I have updated the Web site’s Sample Chapters section to point to The CUDA Handbook‘s page in Safari Books Online’s Rough Cuts. Rough Cuts gives early access to books while they are still in progress – 3-6 months from publication, and includes tools for readers to give feedback to the author while there’s still time to make changes.
Several chapters are still missing, but they will be uploaded soon.
I’m still interested in reviewers who would be willing to take a look at sample chapters and submit feedback. Write me at firstname.lastname@example.org.
