WebTHX. If you have 1 card with 2GB and 2 with 4GB, blender will only use 2GB on each of the cards to render. I was really surprised by this behavior. WebMemory management on a CUDA device is similar to how it is done in CPU programming. You need to allocate memory space on the host, transfer the data to the device using the built-in API, retrieve the data (transfer the data back to the host), and finally free the allocated memory. All of these tasks are done on the host. high waisted pants and bra https://a1fadesbarbershop.com
