Learn HPC computing
About the Book
This book has been specially designed to enable you to utilize parallel and distributed programming and computing resources to accelerate the solution of a complex problem with the help of HPC systems and Supercomputers. You can then use your knowledge in Machine learning, Deep learning, Data Sciences, Big data and so on.
Interactive version available @ Scientific Programming School
