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.

Parallel computing using IPython


IPython allows users to perform parallel and high-performance computing in an interactive manner. We can use IPython's built-in support for parallel computing, which consists of four components that make IPython suitable for most types of parallelism. Specifically, IPython supports the following types of parallelism:

  • Single program, multiple data parallelism (SPMD): This is the most common style of parallel programming, and it is a subtype of Multiple Instruction and Multiple Data (MIMD). In this model, each task executes its own copy of the same program. Each task processes different datasets to achieve better performance.

  • Multiple program, multiple data parallelism: In the multiple program, multiple data (MPMD) style, each task executes different programs that process different datasets on each participant computing node.

  • Message passing using MPI: A Message Passing Interface (MPI) is a specification for developers of message passing libraries. It is a...
