R High Performance Programming

Key Features

Book Description

What you will learn

• Benchmark and profile R programs to solve performance bottlenecks
• Understand how CPU, memory, and disk input/output constraints can limit the performance of R programs
• Optimize R code to run faster and use less memory
• Use compiled code in R and other languages such as C to speed up computations
• Harness the power of GPUs for computational speed
• Process data sets that are larger than memory using diskbased memory and chunking
• Tap into the capacity of multiple CPUs using parallel computing
• Leverage the power of advanced database systems and Big Data tools from within R

Who this book is for

This book is for programmers and developers who want to improve the performance of their R programs by making them run faster with large data sets or who are trying to solve a pesky performance problem.
