I installed the latest SDK 9.1 with the included driver AND Visual Studio 13 CE on a Windows 2016 base AMI. I am able to run/debug my CUDA application, but the response to cudaGetDeviceCount is only 2 GPUs available.
There is supposed to be 8 GPUs on a p3.16xlarge instance. Is this a limitation of the current driver for Windows?
I assume that the correct number is reported for a Linux AMI since that seems more widely used. When can I use all the GPUs under Windows?
