LibRDPMA, tools to analysis the performance when accessing NVM with RDMA

LibRDPMA provides a set of tools to analyze the behavior when accessing NVM (i.e., Intel Optane DC persistent memory) with RDMA. These including benchmarks for one-sided RDMA and two-sided RDMA and tools to analyze NVM behavior.

Getting Started

Building the tools of librdpma is straightforward since it will automatically install dependencies. Specifically, using the following steps:

• Clone the project with git clone https://github.com/SJTU-IPADS/librdpma.git --recursive
• Make sure cmake is installed. Then execute cmake .
• Build the project with make.

Running benchmarks

For the built binaries, ./nvm_rrtserver and ``./nvm_rrtclientare used for evaluating two-sided performance, while./nvm_serverand./nvm_clientare used for evaluating one-sided performance. We provide scripts to run experiments. For how to configure these binaries, please usebinary --help` to check.

We've also provide scripts to run experiments. For example, to run one-sided evaluations, use the following:

• cd scripts; ./bootstrap-proxy.py -f run_one.toml; Note that run_one.toml should be configured according to your hardawre setting. It is straightforward to configure it based on its content.

Other tools

We provide some tools for make system configurations or monitor NVM statistics.

• To tune DDIO setups, use cd ddio_tools; cmake; make; and then use setup_dca.

• To monitor NVM read/write amplications, use cd nvm; python analysis.py. Note that ipmctl should be installed.
