Is Parallel Programming Hard?
Is Parallel Programming Hard, And, If So, What Can You Do About It?


The current version is
v2023.06.11a [PDF]
(single-column format [PDF],
ebook format [PDF],
change log).

The default double-column format is easiest on both the trees and
the eyes in paperback book form.
The single-column format works well on large-format ebook readers.
Smartphones and smaller ebook readers get better results with the
ebook format.


If you would like a dead-tree copy, please feel free to use any
of a number of internet-accessible printing services, or you can find
dead-tree copies of the first edition
here.
If you would like a fancy dead-tree copy, here is some shiny artwork for
front
and
back
covers, courtesy of Melissa Broussard.
The older cover art is still available for those who prefer the classic
look
(front
and
back).

Contributions are welcome, and to that end, a public git tree
may be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/perfbook.git.
This git tree also provides an up-to-date version for those who are too
impatient to wait for the next release.
Those who are also too impatient to set up the LaTeX build environment
can avail themselves of Leonardo Brás's gitlab CI flow for
current PDFs
and also for
older PDFs.

There is an email list
(perfbook@vger.kernel.org,
subscribe here)
for feedback, patches, review, and discussions.
Please see the end of Chapter 1 of the book itself for more information.
