[hpsdr] [OT] mITX computing was: Sasquatch II

[Ken N9VV]

I am running an Intel D201GLY from LogicSupply. It is a simple Intel 
Celeron 1.3Ghz processor with one lonely core :-) and 512MB RAM.

It compiles Qt/C++ applications beautifully. I have even built Qt from 
source (5+ hours) and it works perfectly.

I am writing this email from the WinXP/SP3 boot of the mITX. I have it 
dual booted with Ubuntulite.

For Floating Point intensive apps, I can point to SDRMAX-II and 
QS1RServer which contains SharpDSP2.0 when receiving with the 
QuickSIlver QS1Rb.  It seems to load the processor to about 30% and I 
still get excellent USB 2.0 throughput and extensive Internet UDP 
traffic on my LAN at about 2Mbps. All the Video in the GUI is quite 
good, even with the crummy SiS mobo chip.

I am able to run OpenGL 1.2 compliant applications just fine. An example 
is the current exploration that Cathy Moss in the UK is making with 
SDRMAX-III GUI built from Qt/C++ and OpenGL code.

Now, you fellas with the multi-core models (I am jealous) can run 
concurrent (parallel) 'make' with these commands in Linux:
export CONCURRENCY_LEVEL=3
(one greater than number of cores)
make -j3
(also one more than number of cores)
and that will scream along and compile Qt from source in less than an 
hour :-)
