Implementation of Improved Synchronization in Inter Process Communication using Threads for Microkernel and Distributed Operating Systems

Interprocess Communication (IPC) is used by the cooperating processes for communication and synchronization. With the advent of Distributed Systems and Microkernel Operating systems, IPC has been used for designing the system for cooperation. This raised the requirements for improving the communication and synchronization for the better performance of the system. Here, a mechanism of synchronization between the processes to reduce the waiting time of process using POSIX (Portable Operating System Interface) threads has been proposed to perform and synchronize the given task.

O2: A Network Protocol for Music Systems

O2 is a communication protocol for music systems that extends and interoperates with the popular Open Sound Control (OSC) protocol. Many computer musicians routinely deal with problems of interconnection, unreliable message delivery, and clock synchronization. O2 solves these problems, offering named services, automatic network address discovery, clock synchronization, and a reliable message delivery option, as well as interoperability with existing OSC libraries and applications. Aside from these new features, O2 owes much of its design to OSC, making it easy to migrate existing OSC applications to O2 or for developers familiar with OSC to begin using O2. O2 addresses the problems of interprocess communication within distributed music applications.

Seamless interactive language interfacing between R and Stata

In this article, I propose a new approach to language interfacing for statistical software by allowing automatic interprocess communication between R and Stata. I advocate interactive language interfacing in statistical software by automatizing data communication. I introduce the rcall package and provide examples of how the R language can be used interactively within Stata or embedded into Stata programs using the proposed approach to interfacing. Moreover, I discuss the pros and cons of object synchronization in language interfacing.
