What is single source vs non single source programming?

[Sirgeorge]

I was looking at the various offerings of Khronos and stumbled upon this term that gets referenced in several places but isn't ever explained in any real detail. I THINK I understand? What is "single source" and "non single source" in the context of these parallel languages and APIs? For example, SYCL is described as a "Single source C++ programming with compute acceleration" higher-level language/API. Also, does "non single source" mean multi source? Any help would be appreciate.

Hey Sir George single source programming mean that you can save all of your source code in a single file and non single source is just the opposite.

 

Quote me if it helps.

You did fall onto the subject on Khronos mainly because some of their offering i.e OpenCL is a non-single source (multi-source) however you want to call it.

Like Mark mentioned it really just mean you have either the code in a single file AFTER compile or in 2 or more files for non-single source.

It's not real software terminology and it's just marketing nonsense. It doesn't have a technical definition and even after reading their product page and wiki, I'm still confused about its actual meaning, which I guess is the point.

 

The only references I can find on it are the times SYCL has itself shamelessly added it to things like the OpenCL's wikipedia page when mentioning itself.

 

 

Ah, all of these three things paint a mosaic of understanding. Thank you all!
