Pcynlitx is an outcome of a scientific research project and it is distributed with GPLv3 open-source software licence. You can find the source code of the platform from the links which are given in below.
THE PCYNLITX PLATFORM
The pcynlitx platform offers a new programming paradigm. In this new approach, project-specific cybernetic software management systems are produced by pcynlitx platform. Then, the software system is governed by cybernetic management system which best fits the requirements of the application to be developed. In this project, the software development platforms that produce cybernetic control systems are named as programmable meta-programming systems. You can find out more information about meta-programming and the programmable meta-programming systems on the programming tutorial. The programming tutorial can be available from documentation section. You can read a brief introduction of the project from the links which are given in below.
The cybernetic control of the software systems
On the software systems which are developed with Pcynlitx platform, the decision about the program flows are taken based on the feedback received form both the software itself and the programmer directives. In fact, pcynlitx platform produces cybernetic control objects based on the requirements of the project. Then, the objects which are produced control the program flows cybernetically. They can collect information from the software and can steer the process in line of programmer directives.
The innovation on the multithreading
On the site of multithreading, the innovation is deterministic multithreading. Different from classical single threaded softwares, in multithreaded softwares, multiple flows of execution run concurrently inside a single process . In other words, multithreaded softwares have multiple program flows. At the same time, the threads share the common resources which are allocated to the process. Therefore, the biggest problem on the current multi-thread software development process is managing this chaos.
What is multithreading ?
In fact, the execution order and the priority of the threads reflect the term of scheduling. Unfortunately, on the current systems, the threads are scheduled randomly by the operating system and/or underlying hardware . On the each run of the program, the threads and code sections are executed with different order. This situation breaks down input-output determinisim of the multi-thread applications and thus, developing, debugging and testing multi-thread applications much more difficult. However, with pcynlitx, you can directly determine the execution order of the code fragments independently from the operating system and underlying hardware. By this way, with pcynlitx, developing and testing of a multithread software is much more easy. A typical illustration of this property has been given in below.
In this figure, the code fragment is executed by the threads in an exactly same order on each running of the program. In oder words, the critical section is executed serially and same order on each running of the threads. This property increases the stability, predictability of the software bahavior. However, this property is not the only accomplishment of the cybernetic thread management. With cybernetic thread management, the threads can be pro-actively controlled and the program flows are completely under control of the programmer. You can learn many other spectacular properties of the cybernetic thread management from the documents and tutorials.
INTRODUCTION TO PCYNLITX PROJECT
Pcynlitx is an outcome of a scientific research study that is carried out by Erkam Murat Bozkurt who is a research engineer in Istanbul / Turkey. For more information about the developer of the platform, please look the developer section of the web site. Pcynlitx platform has been developed based on a new idea. This idea is to develop a software that can write codes in a collaboration with its user. By this way, Pcynlitx acts as a separate intelligent actor simplifying the multi-threaded software development process. Basically, pcynlitx is a code generator which can be programmed by the programmer. More specifically, It receives the requirements of the software to be developed from the programmer by means of a descriptor file and then, writes a C++ class library ( a thread library ). In practice, the programmers enter their preferences to the graphical user interface of the pcynlitx by means of some menus and pcynlitx builds the descriptor file automatically.
