arabesque defines a
high-level API that explores subgraphs and passes them to the
application, which must simply compute outputs and decide whether the
subgraph should be further extended. We use Arabesque's API to produce
distributed solutions to three fundamental graph mining problems:
frequent subgraph mining, counting motifs, and finding cliques. Our
implementations require a handful of lines of code, scale to trillions
of subgraphs, and represent in some cases the first available
distributed solutions. I will also talk about techniques to scale graph
mining methods to web-scale networks with billions of nodes and edges.
