Curious.
This is somewhat reminiscent of SGI's ccNUMA and CRAYLink/NUMALink architectures.
If memory serves, IRIX (SGI's UNIX OS) had both the metrics to see the latency of access, and the ability to migrate the data and/or the compute closer to each other.
ccNUMA was open-sourced and AMD uses it on their multi-core/multi-socket systems, though usually within the motherboard. Not so much leaving the case and interlinking SGI Origin system style (which is what the CRAYLink/NUMALink tech did).
- MisterTea 7y agoThe sad thing is that Hyper Transport was supposed to offer this exact feature and implement it just like SGI did with NUMAlink. There were a few boards produced with HTX slots, I have an older Tyan dual socket Opteron board with an HTX slot kicking around. There is a connector standard: https://www.hypertransport.org/ht-connectors-and-cables https://www.hypertransport.org/ht-connectors-and-cables Connectors available from Samtec: https://www.samtec.com/standards/ht3#connectors https://www.samtec.com/standards/ht3#connectors Manycore CPU's and converged ethernet pretty much made it moot.
- kjs3 7y agoYeah...HTX was really interesting until it was clear that 40G/100G enet was going to become commodity really fast.
