Developed tool was primarily used for performance analysis, targeting Android and Tizen system executables and libraries designed for drawing GUI.
Avalanche − an automatic program traversal and defect detection tool based on Valgrind (dynamic instrumentation framework) − started by program analysis group as a project in 2009. It performs an extensive analysis of a target program by tracing tainted data flow (all external input data received through input streams, file system, network sockets, environment variables and command line arguments, and internal program data derived from external input data) through executed code branching points.
Many hardware-based techniques have been developed for support of increasing data flows: high-speed network channels and memory buses, high frequency CPUs, hard disks with high data density and low access time. However, numerous unsolved problems remain on the software side dealing with processing, analyzing and storing data. This software must use hardware resources efficiently and also satisfy rigid requirements: support batch processing of huge data volumes with high throughput, provide reliable functioning on unreliable hardware, allow for good scaling and efficient random data access. This project is aimed at creating a framework for data acquirement, filtering, analysis and storage in real time on high-speed network channels. This framework will allow automation of a wide range of tasks related to high-speed data flows: classifying traffic, ensuring network security, analyzing social networks, and forecasting using big data.
The idea of the project is to build a solution for processing Big Data collected from numerical simulation of continuum mechanics problems.
Different methods of analysis of random graphs, construction of new mathematical models of scale-free graphs (conforming the so-called power law) is a topical area of research concerning the analysis of networks on the Internet (in particular, social networks such as Facebook, Twitter and many others). However, the properties and parameters of these networks can change. To predict such changes it is necessary to study the general properties of mathematical models of such networks which can be considered as random graphs.

This is why as a part of this project tools for automated testing of network software were developed.

The test reports can present results both in a brief view and with detailed distribution of the errors detected and lists of most serious errors.

New method to provide compatibility for IPv4 and IPv6 protocols fulfilling the draft of the “Stateless IP/ICMP Translator (SIIT)” standard was created and implemented in this project.

The importance of network traffic analysis is constantly increasing because of novel network technologies being developed immediately hitting the market, thus increasing data volume (including personal and sensitive information) transmitted over network by innumerable network applications many of which implement closed application level protocols. Available network analysis tools typically don’t offer generic facilities to inspect application protocols, usually only widespread protocols are supported.
The project is aimed on research and development of the methods for storing, searching and processing of the information taking into account of its complex structure and spatio-temporal semantics. In the scope of the project the decomposition method base on dynamic octrees should be developed and investigated, their complexity should be estimated and recommendations for its practical usage should be elaborated.
Reuse of code fragments, often using in software development. At the level of the source code, it can be part of a program that performs a similar role, but copied with slight modifications. On the binary level it may be object files from libraries are included on the linking stage in the several executable files of the program.
To protect the binary code from analysis are used by many different methods, one of them - obfuscation transformations. Such transformations are usually made with automatic obfuscators, which takes as input the source code or binary file, and output provide an obfuscated executable program.

This system will increase work efficiency and recovery accuracy.
Most of developed tools for analysis for various libraries (MPI, OpenMP) and languages for parallel programming use low level approaches to analyze the performance of parallel applications. There are a lot of profiling tools and trace visualizers which produce tables, graphs with various statistics of executed program. In most cases developer has to manually look for bottlenecks and opportunities for performance improvement in the produced statistics and graphs. The amount of information developer has to handle manually, increase dramatically with number of cores, number of processes and size of problem in application. Therefore new methods of performance analysis fully or partially handling output information will be more beneficial.
