POWER9 is interesting (compared to RISC-V) because, right now, you can buy up to a 24 core, SMT4 system (96 threads), running dual CPU sockets if you like, and supporting up to 1 TB of memory per socket, with a maximum boosted clock speed o

The first thing to know is there's a community of people using POWER9 workstations, whether for actual "work" or just as personal computers for, well, personal use. In both cases, web browsers are very important. These device

Unfortunately no, it needs little-endian for both 64 and 32 bit modes, which means that, practically, it's limited to systems with POWER{8,9,10} CPUs, along with a smattering of other (relatively) modern SoCs with LE support. However,

Since it's not immediately clear looking at the repo, and porting it has been a side project of mine, I'll go ahead and add that PowerPC is one of the other non-ARM platforms supported. Both on box64 and box86, although ppcle is s

But RAM is itself accessed in blocks. The process is hidden to software, but memory is always fetched in word-aligned blocks. It doesn't contradict your point, but just pointing out that even DRAM is pulled in chunks not unlike traditi

Just a thought, but one reason to be skeptical of virtual reality, if only out of pragmatism, is that unlike "real" reality, virtual reality is trivially controllable by single entities. Maybe not an intrinsic limitation, but for

I think the response of advocates would be that the solution is for more people to use AGPL, which would fix that "loophole". Now, I don't see AGPL becoming widespread personally, but this is essentially its reason for existi
