Yes - so if you put 1000 cores with 1000 caches on a chip you could run 1000 vm's - more or less, perhaps 10000 in fact? Why aren't there chips like this... I think because it would blow apart the server manufacturers business models, and Intel's business model as well.
- eesmith 7y agoThose caches take up space. Or rather, if you could have 1000 cores each with 16 MiB L3 on-die cache, then why don't we see machines now with 10 cores and 1.6 GiB on-die L3 cache? After all, there already exists plenty of software (including some I wrote) which is limited by memory bandwidth, or by latency. Also, all of those 1000 cores would compete for the same main-memory bandwidth, so are much more likely to be bandwidth starved.
