Affinity

Thread Affinity

Overview

Implement CPU affinity to support binding of render and network threads to CPU cores close to their respective devices (see https://github.com/Eyescale/Equalizer/issues/57). The following threads are affected by the affinity hint:

• pipe hint: binds pipe render thread, AUTO uses all cores close to the GPU
• server/node: binds receiver, command, transmit and main threads, AUTO binds to all cores close to the first NIC used in a listener device
