byteLAKE's and Xilinx's presentation from the Fifth International Workshop on Heterogeneous High-performance Reconfigurable Computing (H2RC'19).
The workshop was held in conjunction with:
SC19: The International Conference for High Performance Computing, Networking, Storage and Analysis.
Workshop: CFD Acceleration with FPGA
Abstract: Learn more about byteLAKE's CFD Suite (BCS), a collection of Alveo (FPGA) optimized CFD workloads.
announcing today with first microservices: Advection and Thomas Algorithm (linear algebra module). Presenters will explain technical details, followed by in-depth technical discussion with a demo at Xilinx booth.

Foot note:
This is the presentation about the non-AI version of byteLAKE's CFD kernels, highly optimized for Alveo FPGA. Based on this research project and many others in the CFD space, we decided to shift the course of the CFD Suite product development and leverage AI to accelerate computations and enable new possibilities. Instead of adapting CFD solvers to accelerators, we use AI and work on a cross-platform solution. More on the latest: www.byteLAKE.com/en/CFDSuite.

Update for 2020: byteLAKE is currently developing CFD Suite as AI for CFD Suite, a collection of AI/ Artificial Intelligence Models to accelerate and enable new features for CFD simulations. It is a cross-platform solution (not only for FPGAs). More: www.byteLAKE.com/en/CFDSuite.

2. FPGAs – The Ultimate Parallel Processing Device
› No predefined instruction set or underlying architecture
› Developer customizes the architecture to his needs
» Custom datapaths
» Custom bit-width
» Custom memory hierarchies
› Excels at all types of parallelism
» Deeply pipelined (e.g. Video codecs)
» Bit manipulations (e.g. AES, SHA)
» Wide datapath (e.g. DNN)
» Custom memory hierarchy (e.g: Data analytics)
› Adapts to evolving algorithms and workload needs
4. Using C, C++ or OpenCL to Program FPGAs
› Xilinx pioneered C to FPGA compilation technology (aka “HLS”) in 2011
› Enables “Software Programmability” of FPGAs
› Includes open source collection of optimized HLS libraries

6. Agenda
CFD,
Computational
Fluid Dynamics
› Numerical analysis and algorithms
to solve fluid flows problems.
› Model fluids density, velocity,
pressure, temperature, and
chemical concentrations in relation
to time and space.
› Typical applications: weather
simulations, aerodynamic
characteristics modelling and
optimization, flow around buildings
simulations etc.

7. Architecture
› The compute domain is divided
into 4 sub-domains
› Host sends data to the FPGA
global memory
› Host calls kernel to execute it on
FPGA (kernel is called many times)
› Each kernel call represents
a single time step
› FPGA sends the output array
back to host
11. First Microservices Launching Today
› Advection
› Thomas Algorithm (linear algebra module)
› Low barrier entry
» Scalable on demand
» As a Service / Cloud
» On-premise
