Troubleshooting in Parallel

The R programming language is a crucial component of the modern tech stack, but R code can sometimes take time to execute. This course on parallel programming can help you optimize your code by leveraging the multiple processors found in most modern computers. You'll grasp key parallel programming concepts and identify operations that can benefit from parallelization. You'll also explore established R packages (parallel, foreach, future) for parallelization and acquire the skills to reduce execution time, monitor, debug, and ensure reproducibility in parallelized code.

<h2>Speed Up Your Code with Parallel Programming</h2>
<br><br>
R programming language is a key part of the modern tech stack. But sometimes, R code takes a long time to run. The good news is that most modern computers have multiple processors. This course on parallel programming can help you speed up your code by harnessing the hardware you already have.
<br><br>
<h2>Learn the Key Concepts</h2>
<br><br>
In this course, you will systematically learn the key concepts of parallel programming. You will profile and benchmark common computations like bootstraps and function mappings. You will also learn to identify operations that can benefit from parallelization.
<br><br>
<h2>Use R Packages to Parrallelize Operations</h2>
<br><br>
As you progress, you’ll explore a suite of mature R packages (parallel, foreach, future). You will learn to use these packages to parallelize operations with lists, matrices, and data frames. Working through a variety of tasks, you will gain the skills to rein in the execution time of nested for loops. You will also learn how to monitor, debug, and resolve reproducibility issues of parallelized code.
<br><br>
<h2>Parallelize Your Existing Code</h2>
<br><br>
With these tools under your belt, you will be able to write parallelized code that runs significantly faster. By the time you finish, you’ll have the skills to parallelize and maintain existing code in a principled manner.
