Partitioned Global Address Space (PGAS) compilers/runtimes do something similar to that. Unified Parallel C (UPC,https://upc.lbl.gov/) and Coarray Fortran/Coarray C++ (https://docs.nersc.gov/development/programming-models/coarra...) are good examples commonly used in HPC. Fabric Attached Memory (OpenFAM, https://openfam.github.io/) is another example.

“commonly used in HPC” is a bit of a stretch if you’re talking about production applications.
