Tutorial on the OpenCL 2.0 Generic Address Space

February 11, 2015 by Rob Farber Leave a Comment

Adam Lake and  Robert Ioffe posted a nice tutorial on the Intel website about the new OpenCL 2.0 generic address space. The OpenCL 2.0 generic address space makes writing OpenCL programs easier by removing the requirement of decorating all pointers with a points to address space. Instead, OpenCL programmers just use pointers as they would in standard C. Utilizing this new … [Read more...]
