Developer Guide for Intel® SDK for OpenCL™ Applications
Intel® SDK for OpenCL™ Applications standalone version supports user-defined structs. To use structs for kernel analysis, you need to define them:
After defining the struct, you can select is as type when creating a buffer variable:
A CSV file for a struct buffer should have the following format:
For example:
typedef struct Point { int x; int y; float value; }
For a buffer of size 4, the CSV file contains:
0,1,3.56 1,1,33.7 1,0,12.58 0,0,4.85 .
Zero and random values are available as with regular-type buffers.
You can edit a struct. In such case any buffer using the struct reinitializes with the new data.
You can delete a struct as long as other structures or buffer variables do not use it.
When working with uniform variables, fill the values in the pop-up dialog for every field to insert values for the struct. For example:
You must define structs with the same names as used in the code to enable the Kernel Builder to assign a variable to the argument.
