A high performance concurrent hash table for pesistent memory.

CCEH-PMDK: source code of the implementation of CCEH.

Clevel-Hashing: source code of clevel hashing, level hashing, p-clht and cceh version2.

Dash: source of dash: scalable hashing on persistent memory

data: all the orginal data, and scripts to plot the figures in the papar. Run analysis_plot.sh to re-produce the figures.

lib: external utils

src/turbo/turbo_hash_pmem_pmdk.h:: source code of TurboHash persistent verison.

src/turbo/turbo_hash.h:: source code of TurboHash dram verison.

testbench: all the benchmark scripts used in the papar.

mount your Pmem device to /mnt/pmem directory with DAX mode. For example, sudo mount -o dax /dev/pmem0 /mnt/pmem

install gflags to run test benchmark

# packages
sudo apt install libgflags-dev g++-10 gcc-10
sudo apt reinstall g++

# compile the all the code (TurboHash, CCEH, Clevel, CLHT, Dash)
bash buildall.sh

# configure performance mode
sudo bash config_cpu_performance_mode.sh

Go to folder testbench, and run the script start with testbench_*.sh

For example:

cd testbench

sudo bash testbench_scalability.sh

You may modify the number of threads in the scripts to match the CPU cores in your server.
