- Rabit is a library instead of framework, program only need to link the library to run, without restricting to a single framework.
* Flexibility in programming
- Many frameworks only allow user to define limited functions(map,reduce), and the framework call these operation
- Programs call rabit functions, Allreduce, CheckPoint in any sequence
- Program persist over all the iterations, unless it fails and recover.
- When program with rabit, programs call rabit functions, Allreduce, CheckPoint in any sequence
- Program persist over all the iterations, unless it fails and recover
* Fault tolerance
- Rabit program can recover model and results of functions calls
- Rabit program can recover model and results of syncrhonization functions calls(Allreduce and Broadcast)
* MPI compatible
- Codes using rabit interface naturally compiles with existing MPI compiler
- User can fall back to use MPI Allreduce if they like with no code modification
