"IDT Voltage Regulator Modules Power The World's Fastest Supercomputer"
 September 14, 2010
  http://www.idt.com/?id=5751

  "Altix UV utilizes the IDT Power VRMs for microprocessor, ASIC and
   memory power requirements."

  "The VRMs selected by SGI utilize the IDT-patented coupled inductor
   technology to improve performance and reduce power consumption in
   computing applications."

  "Each Altix UV server blade uses nine high-density IDT VRMs to
   deliver fast transient response, tight regulation, high efficiency,
   and reliability."



Altix UVは良いマシンだと思いますが、World's Fastestではありません。
安定した大規模システムの実現には、こういう点での十分な気配りが必要ですね。
