Implementation of NCCloud in C++ updated: August 2013)

We implement NCCloud in C++ to improve its performance:

Supported coding schemes: FMSR codes libfmsr), Reed-Solomon codes Jerasure) and replication
Supported storage back-ends: Local storage, OpenStack Swift
Source bundled with libfmsr and Jerasure): nccloud-c++-1.0.tar.gz August 2013) md5: d004b46ea269a1aab0fde575f7ef36bc)
Example usage in bash):

$ tar xf nccloud-c++-1.0.tar.gz && cd nccloud-c++-1.0/nccloud
$ make
$ export LD_LIBRARY_PATH="../libfmsr/lib:../Jerasure/lib:$LD_LIBRARY_PATH"  # or install the libraries any way you want
$ cp template/config_local config
$ mkdir -p store/{tmp,node{0..4}}
$ bin/nccloud config encode README template/config_local
$ bin/nccloud config repair 0 README config_local
$ bin/nccloud config decode README config_local
$ diff {,store/tmp/}README
$ diff {template,store/tmp}/config_local
$ bin/list_repo config
$ bin/nccloud config delete README config_local
$ bin/list_repo config
