“…NIO [8][9] [10] is an alternative to I/O API of java and has concept of buffers, channels, selectors and asynchronous I/O. a) Buffers and Channels: Java IO is stream oriented that allows to read one or more byte at a time and doesn't allow to move back and fourth in the data stream because data is not cached anywhere.…”

Push technology has evolved to a great extent since its inception and there have been many additions of new features to the available solutions, in terms of reliability, performance and new standards. In this paper, we propose an application to push data in real time which enables bidirectional flow of data and which is independent of any particular publisher/subscriber. The aim of this work is to develop a push server application for students/faculty for accessing study material, to keep track of last minute notices, and other important announcements, in real time from a central file/data server of the university. Usually, the file systems are heavily guarded by firewalls and accessing them from a remote location poses problems, our application solves this problem and allows secure access while maintaining the integrity with university policies. Server application is called PushNotify which is based on publish/subscribe model and is independent, which enables it to be easily integrated with any file server of any university and with any communication client, to achieve the paradigm, "any publisher, any subscriber". Communication client for subscribers to receive notifications or alerts can be web browser extension or mobile device application.

“…In [20], the MPJ Express shared memory device was found to be the main bottleneck in the development of a hybrid shared/distributed memory communication middleware. Furthermore, F-MPJ also outperforms MPJ Express for collective operations as it includes a scalable collectives library tuned for multi-core systems [21] which takes advantage of the reduced overhead of shared memory smdev transfers.…”

This paper presents smdev, a shared memory communication middleware for multi-core systems. smdev provides a simple and powerful messaging API that is able to exploit the underlying multi-core architecture replacing inter-process and network-based communications by threads and shared memory transfers. The performance evaluation of smdev on several multi-core systems has shown noticeable improvements compared to other Java shared memory solutions, reaching and even overcoming the performance of natively compiled libraries. Thus, smdev has obtained start-up latencies around 0.76 µs and almost 90 Gbps bandwidth for point-to-point communications, as well as high performance and scalability both for collective operations and representative messaging kernels. This fact has motivated the integration of smdev in F-MPJ, our message-passing implementation in Java.
