computing\nlibrary where devices can enter or leave at any time, does not require any extra configuration on\nmachines and supports remote class and native library loading\n\n## Features\n\n- Distributed and parallel master worker computing\n- Supports remote class loading\n- Supports remote native library loading (.so, .dll)\n- Devices can enter or leave computation at any time\n- Fault tolerance mechanism via exceptions and timeouts\n- ~~Provides runtime conversion of java class file to Android dex format~~\n- Modular architecture\n- No configuration required\n\n##
