pls set batch_size in ur command

you can use `GetUpdater()->Save(bool save_aux, dmlc::Stream *fo)` in such as sgd_learner.cc and Save(bool save_aux, dmlc::Stream *fo) should be implemented first eg: (just a draft) ``` void SGDUpdater::Save(bool save_aux, dmlc::Stream *fo)...

Very nice, Look forward to the changes :)

see [dump.cc](https://github.com/CNevd/Difacto_DMLC/blob/master/src/difacto/dump.cc)

@formath @toughJack see [issues/8](https://github.com/CNevd/Difacto_DMLC/issues/8) just comment `//pair_[i].k = ReverseBytes(blk.index[i]);` will make ranges of servers imbalanced if your max key is small

@mli yes:)
