Fibers as the basis for the implementation of the notion of the T-process for the JVM platform

The spread and the accessibility of modern parallel computing platforms shows the lack of an appropriate support level of the needs of software developers for the parallel applications implementation. At PSI RAS the approach is under development to parallelization of programs based on the use of the computation model named “self-transformation of computational network”. This paper discusses the various options for approaches to the implementation of the notion “T-process”–one of the basic notions of the computation model–for the JVM platform. The potential problems are analyzed associated with the implementation of the “ T-process” notion on the basis of the classical OS/JDK threads, and in the event of a lightweight threads are supported directly in the virtual machine code. The approach to the implementation of the T-processes is proposed based on the use of the concept of the fibers, i.e. lightweight threads, which are implemented outside the JVM code. The results of experimental comparison of different approaches to the implementation of the notion of “T-process” based on the use of fibers and classical streams are provided. We also analyze the effect of the use of fibers in the implementation of the “self-transformation of the computational network” computation model which is used in the ajl parallel programming language being developed for the JVM platform.
