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

   

libfmsr: a C library for FMSR codes (updated: August 2013)

• Source: libfmsr-1.0.tar.gz (August 2013) (md5: ccfa0aa05f864ed5e11f011cb71d8a08)
• Example usage (in bash):

  $ tar xf libfmsr-0.1.tar.gz && cd libfmsr-0.1
  $ make && make test
