This is part I of the workshop designed to prepare a biologist to work in an interactive Linux environment of our BioHPC Lab workstations. We will first explain how the BioHPC Lab fits in the broader context of computational facilities offered by CBSU and how the lab machines can be accessed remotely. We will then cover very basics of Linux operating system, needed to operate the workstations. In particular the topics will include:
-
Overview of computational infrastructure at CBSU
-
How to reserve time on BioHPC Lab workstations
-
Remote access to the workstations: ssh with text and X-Windows
-
Navigating a Linux workstation: directory structure, basic Linux commands for dealing with files and directories
-
Dealing with text files: text editors
The presented material will be illustrated by hands-on exercises hosted on dedicated workstations of the CBSU BioHPC Lab. The workstations will be accessed using the Secure SHell (ssh) protocol. To participate in the exercises, please bring your own laptop with an ssh client installed. MACs and Linux laptops come with native ssh clients and no extra installtion is needed. For windows, the recommended ssh client is PuTTy - please install it prior to the workshop. To be able to run Linux programs with graphical inerface displaying on your Windows laptop, you should also install Xming (this is not essential for the workshop). To transfer files between your laptop and a Linux machine, you will need an sftp clinet, such as FileZilla on Windows (MAC and Linux laptops come with native sfpt clients and no extra installation is needed). For links to client software mentioned above, instructions, and more information on access to BioHPC machines, please refer to the following document: http://cbsu.tc.cornell.edu/lab/doc/Remote_access.pdf, especially points 1 and 2.2-2.4.
Access to BioHPC Lab workstations requires a Lab account. If you do not yet have an account on BioHPC Lab system, we will create one for you. Also, we will assign a machine for you to work on during and after the workshop. The machine allocations will be posted on this page. Machine reservations will be active from March 4th 3:00PM until end of the day Wed March 6th..
