like this. 512 CPUs, 24 TB memory, hundreds of 15,000 RPM disc drives.
Right now. VA. Tech built one...
Ooo... I want one, even though I don't really know what it's for and would only fill up about 30 gigs of it.
When I'm crazy, old, and rich (IN THAT ORDER.) I'll get one.
You look like you're already there.
Just think of the framerates you could get in Half Life 2 on that baby. :drool:
Since Half Life or any game can take advantage of one or two CPUs plus the Intel Itanium 2 is a very poor performer when running 32-Bit Windows Programs. To summarize: terrible frame rates.
The VT one has more that 2200 2.3Ghz processors in more than 1100 xserves. Each Xserve having 4 Gigs of memory.
Except it isn't tightly integrated like a NUMA machine is. Each Xserve can only access it's own local memory and discs. Big iron like this really is different; a 512-cpu NUMA machine is hardly the equivalent of 512 PCs. Individually the PCs may be faster at some things (like integer computation). Considered as a collective they're often a lot slower, especially on I/O (where the PCs get their heads handed to them) and on data sets too large to fit in a mere 4 GB of RAM (note the Altix maxes out at 48 GB per cpu).
