picsh

Parallel Interactive Cluster Shell, for rapid ad-hoc cluster ops.

Requirements

• Tested on Linux only (Fedora 35, Amazon Linux 2, Ubuntu 18)
• Tested with Python 3.6 and up

Features

• Fast interactive shells (re-uses the ssh session)
• Stateful ($cd /var/log followed by $pwd gives you /var/log)
• Ssh to a single node to run full screen curses apps like top
• Browse receive buffers per node
• Keyboard and mouse driven
• Works over ssh so you can put this on a jump host

Demo

Setup

• Create a cluster yaml and put it in ~.picsh/cluster_name.yaml.

Example:

$ cat .picsh/slurm-dev.yaml

cluster_name: slurm-dev
login_user: ec2-user
ssh_key_path: /home/ec2-user/.keys/pcluster.pem

  - ip: "10.0.27.155"
  - ip: "10.0.25.13"
  - ip: "10.0.23.208"
  - ip: "10.0.31.113"
