Introduction to Parallel Programming

Introduction to Parallel Programming. Instructor: Prof. Yogish Sabharwal, Department of Computer Science and Engineering, IIT Delhi. This course focuses on the shared memory programming paradigm. It covers concepts and programming principles involved in developing scalable parallel applications. Assignments focus on writing scalable programs for multi-core architectures using OpenMP and C. This is an introductory course in shared memory parallel programming suitable for computer science as well as non-computer science students working on parallel/HPC applications and interested in parallel programming.
