- Kon-Peki 3y agoThat's an interesting idea. But do you actually need to go all the way to making the extra memory appear as a contiguous part of the system memory? I am thinking about CUDA unified memory and perhaps some parallels to your idea. The number of applications that are likely to use the extra memory is probably pretty small. So if you have some sort of framework that those developers can integrate into their software, you've probably done everything you need to do.
