The memory bandwidth on the XEONS is quite restrictive for many types of
calculations,
plus the overall power consumption on large memory

whats the temperature that somethign thsi big generates and what is used to
cool it. also why opterons wouldnt there be a better performance gain from
the new 45nm quad core intel's with 12mb cache?

Top500 says it's measured at 2.3 megawatts.

IANS, the triblade is really a quadblade, blade 1 is the Opteron Blade,

Dear all:
Thanks for all the responses. I was at the Roadrunner booth
at SC07. They had a handout explaining the Roadrunner
architecture which also has a picture of racks of blades

Hi all:
I am sure most people have seen the following picture for Roadrunner
circulating the Net:

However, they don't look likes blades to me, more like 2U IBM x series
servers. Perhaps those are the I/O nodes?

Bernard,
I'm looking forward to hearing from our resident experts, but
meanwhile: http://en.wikipedia.org/wiki/IBM_Roadrunner exlains the
architecture some. The buzzword is triblade, which is 3 blades (with an
extension) employing two types of processors (AMD Opteron and IBM Cell) in

All,
Not a expert, but I know a thing or two. The triblade is two CB2 blades
which each hold each two PowerXCell processors in a cc-NUMA arrangement.
They sandwch a LS21 blade that is connected to each through a 16x PCIe to HT
bridge. These three are uni-body constructed. The CB2s resemble the
