A Design Space Exploration and Evaluation for Main-Memory Hash Joins in Storage Class Memory.

Code repository for our VLDB'23 paper.

Prerequisites

1. A two-socket machine with 2nd 2nd Gen Intel® Xeon® Scalable Processors.  
2. 1.5TB Intel Optane DIMMs.  

Note: If you do not meet the above requirements, you may not be able to reproduce all the experimental results.  

Dependencies

Install PMDK:

$ aptitude search pmem
$ apt-cache search pmem
$ apt search pmem

$ apt-get install <library>

All Runtime: 
$ sudo apt-get install libpmem1 librpmem1 libpmemblk1 libpmemlog1 libpmemobj1 libpmempool1
All Development: 
$ sudo apt-get install libpmem-dev librpmem-dev libpmemblk-dev libpmemlog-dev libpmemobj-dev libpmempool-dev libpmempool-dev
All Debug:
$ sudo apt-get install libpmem1-debug librpmem1-debug libpmemblk1-debug libpmemlog1-debug libpmemobj1-debug libpmempool1-debug

Install daxctl

sudo apt install daxctl

Install ndctl

sudo apt install ndctl daxctl

Install ipmctl

$ sudo apt update
$ sudo apt search ipmctl
$ sudo apt info ipmctl

Install ipmctl

Install PAPI

Install PAPI

Install Intel-PMWatch

$ sudo apt update -y
$ sudo apt install -y autoconf automake libtool libconfig-dev libkmod-dev libudev-dev uuid-dev libipmctl-dev libnuma-dev

Install Intel-PMWatch

Install Other Packages

$ sudo apt install -y numactl
$ pip install -r requirements.txt

Grant Permissions (for PAPI):

sudo sh -c "echo -1 >/proc/sys/kernel/perf_event_paranoid"
sudo sh -c "echo 0 > /proc/sys/kernel/kptr_restrict"

Quick Start

Compile & Build

$ ./revitalize.sh

Data Generation

$ ./bin/gen

Running Joins

To run NPHJ-SC: 
$ ./bin/main --workload=uniform --subtype=A --param=pkfk --algo=nphj_sc

To run RDX-BC with the bandwidth regulation mechanism:
$ ./bin/main --workload=uniform --subtype=A --param=pkfk --algo=phj_radix_bw_reg_bc

Note: You can also run all joins in DRAM by simply disabling the USE_NVM variable in CMakeLists.txt.

Reproducing Experiments

See scripts/.
Note: You may want to amend the paths of SCM mounting points, PMWatch, and PAPI in src/ before running the experimental scripts.

Hardware Configuration

Since the experiments depend on special hardwares, the hardware configuration practices are available under request.
