Query: A TensorFlow Simulation Framework for Scientific Computing of Fluid
  Flows on Tensor Processing Units   A computational fluid dynamics (CFD) simulation framework for fluid-flow
prediction is developed on the Tensor Processing Unit (TPU) platform. The TPU
architecture is featured with accelerated dense matrix multiplication, large
high bandwidth memory, and a fast inter-chip interconnect, making it attractive
for high-performance scientific computing. The CFD framework solves the
variable-density Navier-Stokes equation using a low-Mach approximation, and the
governing equations are discretized by a finite-difference method on a
collocated structured mesh. It uses the graph-based TensorFlow as the
programming paradigm. The accuracy and performance of this framework is studied
both numerically and analytically, specifically focusing on effects of
TPU-native single precision floating point arithmetic. The algorithm and
implementation are validated with canonical 2D and 3D Taylor-Green vortex
simulations. To demonstrate the capability for simulating turbulent flows,
simulations are conducted for two configurations, namely decaying homogeneous
isotropic turbulence and a turbulent planar jet. Both simulations show good
statistical agreement with reference solutions. The performance analysis shows
a linear weak scaling and a superlinear strong scaling up to a full TPU v3 pod
with 2048 cores.
