I THINK you could accomplish something like this by making your swap file absurdly huge (like 1tb) and then setting your application to use the \tmp or any of the other folders that are technically in RAM in Linux. The only issue is I don’t know if you could tell it to only use the m.2 and it would obviously be somewhat random with where it locates data in the m.2 vs actual RAM. Maybe if you set your swap to a different device and ONLY told it to use that?

I suspect that still probably wouldn’t be exactly what you want. What you actually want is Intel optane.

Have you ever printed anything on Linux before?
