Case Study

CARA Supercomputer

The CARA supercomputer provides resources for DLR scientists.

CARA will accelerate the introduction of new technologies for more economical, environmentally friendly, and safer flying. For this purpose, hardware components (AMD processors) were selected that enable optimal use by simulation codes that are developed at DLR. These simulations contain all properties and components of an aircraft based on highly precise physical and mathematical models. They are a prerequisite for the virtual development, testing, operation, and certification of aircraft. In addition, CARA can also be used in space travel and traffic research: for example, in the field of space transportation of the future or for next-generation trains.

CARA operates with a very warm liquid cooling from CoolIT, supplied by temperatures above 46C from the facilities, which reduces the TCO of the Supercomputer.

  • This system offers scientists 1.74 petaflops of computing capacity
  • #221 on the Top 500 Supercomputers in the World (Nov 2019)
  • CARA Supercomputer Liquid Cooling Technology:
    • 28x racks with direct liquid cooled NEC Computing servers
    • 28x Stainless steel Rack Manifolds, featuring 100% dry-break quick disconnect technology
    • 2x row based CDUs managing 28 racks
