You remember AMD’s OpenCL University Kit? It was for universities and completely written in PPTX. (For people who are on university: PPTX is a undocumented document-form which claims to be open and actually works well with an editor/viewer of only one vendor). So I took the freedom to convert all documents to ODF, so anybody can open them.
Download it here: AMD OpenCL University Kit as ODF.
It has 13 chapters, covering all the basics you need to know for further study. Say “thanks AMD” and enjoy!
