Overview of this book

In today's world, along with theoretical and experimental work, scientific computing has become an important part of scientific disciplines. Numerical calculations, simulations and computer modeling in this day and age form the vast majority of both experimental and theoretical papers. In the scientific method, replication and reproducibility are two important contributing factors. A complete and concrete scientific result should be reproducible and replicable. Python is suitable for scientific computing. A large community of users, plenty of help and documentation, a large collection of scientific libraries and environments, great performance, and good support makes Python a great choice for scientific computing. At present Python is among the top choices for developing scientific workflow and the book targets existing Python developers to master this domain using Python. The main things to learn in the book are the concept of scientific workflow, managing scientific workflow data and performing computation on this data using Python. The book discusses NumPy, SciPy, SymPy, matplotlib, Pandas and IPython with several example programs.

Advanced features of IPython


In subsequent subsections, we will have discussions of the various advanced features of IPython.

Fault-tolerant execution

The IPython task interface prepares the engines as fault-tolerant and dynamic-load-balanced cluster systems. In the task interface, the user does not have access to the engine. Instead, task allocation completely depends on the scheduler, and this makes the design of the interface simple, flexible, and powerful.

If a task fails in IPython, for any reason, then the task will be requeued and its execution will be attempted again. A user can configure the system to take a predefined number of retries if there is a failure, and they can also resubmit the task.

If required, users can explicitly resubmit any task. Alternatively, they can set a flag to retry the task for a predefined number of times—by setting a flag of the view or scheduler.

If the user is sure that the cause of the error is not a bug or problem in the code, then they can set the retries...
