    |---- YCSB_memcached (Yahoo! Cloud Serving Benchmark: Memcached) 
    |---- YCSB_rocksdb   (Yahoo! Cloud Serving Benchmark: RocksDB)

Environment:

Our artifact should run on any Linux distribution. The current scripts are developed for Ubuntu 20.04.3 LTS.

Setup

Note: For the below steps, our scripts will complain if it fails to compile or install the target. Check the end part of the scripts' output to ensure that the install is successful. Also, some scripts would prompt to ask the sudo permission at the beginning.

1. Install the dependencies:

$ ./dep.sh

1. Install the 5.4.147-ScaleCache Linux kernel (50GB space and 20 minutes)

$ cd kernel
$ cp config-scalecache .config
$ make oldconfig             (update the config with the provided .config file)

Next, please use your favorite way to compile and install the kernel. The below step is just for reference. The installation requires 50GB space and takes around 20 minutes on our machines.

The classical ways will work as well:

$ make -j64              
$ make -j64 modules 
$ sudo make -j64 modules_install
$ sudo make -j64 install

Reboot the machine to the installed 5.4.147-ScaleCache kernel.

3. Install and insmod file systems

$ cd scext4
$ make -j64
$ make install
$ sudo modprobe jbd3
$ sudo modprobe scext4
$ sudo mount -t scext4 DEVICE MOUNTPOINT

The script will compile, install, and insert the following kernel modules:

  • jbd3
  • scext4

4. Compile and install benchmarks

4.1 FFSB

$ cd workloads/ffsb
$ ./compile.sh

4.2 Filebench

$ cd workloads/filebench
$ ./compile.sh

4.3 sysbench

$ cd workloads/sysbench
$ ./compile.sh

4.4 YCSB

$ cd workloads/YCSB_memcached
$ ./compile.sh
