FpgaNIC is an FPGA-based Versatile 100Gb SmartNIC for GPUs

FpgaNIC

FpgaNIC is an FPGA-based, GPU-centric, versatile SmartNIC

1, that enables direct PCIe P2P communication with local GPUs using GPU virtual address,

2, that allows GPUs to directly manipulate FpganIC without CPU intervention,

3, that provides reliable 100Gb network access to remote GPUs, and

4, that allows to offload various complex compute tasks to a customized data-path accelerator for line-rate in-network computing on the FPGA, thereby complementing the processing at the GPU.

Besides, FpgaNIC enables efficient efficient FPGA-GPU co-processing.

Check-list

1. At least two nodes, each has a GPU that supports NVIDIA GPUDirect and a Xilinx U280 or U50 card.

2. Each FPGA card is connected to a 100Gbps Ethernet switch.

3. FPGA card and GPU are connected to the same PCIe switch.

4. Host OS: Linux 4.15.0-20-generic

5. Nvidia Driver Version: 450.51.05

6. CUDA Version: 11.0

7, Make sure that each server has enabled Hugepages.

How to run Experiment: Three steps.

There are three steps to run each experiment. Before running FpgaNIC, please clone the source code:

$ git clone https://github.com/RC4ML/FpgaNIC

Hardware: FPGA Bitstream

1. $ cd bitstream

2. Using vivado and flush the bitstream to every FPGA card.

3. Every time you download the bitstream to the FPGA, you have to reboot the machine, do not forget to reinstall xdma driver and GDR driver.

Software: Driver Installation

1. $ cd FpgaNIC/driver

2. $ make && sudo insmod xdma_driver.ko

3. $ cd FpgaNIC/gdrcopy

4. $ sudo ./insmod.sh

5. Note that you need to reinstall xdma driver and gdr driver every time you reboot your machine.

Software: Running Application Code

1. $ cd FpgaNIC/sw && mkdir build && cd build

2. $ cmake ../src

3. $ make

4. $ sudo ./dma-example -b 0

5. $ Above command would report GPU read CPU memory latency, for more details, please refer to sw/README.md

fpganic's Issues

I didn't find the definitions of these two functions in the project

The functions socket_send_test() and socket_send_test_offload_control() are used in lines 190 and 197 in sw/src/main.cpp, but I didn't find the definitions of these two functions in the project.

Are these system functions or something else?
