Thank you for downloading the Data-Intensive Memory-Map Runtime
(DI-MMAP) and Persistent Memory Architecture Simulator (PerMA Sim) repository.
This code was developed at Lawrence Livermore National Laboratory to
provide a high-performance memory-map runtime and a simulator to test
future NVRAM storage technologies at scale.

DI-MMAP:

The DI-MMAP runtime is a high performance memory-map runtime that
offers the following features:

1) a fixed sized page buffer
2) minimal dymaic memory allocation
3) a simple FIFO buffer replacement policy (optimized for unstructured
	data access patterns)
4) preferential caching for frequently accessed pages

To use the DI-MMAP runtime a kernel module must be compiled and
inserted into the running kernel.  Currently it has been tested with
Linux RHEL6 2.6.32 kernels.  Instructions for compiling the code are
found in README_compiling.txt.

Once the DI-MMAP module is loaded, the DI-MMAP runtime can be used in
one of two ways.

1) Direct file link: A di-mmap pseudo file is created in the /dev file
   system and it is linked to a block device.

2) DI-MMAP file system: A virtual file system (di-mmap-fs) is mounted
   and it is configured to use a directory as a backing store

A paper describing DI-MMAP was published at the DISCS 2012 workshop.
