Hi. I’m writing code that must be able to work on both iGPU and GPU. To make it clear, I’m not trying to use them simultaneously. For iGPU I create a single buffer in host memory, do some computation on host (reading and writing to that buffer using mapped pointer) and then just pass that buffer in…

I tested the code that I wrote for iGPU on Nvidia GPU and performance doesn’t look awful as I expect it to be if buffers were sent from RAM to GPU on every kernel enqueue. I still not sure if it is the optimal approach, because Nvidia guide suggests to create separate buffer for RAM and GPU memory a…

How to efficiently manage memory for both iGPU and GPU?
