Running Simulations in the Cloud (AWS) ====================================== To accelerate simulations, the model can be executed on cloud virtual machines. For example, as of this writing, a 96 Core machine (``c5.24xlarge``) can be rented from Amazon Web Services for ~$1.5/hr (spot price). The basic usage cycle involves the following steps: - Request a 'spot' instance from AWS (spot instances are ~70% less expensive) - SSH into the instance, download the model docker image, run the simulation - Upload simulation results for later analysis - Shut down instance (per-second billing) A similar process can be followed with other cloud providers (GCP, Azure, etc...). ========================== Private Cloud MPI Clusters ========================== Similarly, multiple instances could be started to form a private MPI cluster, and the simulation could be distributed across multiple instances. See `AWS ParallelCluster `_.
