Confusing description of work-item functions (p. 150) #23

Open GoogleCodeExporter opened 8 years ago

Is this errata for the book or an issue with the source code? Errata

If errata, please describe the problem in the book (with page number). If
this is an issue with the source code, please specify the problem,
platform, OpenCL implementation, and any additional information that will
help us reproduce the problem:

Under Work-Item Functions on page 150, it is stated that OpenCL does not 
describe how global and local IDs map to work-items and work-groups and that 
nothing can be assumed of these.  However, such a mapping is given in chapter 
1, on pages 14-16.  This mapping is described in the same way in section 3.2 of 
the OpenCL specification.

Maybe it should be something like:

"OpenCL does not decribe how the global and local IDs map to processing 
elements and compute units. ..."
