In this article, the bubble scheduling and allocation algorithm is considered for different types of topologies: grid, hypercube, de Bruijn topology, extended de Bruijn topology based on ternary code. Static planning algorithms are analyzed; the results are presented in the form of a comparative table on the criteria of complexity, the need to find a critical path, the presence of a table of routing and efficiency. The study of the method of planning calculations is carried out based on the problem of finding the roots of systems of linear and nonlinear equations using Cramer’s and Newton’s methods. The corresponding graphs of tier-parallel form are synthesized for these methods. The principles of synthesis for 4 types of topologies are shown. The synthesis of the grid, hypercube, and de Bruijn graph is considered in the classical form. The synthesis of the extended de Bruijn topology is a synthesis of de Bruijn topology [1, 2] using a ternary code. That is, with the same number of processors, the number of connections increases. Experimental studies of the scheduling of the obtained graphs in the synthesized topologies using the method of bubble scheduling and allocation are conducted; the results of scheduling are presented for these topologies. The best results were shown by extended de Bruijn topology based on ternary code due to the increased degree of units, which is especially noticeable for Newton’s method where there are much more data transfers than in Cramer’s method. The topology of a hypercube and de Bruijn topology demonstrated just about same results but hypercube topology did a little better. In addition to this, having a smaller diameter and cost, the hypercube is the most optimal topology and still used today. However, when constructing fail-safe topological organizations, it is better to use topologies based on ternary code, such as the topology based on the extended de Bruijn graph.

Given the ever-increasing amount of high-dimensional and complex omics data becoming available, it is increasingly important to discover simple but effective methods of analysis. Divergence analysis transforms each entry of a high-dimensional omics profile into a digitized (binary or ternary) code based on the deviation of the entry from a given baseline population. This is a novel framework that is significantly different from existing omics data analysis methods: it allows digitization of continuous omics data at the univariate or multivariate level, facilitates sample level analysis, and is applicable on many different omics platforms. The divergence package, available on the R platform through the Bioconductor repository collection, provides easy-to-use functions for carrying out this transformation. Here we demonstrate how to use the package with data from the Cancer Genome Atlas.
