Supported platforms

idmtools currently supports running on the following platforms:

COMPS: COmputational Modeling Platform Service (COMPS) is a high performance computing cluster used by employees and collaborators at IDM. To support running simulations and analysis on COMPS, idmtools includes the following modules: idmtools_platform_comps.


COMPS access is restricted to IDM employees. See additional documentation for using idmtools with other high-performance computing clusters.

SLURM: You can also run simulations on the open-source SLURM platform for large and small Linux clusters.”. For more information, see SLURM.

Local: You can also run simulations and analysis locally on your computer, rather than on a remote high-performance computer (HPC). For more information about these modules, see idmtools_platform_local.

If you need to use a different platform, you can also add a new platform to idmtools by creating a new platform plugin, as described in Create platform plugin.

You can use the idmtools.ini file to configure platform specific settings, as the following examples shows for COMPS:

type = COMPS
endpoint =
environment = Belegost
priority = Lowest
simulation_root = $COMPS_PATH(USER)\output
node_group = emod_abcd
num_retires = 0
num_cores = 1
max_workers = 16
batch_size = 10
exclusive = False

As an alternative to the INI based configurations, some platforms such as COMPS provide predefined configurations aliases. With those aliases, you can use an alias for a known environment without a config. To see a list of aliases, use the cli command idmtools info plugins platform-aliases.

Within your code you use the Platform class to specify which platform idmtools will use. For example, the following excerpt sets platform to use COMPS and overrides priority and node_group settings.:

platform = Platform('COMPS',priority='AboveNormal',node_group='emod_a')

You use the Platform class whether you’re building or running an experiment, or running analysis on output from simulations.
