This directory contains code for the following paper:
Gang Liu, Leying Chen, Shimin Chen. Zen: a High-Throughput Log-Free OLTP Engine for Non-Volatile Main Memory. PVLDB 14(5): 835-848.
We implement two prototypes of Zen based on Cicada and DBx1000, respectively.
The machines should be equipped with Intel Optane DC Persistent Memory. The Intel Optane DC Persistent Memory should be configured as App-Direct mode. It uses PMDK to map NVM into the virtual address space of the process.
Suppose the NVDIMM device is /dev/pmem0, a file system is created on the device, and it is mounted to /mnt/mypmem0. Make sure we have permissions to create and read files in /mnt/mypmem0. For example, we can create a subdirectory for each user that wants to work on NVM, then use chown to change the owner of the subdirectory to the user.
The directory is organized as follows:
| Name | Explanation |
|---|---|
| README.md | this file |
| zen-cicada | zen prototype based on cicada engine |
| zen-dbx1000 | zen prototype based on dbx1000 |
| LICENSE | license for zen and its based codebase |
Please read zen-cicada/README.md and zen-dbx1000/README.md for detail usage.
