There are appear to be two natural ways to use optical connections for HPCC
|
|
Firstly to support the National Information Infrastructure -- a closely connected set of computers
|
|
Secondly to implement communication on a closely coupled MPP
|
|
These are the national metacomputer versus local computer versions of "same" concept
|
In this presentation we point out that regarding software as a commodity just as hardware suggests that we should build software for NII and closely coupled MPP's from same basic commodity parts --
-
for software this implies use of Web Technology
-
for hardware this says use RISC chips for CPUs but
-
there is not consensus that should same ATM optical interconnects for MPP's and NII
