Extensions
Some vendors provide extended functionality over the standard OpenCL specification via the means of extensions. These are still specified by Khronos but provided by vendors within their SDKs. They often contain features that are to be implemented in the future - for example device fission functionality was originally an extension but is now provided as part of the 1.2 specification.
Extensions provided in the 1.2 specification include:
- Writing to 3D image memory objects
- Half-precision floating-point format
- Sharing memory objects with OpenGL
- Creating event objects from GL sync objects
- Sharing memory objects with Direct3D 10
- DX9 media Surface Sharing
- Sharing Memory Objects with Direct3D 11

Famous quotes containing the word extensions:
“If we focus exclusively on teaching our children to read, write, spell, and count in their first years of life, we turn our homes into extensions of school and turn bringing up a child into an exercise in curriculum development. We should be parents first and teachers of academic skills second.”
—Neil Kurshan (20th century)
“The psychological umbilical cord is more difficult to cut than the real one. We experience our children as extensions of ourselves, and we feel as though their behavior is an expression of something within us...instead of an expression of something in them. We see in our children our own reflection, and when we don’t like what we see, we feel angry at the reflection.”
—Elaine Heffner (20th century)
