MultiExcerptNamePre-populating the GPU cache

The very first time you render with the GPU, the GPU renderer has to create a cache for the types of shaders and objects used. This can delay the time to the first pixel for your first render. To avoid these one-time delays, we recommend doing some of this in advance by pre-populating the cache before you do any renders as this will fill in the cache with a subset of the most common shader/object combinations. The Arnold plugins (like MtoA) have Pre-Populate populate GPU Cache menu command, and kick has a -gpu_warm flag. Note that pre-populating the cache can take up to 15 minutes. The cache only needs to be re-populated after installing a new Arnold version, updating to a new NVIDIA driver, or changing the hardware configuration of GPUs on the system.


The GPU cache is based on the Arnold core version, NVIDIA driver version, and GPU(s) the software is executed on. So  So if one of them changes then you will need to run the to run the Pre-populate Cache again, to avoid delays during rendering.
