Our laboratory is studying mathematical modeling and the computations using supercomputers and PC clusters. Especially, we study multi-physics computational fluid dynamics(CFD) and we are now developing ”Numerical Turbine”: CFD code for simulating whole flow fields in gas- and steam-turbines and “Supercritical-fluids Simulator(SFS)”: a flow simulator which can be applied to arbitrary substances in gas, liquid and solid states with the phase changes. Both developments are conducted as collaborative researches with companies and universities.

  Present general-purpose supercomputers with microprocessors have insufficient utilization of their arithmetic units, achieving only a fraction of their peak performance. To address this problem, we are researching custom computing machines with reconfigurable devices, such as FPGAs. We are developing at low-power and highly-scalable supercomputing systems based on a tightly-coupled FPGA cluster where FPGAs are connected by an accelerator domain network (ADN) for low latency communication. We study appropriate architecture of arithmetic circuits and memory systems for individual computing algorithm. For more detail, please visit http://www.caero.mech.tohoku.ac.jp.
