48 Core Vega 2 in the Making

TobyKY76 writes to tell us The Inquirer is reporting that upstart Azul Systems is planning to integrate 48 cores on their next generation chip. From the article: "The first-generation Vega processor it designed has 24 cores but the firm expects to double that level of integration in systems generally available next year with the Vega 2, built on TSMC's 90nm process and squeezing in 812 million transistors. The progress means that Azul's Compute Appliances will offer up to 768-way symmetric multiprocessing."

So what's the memory model?

So what does the memory interconnect look like on this thing? They say its not NUMA but I see no mention of what it is.

There's no way you can feed that many processors over a single bus and if you've got symmetric access to a bunch of busses, that's one heck of a cross bar switch and I don't see that its any easier to program than NUMA. Instead of making sure data you need fast is local you have to make sure you load balance - that has to be harder much of the time.
