Efficiency Gains of Optical Interconnects at Exascale (nextplatform.com)

GPU/accelerated computing, photonics, non-volatile memory...

What an exciting (and disruptive) time for HPC.

Fascinating. A lot of the on-chip photonics stuff has the potential to make huge impacts on other research areas, too - but the potential for significant architectural changes in HPC and even hypervisor workloads with improvements to in-machine/cross-machine buses is huge.
