Consept and technology of parallel programming for heterogeneous system on chip
Abstract
Common Many-Core SoC architectures is a quick-growing segment of distributed parallel computing systems. Such systems cannot be effectively programmed manually , however there are only basic instruments and tools for programming.
In this article we propose the concept of Many-Core SoC parallel programming. The concept presents visual programming approach, medium-grained parallel program organization with sequential grains and dynamics of parallel computation. The article suggests the set of tools named VIPE: VPL Integrated Programming Environment. VIPE includes strict mathematical formal model basis, visual parallel programming language for medium-grained programs design, toolset for mapping, translating and pre-compiling of the program scheme and the Many-Core SoC simulation software.

Testing of aluminum-silicon alloys mechanical properties on separately casted specimens
Abstract
The mechanical properties of aluminum alloys before casting into moulds were determined on separately casted control specimens casted in horizontal or vertical forms. A comparison of the mechanical properties (tensile strength t, elongation 8, hardness HB) of 12-mm-diameter individually casted of AK7ch alloy control specimens and its density in the solid state (p) showed that it is necessary to use specimens casted in a horizontal mold for evaluation of castings quality.
It was estimated that position of separately casted test samples in the foundry metal form influences the indicators of mechanical properties of aluminium-silicon alloys.
