Covalent SSH Plugin
Covalent is a Pythonic workflow tool used to execute tasks on advanced computing hardware. This executor plugin interfaces Covalent with other machines accessible to the user over SSH. It is appropriate to use this plugin to distribute tasks to one or more compute backends which are not controlled by a cluster management system, such as computers on a LAN, or even a collection of small-form-factor Linux-based devices such as Raspberry Pis, NVIDIA Jetsons, or Xeon Phi co-processors.
To use this plugin with Covalent, simply install it using pip:
pip install covalent-ssh-plugin
The following shows an example of how a user might modify their Covalent configuration to support this plugin:
[executors.ssh]
username = "user"
hostname = "host.hostname.org"
remote_dir = "/home/user/.cache/covalent"
ssh_key_file = "/home/user/.ssh/id_rsa"
This setup assumes the user has the ability to connect to the remote machine using ssh -i /home/user/.ssh/id_rsa user@host.hostname.org and has write-permissions on the remote directory /home/user/.cache/covalent (if it exists) or the closest parent directory (if it does not).
Within a workflow, users can decorate electrons using the default settings:
import covalent as ct
@ct.electron(executor="ssh")
def my_task():
import socket
return socket.gethostname()
or use a class object to customize behavior within particular tasks:
executor = ct.executor.SSHExecutor(
username="user",
hostname="host2.hostname.org",
remote_dir="/tmp/covalent",
ssh_key_file="/home/user/.ssh/host2/id_rsa",
)
@ct.electron(executor=executor)
def my_custom_task(x, y):
return x + y
