parsl.providers.AWSProvider

class parsl.providers.AWSProvider(image_id, key_name, init_blocks=1, min_blocks=0, max_blocks=10, nodes_per_block=1, parallelism=1, worker_init='', instance_type='t2.small', region='us-east-2', spot_max_bid=0, key_file=None, profile=None, iam_instance_profile_arn='', state_file=None, walltime='01:00:00', linger=False, launcher=SingleNodeLauncher())[source]

A provider for using Amazon Elastic Compute Cloud (EC2) resources.

One of 3 methods are required to authenticate: keyfile, profile or environment variables. If neither keyfile or profile are set, the following environment variables must be set: AWS_ACCESS_KEY_ID (the access key for your AWS account), AWS_SECRET_ACCESS_KEY (the secret key for your AWS account), and (optionaly) the AWS_SESSION_TOKEN (the session key for your AWS account).

Parameters:
  • image_id (str) – Identification of the Amazon Machine Image (AMI).
  • worker_init (str) – String to append to the Userdata script executed in the cloudinit phase of instance initialization.
  • walltime (str) – Walltime requested per block in HH:MM:SS.
  • key_file (str) – Path to json file that contains ‘AWSAccessKeyId’ and ‘AWSSecretKey’.
  • nodes_per_block (int) – This is always 1 for ec2. Nodes to provision per block.
  • profile (str) – Profile to be used from the standard aws config file ~/.aws/config.
  • nodes_per_block – Nodes to provision per block. Default is 1.
  • init_blocks (int) – Number of blocks to provision at the start of the run. Default is 1.
  • min_blocks (int) – Minimum number of blocks to maintain. Default is 0.
  • max_blocks (int) – Maximum number of blocks to maintain. Default is 10.
  • instance_type (str) – EC2 instance type. Instance types comprise varying combinations of CPU, memory, . storage, and networking capacity For more information on possible instance types,. see here Default is ‘t2.small’.
  • region (str) – Amazon Web Service (AWS) region to launch machines. Default is ‘us-east-2’.
  • key_name (str) – Name of the AWS private key (.pem file) that is usually generated on the console to allow SSH access to the EC2 instances. This is mostly used for debugging.
  • spot_max_bid (float) – Maximum bid price (if requesting spot market machines).
  • iam_instance_profile_arn (str) – Launch instance with a specific role.
  • state_file (str) – Path to the state file from a previous run to re-use.
  • walltime – Walltime requested per block in HH:MM:SS. This option is not currently honored by this provider.
  • launcher (Launcher) – Launcher for this provider. Possible launchers include SingleNodeLauncher (the default), SrunLauncher, or AprunLauncher
  • linger (Bool) – When set to True, the workers will not halt. The user is responsible for shutting down the node.
