Summary
This chapter showed how persistent memory’s large capacity can be used to hold volatile
application data. Applications can choose to allocate and access data from DRAM or
persistent memory or both.
memkind is a very flexible and easy-to-use library with semantics that are similar to
the libc malloc/free APIs that developers frequently use.
libvmemcache is an embeddable and lightweight in-memory caching solution that
allows applications to efficiently use persistent memory’s large capacity in a scalable
way. libvmemcache is an open source project available on GitHub at https://github.
com/pmem/vmemcache.
