Botnets have become a top cyber threat. Existing studies on botnets have mainly focused on showing how to exploit certain characteristics of existing botnets to detect them. However, such detection mechanisms could be defeated by stealthy botnets that are designed to evade them. Therefore, it is important to understand the power of stealthy botnets so as to answer questions such as: What kinds of...
Much of high performance technical computing has moved from shared memory architectures to message based cluster systems. The development and wide adoption of the MPI parallel programming model has hastened this transition. Parallel scaling, however, is frequently limited by the inefficient communication hardware commonly found in commodity based clusters. This paper describes a new communication...
The Kautz digraph (Elspas et al., 1968) has been described as the ideal communication network for parallel computers, but it is generally unknown in the engineering community, and has never previously been used in a commercial product. We will define and characterize it in relation to HPC clusters, then discuss some of the implementation issues encountered in developing it as a large-scale cluster...
