Query: Exploring the acceleration of the Met Office NERC Cloud model using
  FPGAs   The use of Field Programmable Gate Arrays (FPGAs) to accelerate computational
kernels has the potential to be of great benefit to scientific codes and the
HPC community in general. With the recent developments in FPGA programming
technology, the ability to port kernels is becoming far more accessible.
However, to gain reasonable performance from this technology it is not enough
to simple transfer a code onto the FPGA, instead the algorithm must be
rethought and recast in a data-flow style to suit the target architecture. In
this paper we describe the porting, via HLS, of one of the most computationally
intensive kernels of the Met Office NERC Cloud model (MONC), an atmospheric
model used by climate and weather researchers, onto an FPGA. We describe in
detail the steps taken to adapt the algorithm to make it suitable for the
architecture and the impact this has on kernel performance. Using a PCIe
mounted FPGA with on-board DRAM, we consider the integration on this kernel
within a larger infrastructure and explore the performance characteristics of
our approach in contrast to Intel CPUs that are popular in modern HPC machines,
over problem sizes involving very large grids. The result of this work is an
experience report detailing the challenges faced and lessons learnt in porting
this complex computational kernel to FPGAs, as well as exploring the role that
FPGAs can play and their fundamental limits in accelerating traditional HPC
workloads.
