ABSTRACT

Graph pattern mining (GPM) is getting increasingly important recently. There are many parallel frameworks for GPM, many of which suffer from performance. GPU is a power- ful option for graph processing, which has excellent potential for performance improvement; however, parallel GPM algorithms produce a large number of intermediate results, limiting GPM implementations on GPU.

In this paper, we present GAMMA, an out-of-core GPM framework on GPU, and it makes full use of host memory to process large graphs. Specifically, GAMMA adopts a self- adaptive implicit host memory access manner to achieve high bandwidth, which is transparent to users. GAMMA provides flexible and effective interfaces for users to build their algorithms. We also propose several optimizations over primitives provided by GAMMA in the out-of-core GPU system. Experimental results show that GAMMA has scalability advantages in graph size over the state-of-the-art by an order of magnitude, and is also faster than existing GPM systems and some dedicated GPU algorithms of specific graph mining problems.

REQUIREMENTS

  • GCC 5.3.0
  • CUDA toolkit 9.0

INPUTS

GAMMA use CSR (compressed sparse rows) as the data structure of graphs. It has two parts: OFFSET and VALUES. The former records the offsets of all adjacency lists in CSR, the latter is the set of all adjacency lists.

The input file of a dataset has two files, data.col and data.dst, which are both binary files. data.col starts with the vertex number of input graph, then follows the OFFSET. So it is as:

${vertex_number} (4 bytes)
${offset_1} (8 bytes)
${offset_2} (8 bytes)
${offset_3} (8 bytes)
… …

data.dst starts with the edge number of input graph, then follows the VALUES. So it is as:

${value_1} (4_byte)
${value_2} (4_byte)
${value_3} (4_byte)
… …
