MRA++

MapReduce with Adapted Algorithms to Heterogeneous Environments, is based on MRSG Project. On September 2016 was concluded the update of MRA++ to the volatile environment, adding failure-recovery mechanisms. MRA++ now is called MapReduce with Adapted Algorithms to Volatile and Heterogeneous Environments.

To run the example, follow these steps:

1. Make sure you have installed SimGrid (3.14.159 recommended). (http://simgrid.gforge.inria.fr/)

2. Inside MRA's root and examples directories, edit the Makefiles and change the INSTALL_PATH variable to match your SimGrid installation path (e.g. /usr).

3. Compile MRA with 'make' in the command line, and then do the same for the example.

4. Execute the example (./run.sh).

Into examples folder, has platform samples. Install the python before for running, in order to create another platforms.

Syntax: platform_file.xml num_workers cores_per_node_min[:numCores_max] cpu_min[:cpu_max] latency_min[:latency_max] bw_min[:bw_max]'
