Its a cluster .... there are 2 separate systems.

It's probably virtualized, which lets you configure any odd amount of 
memory you want, pretty much.

Correct, 24GB of ram is more usual.
It might infact be a VM of 23GB... 1GB for the barebone.
Or a commercial cover-up, to avoid the issue of Gi/G, or whatever

24740416k is reported in system monitor of gnome as only 23.6GB, go figure.

It *is* virtualised, but if the RAM doesn't physically reside on the 
same system, you're going to see a jaw-droppingly *vast* performance 
drop. (Which would kind of negate the whole point of those multiple CPU 
cores...)

Sure, but the system may well have 128 GB of memory installed in it (for 
example), and only 23 GB allocated to that specific machine - that's my 
point.

I think it has a quad-core 2 hyperthreads per core. At least, according to 
the intel specs, if I read them right.

    C# - a language whose greatest drawback
    is that its best implementation comes
    from a company that doesn't hate Microsoft.

It's an amazon compute server you're renting by the hour. Yes, it's in a VM. :-)

And my point is "where the **** do you get a system that can handle more 
than 16GB of RAM from?!"

From computer stores, where else? However, 16 is an odd number in days of
tripple channel. Consumer/prosumer mb's typically will top out at 24GB
(single cpu) or 48GB (dual cpu).

Most if not all the motherboards I've seen top out at 8GB, actually...
