RDMA ringbuffer demo

A implementation of the ringbuffer part of FaRM.

A benchmark is used to test throughput performance under different message size. The benchmark program contains a producer and a consumer.

• producer produces message in a fixed size.
• and consumer consumes it.

How to use the benchmark:

1. Modify include/demo.h:

   • producer_name and consumer_name These two value will be used to reach the other side. It can be the same if you want to run the benchmark locally.
   • device_name run command ibv_devinfo and fill it with the hca_id you want to use.

2. Run mkdir build && cd build and cmake .. and make (or make -j if you want to speed it up)

3. Copy the whole working directory to the producer side and consumer side.

4. Run ./producer and ./consumer in the corresponding server.

5. Wait for the test result. The whole process typically takes about 20~40 minutes for 100GB testing. The result will be printed to the terminal, and you can also get it from build/prod.csv in the procuder side.

There are some other adjustable configurations, see demo.h.

p.s.: Sorry for the inconvenience out of the poor organization of the project and the old-fashioned code.
