Chapter 16. Debugging Parallel Programs
If you
are using a cluster, you are probably dealing with large, relatively
complicated problems. As problem complexity grows, the likelihood of
errors grows as well. In these circumstances, debugging becomes an
increasingly important skill. It is a simple fact of lifeif
you write code, you are going to have to debug it.In this chapter, we'll begin by looking at why
debugging parallel programs can be challenging. Next,
we'll review debugging in general. Finally,
we'll look at how the traditional serial debugging
approaches can be extended to parallel problems. Parallel debugging
is an active research area, so there is a lot to learn.
We'll stick to the basics here. |
