    Abstract:

Applications: It can be used with any computational hardware that has multiple cores
Advantages: Around 2004, 50 years of exponential improvement in the performance of sequential computers ended. Although, the quantity of transistors on a chip continues to follow Moore'ss law (doubling roughly every two years), it has become increasingly difficult to continue to improve the performance of sequential processors. Instead of increasing the clock speed of processors, more cores are being put on a single chip. This parallel architecture offers a potential solution to the problem of stalled performance growth. The number of processors that can be fabricated on a chip will continue to increase as per the Moore’s law, at least for the next few generations. So, to exploit the parallel architecture, applications need to be parallel programmed, obviously for performance reasons. Unfortunately, parallel programming is far more difficult to design, maintain and debug than sequential programming. Formulating algorithms and proving their correctness is even more difficult. The bugs are non-deterministic and parallel programs often give poor performance. Adding to the woes, reasoning about parallel programs doesn’t come naturally to human mind. Keeping in mind the difficulties associated with traditional synchronization mechanism in parallel programming, alternatives constructs are needed, which removes the burden of all concurrency issues from programmer. Software Transactional Memory (STM) is one such construct. It takes care of all the synchronization difficulties. This product is such a library developed based on such a STM system. It is based on single-version and multi-version timestamp protocols which have been proved to be quite efficient.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
