Fujitsu deploys liquid immersion cooling-based x86 cluster

Will contribute to manufacture of safer automobiles through use of simulations to analyze automotive collisions.


Fujitsu has provided the Japan Automobile Research Institute (JARI) with an x86 cluster that uses a liquid immersion cooling system, as a new computational system to simulate automobile collisions. Operations have commenced in October 2017.

The cluster system consists of Fujitsu Server PRIMERGY CX2550 M2 x86 servers in PRIMERGY CX400 M1 chassis, as well as a PRIMERGY RX2530 M2 as a management server. The system is cooled by applying a Fujitsu-developed liquid immersion cooling system, in which the servers are directly immersed in a non-conductive fluid with high thermal transport capacity.

This system runs software such as Fujitsu Technical Computing Solution LS-DYNA, which performs nonlinear structural dynamic analysis(1), currently in use at JARI, and is being used to develop exceptionally elaborate and realistic models of the human body, enabling the simulation of large-scale collisions at greater levels of energy saving. JARI will provide simulation results and the human body models developed using this system to the automobile industry to promote the manufacture of safer automobiles.
