Or PCIe... I really would like to try building that.
- jiggawatts 2y agoI'm fairly certain you can't create a "mesh" with PCIe between multiple hosts. It's more like USB instead of Ethernet.
- throw4950sh06 2y agoDon't treat the CPU board as the host but a peripheral. ;-) But I'd say it's much closer to Ethernet than USB. You have controllers (routers), switches and nodes... USB doesn't, not like this.
- pezezin 2y agoYou can't with standard PCIe, but you will be able to do it with CXL, although I don't know of any server platform that uses it yet.
