Let There Be Light: The Year in Silicon Photonics
- frozenport 10y agoUnmentioned is the comparable larger wavelength of light. This requires structures that are 500nm rather than 20nm. Silicon photonic for on-chip communication will need to show a 25x performance advantage to reach parity.
- kodfodrasz 10y agoI'm not sure how would photonic memory connection obsolete NUMA. The non-uniform latency problem would still persist possibly at a different magnitude of connected memory.
- xorcist 10y agoThe article only talks about bandwidth. What's latency like? Latency is often the performance bottleneck, and I would guess HPC applications to be even more sensitive.
