Benchmark of Singular Value Decomposition (SVD)¶

Overview¶

This is a benchmark of Singular Value Decomposition. It supports software and hardware emulation as well as running the hardware accelerator on the Alveo U250.

This example resides in L1/benchmarks/SVD directory. The tutorial provides a step-by-step guide that covers commands for build and runging kernel.

Executable Usage¶

Work Directory(Step 1)

The steps for library download and environment setup can be found in Vitis Quantitative_Finance Library. For getting the design,

cd L1/benchmarks/SVD

Build kernel(Step 2)

Run the following make command to build your XCLBIN and host binary targeting a specific device. Please be noticed that this process will take a long time, maybe couple of hours.

source /opt/xilinx/Vitis/2021.1/settings64.sh
source /opt/xilinx/xrt/setenv.sh
export DEVICE=/opt/xilinx/platforms/xilinx_u250_xdma_201830_2/xilinx_u250_xdma_201830_2.xpfm
export TARGET=hw
make run

Run kernel(Step 3)

To get the benchmark results, please run the following command.

./build_dir.hw.xilinx_u250_xdma_201830_2/host.exe -xclbin build_dir.hw.xilinx_u250_xdma_201830_2/kernel_svd_0.xclbin

Input Arguments:

Usage: test.exe    -[-xclbin -rep]
       -xclbin     MCEuropeanEngine binary;

Example output(Step 4)

Profiling¶

The timing performance of the 4x4 SVD is shown in the table below, where matrix size is 4 x 4, and FPGA frequency is 300MHz.

Table 30 Timing_Performance¶
Platform	Execution time
Platform	cold run	warm run
MKL Intel(R) Xeon(R) E5-2690 v3	N/A	8 us
FinTech on U250	196 us	22 us
Accelaration Ratio	N/A	0.36X

The hardware resources are listed in the following table (vivado 18.3 report without platform).
