Overview

This module lets one create one or more redundancy descriptors, which then may be applied to a set of files distributed across a group of processes.

Usage is documented in src/redset.h, doc/rst/redset.rst, and the User API docs. Also see the example program in the test directory.

Implementation details can be found in doc/rst/implementation.rst and doc/rst/schemes.rst.

Building

To build dependencies:

git clone git@github.com:ECP-VeloC/KVTree.git  KVTree.git
git clone git@github.com:ECP-VeloC/rankstr.git rankstr.git

mkdir install

mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=../install -DMPI=ON ../KVTree.git
make clean
make
make install
make test
cd ..

rm -rf build
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=../install -DMPI=ON ../rankstr.git
make clean
make
make install
cd ..

To build redset:

cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=./install -DWITH_KVTREE_PREFIX=`pwd`/install -DWITH_RANKSTR_PREFIX=`pwd`/install .
make
make install

Testing

Some simple test programs exist in the test directory.

To build a test for the redset API:

mpicc -g -O0 -o test_redset test_redset.c -I../install/include -L../install/lib64 -lkvtree -lrankstr -I../src -L../src -lredset
