Here hosts resources for benchmarking newly proposed persistent memory range indexes on Pibench, including benchmark, wrapper generation and results parse scripts (generate_wrappers.sh, benchmark.py, parse.py). Also contains source code of five PM indexes + two DRAM index (see below).

See detailed analysis in our VLDB 2022 paper:

git clone https://github.com/sfu-dis/pibench-ep2.git
cd pibench-ep2
git submodule update --init --recursive

• CMake with VERSION >= 3.14 (pip install cmake --upgrade)
• glibc with VERSION >= 2.34
• PiBench: for running all benchmarks. Will be automatically cloned and built if run benchmark.py
• PMDK: required by most indexes for persistent memory management.
• HTM(TSX support) needs to be turned on for FPTree and LB+-Tree. See FPTree README for details.

To generate pibench wrappers for selected indexes:

sudo ./generate_wrappers.sh 

or

The README in each index directory contains instructions for building each individual PiBench wrapper:

The benchmark script will clone and built pibench for you if it is not found in current folder.

Run it under default settings (Warning! This could take hours to finish!):

sudo ./benchmark.py

or if wish to run selected experiments for selected indexes with customized parameters:

Tune variables in the script:

repeat - # runs for each data point (default 1)

base_size - size of base index before benchmark (default 100M)

seconds - # seconds of operation after load phase (default 10) 

pibench_path - path to PiBench executable (default pibench/build/src/PiBench)

lib_dir - path to PiBench wrappers (default wrappers/)

result_dir - path to folder that stores benchmark results (default ./results)

pool_path - location to place PMem pool (default "" means PMem pool will be created in current dir)

There are 6 types of supported experiments, Choose type of experiment and configuations by modifying variables between line 57 ~ 86:

Uniform/Skewed/Mixed/Latency/NUMA/VarKey - Specify selected experiments for selected indexes (by default all experiments are selected with all supported indexes)

*_threads - Specify threads for each experiment (default [40,30...1])

*_ops - operation types (default all supported types are included)

self_similar - skew factor for Skewed experiment (default 0.2)

sampling - percentage of samples collected for Latency experiment (default 0.1)

By default the experiment results should be saved in ./results folder.

To generate .csv files for all experiments:

./parse.py

or

modify script to generate .csv for specific experiment (see line 294 and beyond)
