Topicbox-Message-UUID: e6d9faf4-ead3-11e9-9d60-3106f5b1d025 // Not just inexpensive, but also better aligned with how // they use compute resources (virtual vs. physical threads) // and memory resources. Hrm. I know about the memory/cache issues, but it sounds like there's more on the CPU side I don't know much about. Is there more here beyond the memory question and prediction/pipelining? I'm reading the PDF you referenced now. // Speaking of which -- is SPARC port of Plan9 still alive? Not really. There's a partially-working sparc64 port out there which ran on the Ultra 1 (I think), but it's neither been kept up to date nor made to run on anything beyond that. A few folks (including myself) have poked at it a bit with varying results, none of which were particularly good. Something on Batoka would provide better motivation than my old Ultra 5, though!
