Ron - Re: " Cool, then Linux could run totally in cache!"

This will come to pass with Intel's Cascades chip - due in late 1999, about a year from now.

Of course, DATA caches are important as well as instruction caches.

The Cascades is only one such chip that Intel is working on that will utilize these "Monster" caches.

By the way, a 2 MegaByte cache utilizes about 101 Million Transistors - just for the cache !

Intel's wafer fab processing refinements and yield enhancement programs - and an aggressive management policy - has given Intel's engineers a new go-ahead to maximize CPU/system performance with very little regard for chip size. Except, of course, maximum reticle size restrictions and potential ASPs of these new chips.

Don't be suprised if servers with 2M chips comes with Gig's of memory. It is not just the kernel but application data we are dealing with: Database indices, internet caching. These can't possibly fit in the L2.
