UMAP v0.0.3 (alpha)

Documentation Status

Umap is a library that provides an mmap()-like interface to a simple, user- space page fault handler based on the userfaultfd Linux feature (starting with 4.3 linux kernel). The use case is to have an application specific buffer of pages cached from a large file, i.e. out-of-core execution using memory map.

The src directory in the top level contains the source code for the library.

The tests directory contains various tests written to test the library including a hello world program for userfaultfd based upon code from the userfaultfd-hello-world project.

Quick Start

Building umap is trivial. In the root directory of the repo

mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX = <where you want the sofware> ..
make install

The default for cmake is to build a Debug version of the software. If you would like to build an optimized (-O3) version, simply run

cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX = <where you want the sofware> ..

Documentation

Both user and code documentation is available here.

If you have build problems, we have comprehensive build sytem documentation too!
