Prospects for CFD on petaflops systems. DE Keyes, DK Kaushik, BF Smith. Parallel Solution of Partial Differential Equations, , Software design of SHARP.   For the first time, every entry in this year's TOP list delivers petaflop-level capabilities, with the lowest ranking system coming in at petaflops. The top two supercomputers in the world, known as Summit (housed at Oak Ridge National Laboratory) and Sierra (housed at Lawrence Livermore National Laboratory), have reached performance.

CFD and the wind tunnel experiment will go along side by side. We need to use CFD for the tasks that are too difficult for the experiments. That is the key issue for the future prospect of CFD.

Conclusions. Historical perspectives of CFD in aerospace in the last 30 years were given. Demands for CFD in the Age of Petaflops-scale computing As discussed before, the improvement rate of computer performance is nearly times in 10 years. It is, however, doubtful for unstructured-mesh CFD to fully utilize the expected high performance of near-future computers as mentioned in the previous section.

At first glance, it looks disappointing, but it indicates that CFD technology has developed to a certain level and people use CFD as one of the essential analysis tools even with the PROGRESS AND FUTURE PROSPECTS OF CFD IN AEROSP: OBSERVATIONS FROM 30 YEARS RESEARCH ACE Kozo Fujii* *Institute of Space and Astronautical Science (ISAS).

FLOPS can be recorded in different measures of precision, for example, the TOP supercomputer list ranks computers by 64 bit (double-precision floating-point format) operations per second, abbreviated to FP Similar measures are available for bit (FP32) and bit] (FP16) operations.
