To activate\nthis mode, simply do *not* specify any hosts ('-N' argument). For instance,\n\n```\n./sim.py -c 2 -n 4 workflows/montage_60.xml\n```\n\nsimulates a single host with 2 cores and 4 AFEs.\n\nThis simulation mode relies on the scheduler from the [libanalyzethis](https://github.com/sandrain/libanalyzethis)\nlibrary. To enable it,\nyou must specify where the library is installed using the `PYTHONPATH` environment variable.\n\n```\nexport PYTHONPATH=/where/libanalyzethis/is/src:$PYTHONPATH\n```\n\n### Multi-host Simulation\n\nThe simulator can be used to simulate a distributed platform. In this context, the simulated\ndistributed platform can include several servers (nodes hosting the AFEs) and several\nclients. This mode requires the [libanalyzethis](https://github.com/sandrain/libanalyzethis)\nlibrary and it is required to specify where\nthe library is installed using the `PYTHONPATH` environment variable.\n\n```\nexport PYTHONPATH=/where/libanalyzethis/is/src:$PYTHONPATH\n```\n\nTo activate the multi-host mode, simply specify the number of nodes on the command line:\n\n```\n./sim.py -N 2 -c 2 -n 2 workflows/montage_60.xml\n```\n\nThis will simulates 2 server nodes, each node having 2 cores and 2 AFEs.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsandrain%2Fanalyzethis-schedsim","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsandrain%2Fanalyzethis-schedsim","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsandrain%2Fanalyzethis-schedsim/lists"}
