Induction Week Overview of Physics Computing Ian McArthur - Physics IT Manager 7th October 2013 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. Some sub-department support which is generally for computational work, Linux/UNIX based. Some sub-departments have their own UNIX support staff supporting their own computing clusters and subject specific applications. Particle Physics IT strategy Desktops as general purpose devices (mainly MS windows) Access to centralised compute and data servers – clients use x-windows, ssh etc 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 testing and interactive work – large runs are done on the grid (known as the local cluster, or tier-3). Most of LHC reconstruction and Monte Carlo should be grid based. Currently about 380 cores and 470TB in local cluster, about 1340 cores and 720TB 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 • 4 Lectures starting Thursday 17th Oct at 11.00. 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:Grid Overview 4:Pyphon and pyROOT. 2-day Object Orientated Programming workshop in week 9 • We will circulate information on other courses at IT services, RAL etc whenever we here 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.

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) Mail system web pages that require authentication or for editing Connection to the department’s wireless network (physics_s) Etc etc PP Unix login Login to PP Linux servers (mainly for computation) 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 !! 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 Exchange email server backed up several times per day. 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. Email Department has own Exchange system including calendar’s, tasks, contacts etc. Accessible with any IMAP client, Outlook, Web, OSX mail, phones (activesync) etc Please be careful to make sure you’re reading all your mailboxes, or forwarding all to one place. We can forward physics emails on for you but please be aware that you’ll need to use your internal account to access some email lists because they are closed. 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 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……. Misuse Unacceptable behaviour includes but isn’t limited to attempting to gain unauthorised access to a facility; making offensive material available over the Web; generating, sending or receiving pornographic material; using someone else's username and/or password; disregarding the privacy of other people's files; giving your username or password to someone else, or being otherwise careless with them; generating messages which appear to originate with someone else, or otherwise attempting to impersonate someone else; sending messages which are abusive or a nuisance or otherwise distressing; displaying offensive material in a public place; introducing programs with malicious intent; trying to interfere with someone else's use of the facilities; disregard for "computer etiquette"; sending chain email; being wasteful of resources; software piracy (including infringement of software licences or copyright provisions) never download copyrighted material, it could end up with you being sent down!) using the facilities for commercial gain without explicit authorisation; physically damaging or otherwise interfering with facilities. IT Policies All University policies are on the web at http://www.admin.ox.ac.uk/lso/statutes/ See • • • • • Computer Usage Rules and Etiquette Data Protection: University Policy Freedom of Information Policy Information Security Policy (more info will be circulated shortly) Information Technology: Regulations Relating to the Use of Information Technology Facilities These refer to legal requirements and other external policies such as use of the academic network (JANET) and software licensing agreements. Physics Department policy adopts the above and adds a few internal policies. Please see http://www.physics.ox.ac.uk/IT/general/policies/ Information Security Policy Department must 1. Put policy and structure in place deal with reviews and issues (a small group has been formed) 2. Identify all sensitive information and perform risk assessments. 3.
