scalloc provides general-purpose memory allocation involving many threads on many cores can be done with high performance, multicore scalability, and low memory consumption. The main ideas behind the design of scalloc are: uniform treatment of small and big objects through so-called virtual spans, efficiently and effectively reclaiming free memory through fast and scalable global data structures.

scalloc - A Fast, Multicore-Scalable, Low-Fragmentation Memory Allocator

jemalloc is a general purpose malloc(3) implementation that emphasizes fragmentation avoidance and scalable concurrency support. It is intended for use as the system-provided memory allocator, as in FreeBSD's libc library, as well as for linking into C/C++ applications. jemalloc provides many introspection, memory management, and tuning features beyond the standard allocator functionality.

Apache Mnemonic is a non-volatile hybrid memory storage oriented library, it proposed a non-volatile/durable Java object model and durable computing service that bring several advantages to significantly improve the performance of massive real-time data processing/analytics. developers are able to use this library to design their cache-less and SerDe-less high performance applications.

Node Cache - A node internal (in-memory) caching module

Persistent memory (or pmem for short) is accessed like volatile memory, using processor load and store instructions, but it retains its contents across power loss like storage. This project focuses specifically on how persistent memory is exposed to server-class applications which will explicitly manage the placement of data among the three tiers (volatile memory, persistent memory, and storage).
