Quick start guide

If you want to just dive in, just press the "Windows" (or super) key the Ubuntu "dash" will open up. From there you can access all programs by typing in either the name of the program or function. For example, if you want to open a spreadsheet, just tpye "spreadsheet" and libre office will be shown as an application to use. Click the application to open it.

The only methods to connect to the interactive servers are via either SSH or Remote Desktop Protocol. For security reasons, users cannot connect directly to these services, but must connect via a bastion or proxy service.

Connecting to the Interactive Servers via SSH

From Windows 10 OS

PuTTY is the preferred option – available from “Physics Self Service” on department-managed systems.​

Introduction/Scope

This page documents how to tidy up files and directories in data areas. The documentation contains specifics for LHCb and ATLAS data areas, but some of the info is useful for other data areas and home directories.

NOTE: Data areas are not backed up!!

multirun is a fairly simple program written in C (ask me for the source if you want) for running lists of commands/programs in parallel (at the same time) on multiple compute nodes. It can be useful if you have lots of "normal" - serial - programs that you want to run at the same time, with different parameters. It uses a file called "params.txt" to tell it what it should run.
For example, if you fill the file "params.txt" with:
/users/me/myProgram 311232 1231231
/users/me/myProgram 232377 8127387
etc...

Linux Desktops

Theoretical Physics provides a unified, multi-user desktop system for its members to perform day-to-day computing tasks and smaller numerical tasks. The system is based around Dell Optiplex 9020s with 8GB or 24GB of RAM, and Lenovo M9xx desktop clients with 16GB or 24GB of RAM.

Scientific data analysis and visualisation.

We never enabled the network software on laptops by default. There are a number of reasons for this:
