Board used: Alveo U55C High Performance Compute Card

Software Version: 2022.2

This project presents QuErK, a framework to accelerate Quantum Error Correction on FPGAs, achieving a top speedup of 49x with respect to software. We consider the Sparse Blossom Algorithm, that is devoted to find the best correction to apply to qubits, and implement a dataflow architecture with pipelining to accelerate the most compute-intensive component of such an algorithm.

src folder: contains the source files for kernel and host

• kernel_dataflow.h : header file for the kernel
• kernel_dataflow.cpp : source file for the kernel
• host.cpp : source file for the host
• host_arguments.hpp : utility source file for the host, for n = 22000 neighbors
• software.py : source file for the software version of the accelerated component
• software_arguments.py : utility source file for pure software, for n = 22000 neighbors

Makefile: makefile to automate design generation, build the host application and run software emulation, hardware emulation and hardware.

• makefile_us_alveo.mk : utility file for Makefile
• utils.mk : utility file for Makefile
• querk.cfg : cfg file used by Makefile
• setup.sh : script file to get most common commands.

bin folder: contains the binary of the host and the bitstream of the hardware for Alveo U55C

• querk : binary of the host
• querk.xclbin : bitstream of the hardware for Alveo U55C

1. source the required sh files for Vitis and XRT:

   • source path/to/settings64.sh
   • source path/to/xrt/setup.sh
   • export PLATFORM_PATH=path/to/xilinx/platforms/

2. to build and run software emulation (for u55c):

   • make all TARGET=sw_emu
   • make run TARGET=sw_emu

3. to build and run hardware emulation (for u55c):

   • make all TARGET=hw_emu
   • make run TARGET=hw_emu

4. to build and run hardware (for u55c):

   • make all TARGET=hw
   • make run TARGET=hw

5. to only compile the host (called ./querk) and run separately:

   • make host
   • ./querk path/to/querk.xclbin

6. to run the software version of the accelerated component:

   • python3 src/software.py
