Scheduling Bounds in Different Software Transactional Memory Implementations. Tightly-Coupled Shared Memory Systems. The study of human behaviour is very complex and complicated concept.. It is affected by the psychological factors such as perception, learning, peronality and motivation.. In addition to these factors, individual behaviour affects and affected by the behaviour of others. . Prof. Smruti R. Sarangi. IIT Delhi. Outline. Multicore Processors. Parallel Programming Pardigms.

Linear Model. In this linear communication model, communication is like giving an injection: a sender encodes ideas and feelings into some sort of message and then conveys them by means of a channel (speech, writing, and so on) into a receiver, who decodes the message..
