Programming technology for hybrid computer systems
Combination of nodes with different architecture within a hybrid computer system theoretically allows increasing of real performance and efficiency of calculations but considerably complicates programming of the system as a single complex, because programming paradigms of different computational architectures are different. Programming of hybrid computer systems requires a new technology which allows description in one and the same language and automatic transformation of various forms of organization of parallel calculations. The paper addresses the solution of this scientific problem. The paper deals with methods of reduction of the computer system performance for transformation of forms of organization of calculations and scaling of the parallel program by taking into account the variable hardware resource. While reducing the performance, the proportional reduction of the performance is made for all without exception fragments of the task information graph at the expense of reduction of the number of operations performed simultaneously, or reduction of the size of the processing data, or reduction of the number of used data channels. In several cases it leads to a reduction of the hardware resource required for the implementation of computational structure. The basis of the developed technology of resource-independent programming is a high-level programming language COLAMO, which allows description of various forms of organization of parallel calculations such as structural, structural-procedural, multiprocedural and procedural forms for organization of calculations. Transformations between these various forms of organization of calculations for fast computer-aided adaptation of the application to the modified configuration of hardware resource of the computer system is performed with the help of a special software tool - a pre-processor of the high-level programming language COLAMO, which reduces the fragments of the parallel program, selected by the developer with the help of special keywords. At present, we analyze functionality and efficiency of the developed prototype for the pre-processor of the high-level programming language COLAMO and implementing tests of digital signal processing, symbol processing as well as computer network monitoring on a hybrid computer system.
