[hpsdr] [dttsp-linux] ATOM update

[Bob McGwier]

I am running all of that on the Atom 330 (D945GCLF2 mobo) with the 
addition of Windows XP64 and it is flawless. I had an XP64 disk that has 
not been installed on a system in two years and it needed an hour to do 
all of the Windows updates which tells you how old it was. Everything 
works flawlessly. The big discovery that Intel made with the multiple 
core technology is that modern operating systems can be single threaded 
and need a huge clock, gobs of power, and hard to build transmission 
lines or they can build many slower cores to run in parallel and then 
have high demand jobs basically get a "CPU to themselves" rather than 
deal with locks of context switching, etc. and overall, be much better off.

It has absolutely revolutionized the computer industry at the consumer 
level and has made seriously capable computers dirt cheap.

This is NOT to say this is one size fits all. I am also building an 
Intel I7 extreme machine where the cost of the motherboard is twice what 
I paid for the entire Atom 330 computer. It is being built so I can 
effectively use Nvidia GPU's (I have a two GPU Telsa and will have two 
more on the graphics card and SLI bound to the Tesla) for DSP 
supercomputer. This is also not for everyone because it will cost $2500 
without the Tesla.

I am extremely happy that Intel brought all of this out and extremely 
grateful to Phil Covington for suggesting this to Frank and I. I am 
happy to have had the time to go through all of the necessary pain to 
get everything going to make it easier for everyone else to follow. I do 
believe we are approaching, and rapidly, the time when an all SDR setups 
will be "comodity priced" and "every man" can afford them and have 
startling capabilities. This is my dream and goal and I thank EVERYONE 
who follows all of this wandering we do because without the interest and 
support of this experimenter and user community, we would not make large 
progress. Whitespace rules and large scale integration and many way SMP 
cores at reduced power and more will push all of us in this direction 
whether we want to go there or not. I am happy we are.
