ec2_submit_workers(1)

NAME

ec2_submit_workers - submit and run work_queue_worker on the Amazon EC2 service.

SYNOPSIS

ec2_submit_workers [options] <servername> <port> <EC2-key-name> <EC2-key-file> <num-workers>

DESCRIPTION

ec2_submit_workers submits and runs work_queue_worker(1) on the Amazon EC2 service. It calls EC2-run-instances and EC2-describe-instances that are part of the EC2 API tools to create EC2 instances and run work_queue_worker on them. The number of EC2 instances created is given by the num-workers argument since each instance runs one work_queue_worker. The servername and port arguments specify the hostname and port number of the master for the work_queue_worker to connect. These two arguments become optional when the auto mode option is specified for work_queue_worker. The EC2-key-name argument specifies the name of the key to use in authenticating to the EC2 service. The EC2-key-file gives the path of the file containing the (private) key.

OPTIONS

`-a`	Enable auto mode for work_queue_worker.
`-s`	Run as a shared worker.
`-N <name>`
	Preferred project name for work_queue_worker to connect.
`-C <catalog>`
	Set catalog server for work_queue_worker to . format: HOSTNAME:PORT.
`-t <seconds>`
	Abort work_queue_worker after this amount of idle time (default=900s).
`-i <image_id>`
	EC2 OS image ID. Default = ami-fa01f193 (Ubuntu 10.04 x86_64).
`-z <instance_size>`
	EC2 instance size. Default = m1.large.
`-p <parameters>`
	EC2-run-instances parameters.
`-h`	Show help message.

EXIT STATUS

On success, returns zero. On failure, returns non-zero.

EXAMPLES

Submit 10 work_queue_worker instances to run on EC2 service using key_1 as the authentication key whose private key string is found in key_1.priv. Run work_queue_worker in auto mode with the preferred project name set to Project_A and abort timeout set to 3600 seconds:

ec2_submit_workers -a -t 3600 -N Project_A key_1 key_1.priv 10
