Description:

miniTri is a proxy for a class of triangle based data analytics (Mantevo). This simple code is a self-contained piece of C++ software that uses triangle enumeration with a calculation of specific vertex and edge properties. Key uses related to miniTri include dense subgraph detection, characterizing graphs, improving community detection, and generating graphs. Related applications exist in cyber security, intelligence, and functional biology. miniTri attempts to be more application relevant than standard data analytics benchmarks such as Graph 500.

The objective of the miniTri miniapp is to calculate a specific number (k) for all triangles in the graph. miniTri has the following basic steps (some of which can be combined):

  1. Find all triangles in the graph;
  2. For all triangles in the graph, calculate the vertex triangle degrees;
  3. For all triangles in the graph, calculate the edge triangle degrees; and
  4. For all each triangle, calculate integer k given triangle degree info.

From these k values, an upper bound on the largest clique in the graph can be calculated.
