RaDex:

rhapsody.backends.data can be used inside Radical Data Exchanger RaDex. The RaDex imports — Endpoint.serialize() to use it for moving scalars and tensors between the heterogeneous components of an HPC-AI workflow — MPI simulations and Python functions without going through a filesystem and what you build from it is entirely up to you.

The examples directory has both styles side by side: 00/01 use RaDex's typed clients, 02/03 use plain redis-py/native dragon.data.ddict.DDict — same infrastructure, different client.

OpenFoam via RaDex:

The RHAPSODY OpenFOAM plugin lets you define and run OpenFOAM cases as RHAPSODY workflows. For more information please visit the main repo to setup and run the plugin here radex-openfoam-plugin
