4.85 PiB of RAM -- WOW
- jasonwatkinspdx 5y agoOh that machine is a monster. All the memory is HBM2 as well. So it's stacked in the same package as each processor chip, connected with an interposer. HBM gives you 4 stacks, each with 8 single duplex 128 bit memory buses, that can run at 2+ ghz. So that 4.85 PiB is accessible with a raw bandwidth of around 144 PiB/sec. Definitely a monster of a machine.
- hajile 5y agoThey are at the edge of current RAM limits of 52-bits (I believe this is the case on both x86 and ARM systems). If they could get a system with the full 64-bits of addressable RAM, they'd likely have gone even bigger.
