Fabric-Centric Computing

Emerging memory fabrics and the resulting composable infrastructures have fundamentally challenged our conventional wisdom on how to build efficient rack/cluster-scale systems atop. This position paper proposes a new computing paradigm-called Fabric-Centric Computing (FCC)-that views the memory fabric as a first-class citizen to instantiate, orchestrate, and reclaim computations over composable infrastructures. We describe its design principles, report our early experiences, and discuss a new intermediate system stack proposal that harnesses the uniqueness of this cluster interconnect and realizes the vision of FCC.
