That’s actually not the case. Historically, low amounts of RAM and IO were the bottlenecks, we’re talking quad-core arm-v8 with a pretty beefy vector gpu/coprocessor.
True. And with RPi4 having a 1000baseT, it’s not as painful as it seems. Perhaps even the driver can be coaxed into some form of DMA and MPI that is a bit lower latency than IP stack. With secondary IP layer on 802.11,…
There are two ways of doing clusters - one is a message passing paradigm, which you can do over Ethernet (to an extent - I’d still take USB3 for 4x the bandwidth) - and the other is direct memory access a’la Cray. What…
This might even allow some level of memory mapping in all directions. Unfortunately PCIe switches are not very hackable as such, but maybe I can spin a board for this purpose... after I get the hack more industrialized.
Hack’s creator here - it’s on my list of things to try. GPUs are notoriously hard to get to work on non-intel, having tried to get a few up on Alpha and Itaniums in the past. VideoBIOS expects to run and expects a well…
