It is known that Windows10 with WDDM2.2 reports less than actual VRAM present. For instance with a GTX-1080-TI having 11GB of memory is being reported as only 9GB of free available. However Microsoft claims that as soon as an application claims more memory, VRAM becomes available, so the entire 11GB of VRAM is actually available to the user.
Just to note that the GTX-1080-TI is the 2nd GPU, there is another low profile GPU that has the monitors attached to it as dedicated for display (Set from NVIDIA control panel)
Now, Matlab reports 9.02GB of available VRAM using the 'gpudevice' command. However, this becomes a hard-limit within Matlab. Meaning I cannot declare a GPU variable larger than the available 9.02GB.
What can be done to use the additional 2GB of actual physical memory that is available on the GPU but not accessible to Matlab. This is a very expensive resource and very useful and would like to use it. Can Matlab not claim the memory from the OS (Windows10) dynamically? I am using Matlab R2017a and system spec is 128GB main memory with 2 Xeon CPUs each with 6 cores running at 2.6GHz.
