pmempool - Persistent Memory Pool Management Tool


pmempool [--help] [--version] <command> [<args>]


The pmempool is a management tool for Persistent Memory pool files created by NVML libraries.

The main purpose of pmempool is to provide a user with a set of utilities for off-line analysis and manipulation of pools created by pmem libraries. The pmempool is a generic command which consists of subcommands for specific purposes. Some of subcommands are required to work without any impact on processed pool, but some of them may create a new or modify an existing one.
