| Abstract | Task scheduling on multiprocessor systems is of a great interest since it is a computationally difficult problem due to having the possibility of failing in exploiting the true potential of the multiprocessor system as a result of inappropriate scheduling of available tasks. Static scheduling using genetic algorithms is a very popular approach as of being able to efficiently use the available machines and resources. In this paper, we propose an efficient algorithm, namely, sequence algorithm as a novel extension to a traditional existing generic algorithm to solve the task scheduling problem in multiprocessors systems through minimizing the tasks completion time and maximizing the throughput of the system. To achieve that, our proposed algorithm has its own way to initialize the chromosomes. Moreover, it uses a new systematic method for the crossover operator. In our work, we ignore the communication delay between tasks. To show the effectiveness of the proposed algorithm, we performed experimental simulations to see how far we need to go, for reproducing generations, to obtain acceptable efficiency. Actually, the results show that we can obtain a variance less than 10% (efficiency ≥ 90%) with a small number of iterations. By comparing the proposed algorithm with an existing genetic-based algorithm, it is found that the efficiency of the new algorithm to find a suboptimal schedule is increased for a fixed number of generations which in turn leads to decreasing the length of schedule or the completion time. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
