- Work Directory (Step 1)
The steps for library download and environment setup can be found in l2_vitis_database. For getting the design:
cd L1/benchmarks/hash_multi_join
- Build Kernel (Step 2)
Run the following make command to build your XCLBIN and host binary targeting a specific device. This process will take a long time, maybe couple of hours.
make run TARGET=hw PLATFORM=xilinx_u280_xdma_201920_3
- Run Kernel (Step 3)
To get the benchmark results, run the following command:
./build_dir.hw.xilinx_u280_xdma_201920_3/test_join.exe -xclbin build_dir.hw.xilinx_u280_xdma_201920_3/hash_multi_join.xclbin
Hash Multi-Join Input Arguments:
Usage: test_join.exe -xclbin
-xclbin: the kernel name
Note
The default arguments are set in the Makefile; you can use other platforms to build and run.
- Example Output (Step 4)
