PMem Common

PMem common package includes native libraries and JNI interface for Intel Optane PMem.

Prerequisites

Below libraries need to be installed in the machine

• Memkind

• Vmemcache

memkind installation

The memkind library depends on libnuma at the runtime, so it must already exist in the worker node system. Build the latest memkind lib from source:

git clone -b v1.10.1 https://github.com/memkind/memkind
cd memkind
./autogen.sh
./configure
make
make install

vmemcache installation

To build vmemcache library from source, you can (for RPM-based linux as example):

git clone https://github.com/pmem/vmemcache
cd vmemcache
mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=/usr -DCPACK_GENERATOR=rpm
make package
sudo rpm -i libvmemcache*.rpm

Building

git clone -b <tag-version> https://github.com/oap-project/pmem-common.git
cd pmem-common
mvn clean package -Ppersistent-memory,vmemcache
