However, the network you discussed doesn't fit what most of us have at
home. I'm lucky to get 6Mb up and 1Mb down. I could go with a cable
solution and get 5M and 5M, but that is a bunch of orders of magnitude
below the network you specified the cloud you bench-marked. Moreover,
the partitioning of data to utilize the other processors is not just a
thread cast from most versions of Windows. That has to do with Windows
low level design. It can be tricked into doing that, but there are other
burdens that arise and have to be coded around in one form or another.
And as to what you said about the local OS, I don't know if that is
strictly true or not any more, or at least it certainly doesn't have to
be. When the system has multiple processors, several could be the app
machine and the other the OS, and the partitioning could be fixed or
variable depending on the software design. Of course all the OS
interface to system storage would have to be re-entrant and double
buffered to accomplish that. But in essence I could implement a small
cluster with a file server over a local 100 to 100G Ethernet and get
that end of it sorted. If the server has multiple processors with
individual SATA, and I have separate page swaps or hardware memory
swaps, I have whipped the basic speed limits. As to parallel processing
applications, that still depends on the application casting threads to
utilize the additional processors, but with cloud infrastructure, the
latency of the cloud becomes an issue. If the cloud is local, that is
one color cat, and if the cloud is a central control use, that is
another cat, and if the storage is distributed, another tail to both
cats. More over, why on earth would I pay to run a computer on an
This is simply a smokescreen to add costs to the consumer for big
software and internet companies, and it is being fed via spoonfeeding to
the colleges developing designs. Given equivalent connect speeds, a
local network beats a distance network every time, until someone gets
quantum links working. But if that works, we don't need the wires any
more do we? I don't pretend to know what's coming, but I do know that
when stuff is outside my house it can be priced annually, it can be
arbitrarily withheld, it can be surveiled, it can be compromised by
those who have direct physical access, and it is not something I really
want or need. Just my honest opinion.
