HPMMAP: High Performance Memory Mapping and Allocation Platform

About

HPMMAP is a lightweight memory manager for commodity operating systems. It provides a memory management stack that can support unmodified high performance computing (HPC) applications running on Linux. HPMMAP has the following characteristics:

• Lightweight memory management
• Fully automatic large page (2MB/1GB) support
• "On-request" mapping: no page faults
• Linux kernel module implementation
• No kernel modification required
• Invoked via system call inter-positioning
• No application modification required

Architecture

HPMMAP is designed to co-exist with an unmodified Linux memory subsystem. The resulting architecture allows both HPC and commodity-class applications to co-exist on the same machine without sharing a memory management stack that is necessarily better at supporting one than the other.
