The software: LUMA
One programming model across photonic switching and compute
LUMA — the Light Unified Matrix Architecture — is the software layer above LightScale's photonic hardware. A single API spans the Scale1 switching fabric and Photon1 compute: developers write to LUMA, not to individual devices.
Topology, routing, and link assignment are exposed to software and reconfigured at packet cadence. The same code targets every generation, from Scale1 onward, with no per-device rewrite.
