Benchmark Test Overview
Here are benchmarks of the Vitis BLAS library using the Vitis environment and comparing with Intel Math Kernel Library. It supports hardware emulation as well as running hardware accelerators on the Alveo U250.
1.1 Prerequisites
1.1.1 Vitis BLAS Library
- Alveo U250 installed and configured as per https://www.xilinx.com/products/boards-and-kits/alveo/u250.html#gettingStarted (when running hardware)
- Xilinx runtime (XRT) installed
- Xilinx Vitis 2022.2 installed and configured
1.1.2 Interl MK Library
- Downloaded and installed MKL from https://software.intel.com/en-us/mkl/choose-download/linux
1.2 Benchmark with CPU
1.2.1 Step 1 :
Setup and build envrionment using MKL scripts:
source <INTEL_MKL_INSTALL_DIR>/bin/mklvars.sh intel64
1.2.2 Step 2 :
Run Makefile command. For example:
cd gemm_mkl ./run_gemm_mkl.sh 16 float b
1.3 Building and run the kernel with Vitis
Taken gemm/memKernel as an example to indicate how to build the application and kernel with the command line Makefile flow.
1.3.1 Download code
These blas benchmarks can be downloaded from [vitis libraries](https://github.com/Xilinx/Vitis_Libraries.git) main branch.
git clone https://github.com/Xilinx/Vitis_Libraries.git cd Vitis_Libraries git checkout main cd blas
1.3.2 Setup environment
Setup and build envrionment using the Vitis and XRT scripts:
source <install path>/Vitis/2022.2/settings64.sh source /opt/xilinx/xrt/setup.sh
1.3.3 Build and run the kernel
Run Makefile command. For example:
make run TARGET=hw PLATFORM_REPO_PATHS=/opt/xilinx/platforms PLATFORM=xilinx_u250_xdma_201830_2
The Makefile supports various build target including hw emulation and hardware (hw_emu, hw)
The host application could be run manually using the following pattern:
<host application> <xclbin> <argv>
For example:
build_dir.hw.xilinx_u250_xdma_201830_2/host.exe build_dir.hw.xilinx_u250_xdma_201830_2/blas.xclbin build_dir.hw.xilinx_u250_xdma_201830_2/config_info.dat
