The programming language Fortran dates back to 1957 when a team of IBM engineers released the first Fortran Compiler. During the past 60 years, the language had been revised and updated several times to incorporate more features to enable writing clean and structured computer programs. The present version is Fortran 2018. Since the dawn of the computer era, there had been a constant demand for a “larger” and “faster” machine. To increase the speed there are three hurdles. The density of the active components on a VLSI chip cannot be increased indefinitely and with the increase of the density heat dissipation becomes a major problem. Finally, the speed of any signal cannot exceed the velocity of the light. However, by using several inexpensive processors in parallel coupled with specialized software and hardware, programmers can achieve computing speed similar to a supercomputer. This book can be used to learn the modern Fortran from the beginning and the technique of developing parallel programs using Fortran. It is for anyone who wants to learn Fortran. Knowledge beyond high school mathematics is not required. There is not another book on the market yet which deals with Fortran 2018 as well as parallel programming.

Sri Ramakrishna ,-Songs and Lyrics offers the glory-garland derived from the grace of Sri Ramakrishna ,that has come upon in the life of a lay-disciple who with ardent anguish ,and widow-tears ,prayed ,and ever prayed for Sri Ramakrishna's grace . The poems included in this book have with them ,the devotional frenzy mantled upon the poet by the graces of the Holy-Trio ,-Sri Ramakrishna , Holy-Mother -Saroda , Swami Vivekananda , and the Spiritual Master of the poet, -Swami Bhuteshananda Ji Maharaj ,-the 12th President of Sri Ramakrishna Order . In the back-ground of each poem , the divine -transcendence of Sri Ramakrishna remains its immortal-live . The readers would certainly explore the beauty-budded-truth of spirituality while they would go through the poems .Human-pilgrimage in this earth is not a passing mirage ,but a passage for realization the hidden divinity .The poems uphold how our approach to Sri Ramakrishna electrifies our inert -mind , and converts the mind into a Super-Conscious mind .
