Induction Week Overview of Physics Computing Ian McArthur - Physics IT Manager 6th October 2014 Organisation of Physics IT support Most of IT support is centralised, i.e. shared across the whole department. Central covers general desktop support (windows, Mac OSX, Linux), email, network, databases, web etc – things that can be effectively shared across the department. There is some sub-department support which is generally for computational work, Linux based. Some sub-departments such as PP have their own Linux support staff supporting their own computing clusters and subject specific applications. Particle Physics IT strategy Desktops as general purpose devices (mainly MS windows some Linux) Access to centralised compute and data servers – clients use X-windows, SSH or RDP to connect to interactive sessions on the servers. Provides access to the widest range of applications – familiar desktop interface. Desktop systems are provided in the Oxford offices at remote sites (CERN), laptops for those travelling regularly if they have a good case (usually year 2 onwards). Provide local compute farms for final-stage analyses, rapid turn around and interactive work (known as the local cluster, or tier-3) – large runs are done on the grid. Most of LHC reconstruction and Monte Carlo should be grid based. Currently about 544 cores and 600TB in local cluster, about 1768 cores and 1300TB in local tier-2 grid resources. We make all necessary services available remotely, e.g. email (including web based), ssh to compute servers, remote file access etc. PP Training and Support • There is help for new Particle Physics students at http://www2.physics.ox.ac.uk/research/particle-physics/particle-physicscomputer-support • Local PP courses • Two double Lectures starting in Mid October. These attempt to get you using the local facilities effectively and as quickly as possible. We try to concentrate on the specifics of PP applications and the Oxford systems . 1: Overview, 2:Local Cluster, 3:Large Scale Computing 4:Python and pyROOT  2 Introduction to Programming in C/C++ in weeks 1 and 2. Please sign up with [email protected] if interested)  More advanced object-orientated programming workshops in week 9. • We will circulate information on other courses at IT services, RAL etc whenever we hear of them. • Use generic email addresses to ask for help with PP Linux systems  [email protected] (Linux) • See the Introductory Computing Manual (http://wwwpnp.physics.ox.ac.uk/~west/intro_manual/intro_manual.html) which you should work through online. • Library of computing books (Room 661) Who does what in IT ?

Always check conditions with IT support staff if you are unsure. Media Services Unit Poster printing Bulk printing Photography Meeting Room/Lecture Theatre support Videoconferencing systems (room and desktop/laptop based) Desktop and Laptop image loading Steve Lee Darren Wallace Duncan Vivian General Training and Support • Courses at the University IT services(apply early) • Use support information on the web. Please check FAQs before going to IT support staff – it’ll make you popular! • We want to improve the web pages – please tell us what you’d like to see there. (start at http://www.physics.ox.ac.uk/it) • Use generic email addresses to ask for help [email protected] (windows + general queries) [email protected] (network) • OU IT services (OUCS) offer a number of computing courses suitable for various levels. You can browse these at http://www.it.ox.ac.uk/courses/. Log-in requires your campus SSO account, (user name of the format abcd1234), which should have been provided to you by your college. None of you are signed up to any of these automatically. • For those of you that are quite new to Linux, we recommend that you sign up to one or more of their introduction to Linux courses. Accounts Physics Network account  Login to most central physics services (all operating systems) MS Windows , Apple OSX and Linux desktops VPN (remote tunnelling into our network) web pages that require authentication or for editing Connection to the department’s wireless network (physics_s) Etc etc PP Unix login  Only required to log in to older PP Linux servers and desktops in the cryo lab. Grid certificate  To allow you access to grid resources worldwide (and local) University Single Sign On (SSO)   University mail system (nexus) Various campus wide services (e.g. VPN, WebLearn, HFS backups, wireless services etc) Never share account details with anyone, including us!! Security Access to the building – first physical barrier – Obey the rules. Personal – don’t leave your valuables about – insurance never covers the cost of laptops because of excesses. Insure your own. Network – Never reveal your passwords to anyone. Client Security     Centralisation of management wherever possible Reduces manpower required Ensures minimum acceptable patch levels Un-trusted machines (e.g. self-managed laptops) are placed on a separate network and given similar access right to systems anywhere on the internet. Backups (data security)     Windows and UNIX system backed up weekday nights Data disks are often too large to be backed up. So keep your data in the right place to take advantage of this valuable service. Don’t be tempted to keep your files on local system disks or laptops. If you aren’t sure, please ask, don’t wait for a disaster. Email The Department has own Exchange system but this is running down over the next few years in favour of the campus system NEXUS. All new mailboxes after Sep 2014 (including yours !) will be on NEXUS. You will probably have been given a college email address and you will also have an @physics.ox.ac.uk address which we set to forward to the same mailbox on NEXUS. Nonetheless, please be careful to make sure you’re reading all your mailboxes, or forwarding all to one place. Please assume that your physics.ox.ac.uk will always be forwarded to NEXUS. If you want to forward onto some external provider such as gmail, hotmail etc, then this can be done on NEXUS. Do’s and Don’ts • Get to know the IT support staff. They are here to help you to do your work more effectively. Help the IT support staff to help you. Feedback is very important ! • Always contact IT support staff if you need • • • • • More network connections A system moved A system fixed or upgraded New software installed Make IT related purchases (software or hardware) • Never attempt to connect any system to the wired network without permission of IT support staff who will provide the necessary configuration details. • Use the web pages (FAQs) to try to solve problems. Try http:///www.physics.ox.ac.uk/it OR http://www2.physics.ox.ac.uk/research/particle-physics/particle-physics-computer-support • Check licensing terms and conditions before running any software on your privately owned systems • Be aware of all the rules and policies in place…….
