new memory record for me

[keith smith]

I'm curious.  What type of CPU's are they using.  I must admit I know little about computer architecture and O/S's at this level, however it seems multiple computers would be better than one big one.

What is the advantage to so much RAM in one computer?

What are the advantages of one computer with lots of RAM versus something like a Beowulf cluster?

Last year I spent the summer working at the Intel benchmarking center in Dupont, WA and some of you might recall me posting about some large memory systems there with 256GB of memory. At the time that was the most memory I had personally witnessed running in a Linux server (RH6.1 to be exact). 

Well this month I am at a national weather & climate research lab in Wyoming and that memory record has been broken. Here as part of their latest research cluster purchase they have 17 large memory systems that are used for OpenGL based visualization. These systems have 1TB of main memory! Unfortunately it seems that the latest NVidia Quadro 6000 video cards have only a 39bit register for addressing memory which means there are problems when using them in systems with 512GB or more of memory.
