Realtionship between EU and shader?

PCox — Fri, 21 Jun 2013 04:44:07 GMT

I'm coming from a CUDA background, and want to wrap my mind around the different graphics terminology in Intel chips. On NVidia harware, groups of threads (each in a core) are scheduled to run on one of a small number of streaming multiprocessors. Is there a similar relationship between EU (=SM) and shader (=core)?

Hello SydneyPhil,

At this point the information is not handy for me but let me research and I will be right back with you as soon as possible.

You can refer to this URL for information:

https://01.org/linuxgraphics/sites/default/files/documentation/ivb_ihd_os_vol1_part1.pdf https://01.org/linuxgraphics/sites/default/files/documentation/ivb_ihd_os_vol1_part1.pdf

Check on page 15 and page 18, they contain information on the EU's. Basically an EU is a sub-section of the processor that splits process information using an even further sub-section of "threads". The listed information on page 18 states that an Ivy Bridge processor can have 16 EU's on it, each with 8 threads of their own for processing/sub-processing.
