This post will explain the onboarding procedure from RedHen. The objective is to be able to work in the high performance computing environment provided by RedHen. In order to get access to this, several steps were required.

Main On-boarding Steps

  1. Login for case western reserve university

    First, submit information to RedHen required to create an account, and then you will receive an email from case with information about how to log in and create an email address. The email address provided should be firstname.lastname@case.edu. This can be used to log in to email at http://webmail.case.edu.

  2. Login for CWRU network

    Using links provided in the previous email, you can also set up the CWRU network login which will be a randomly assigned username in the format abc123. This username can be used to get into the vpn, and also to sign in here: login.case.edu

  3. Logging in to vpn

    To log into the VPN, cisco AnyConnect can be used. The network to log into is vpn.case.edu. Once this is entered, you will need your CWRU network login, and the password you set for it. This log in will also show a field to fill in called second password. This second password comes from Duo. Duo can be set up for Case following these instructions. The main idea is download the app Duo, and connect it with the Case account. The second password to enter will be the numerical code shown in the app.

  4. Ssh into the HPC

    In the terminal, ssh @rider.case.edu, where caseID is the abc123 CWRU login. More guidelines can be found [here](https://sites.google.com/a/case.edu/hpcc). Once in the HPC, the home directory will be /home/abc123, and the path where you will have room to store data will be /mnt/rds/redhen/gallina/home/abc123. Next, follow steps to set up ssh keys, as will be explained in an email from RedHen.

  5. Using Singularity

    In order to use Singularity, it must exist in the path. You can test Singularity by pulling from RedHen’s singularity hub, and running the container:

     singularity pull --name deepspeech-temp.img shub://RedHenLab/singularity_containers:deepspeech2

Summary

The hardest part of this process was figuring out which logins were for which, and what to put as “password 2” in logging in to the vpn. Hopefully this summary will fill in the blanks for some future students.
