My first masterpieceMy first masterpiece

• “Analysis of numerical schemes for the integration of elastic waves” as thesis for my degree in Mathematics at the “Università La Sapienza, Rome”

• Written at ECSEC (now closed) of IBM, Rome.

• I was also dispatching mathematics students around Europe with the Erasmus programme.

My second masterpieceMy second masterpiece

• “p-adic methods for round-off errors”, the thesis of my Ph.D. in Dynamical Systems, Queen Mary, University of London.• Round-off is the error introduced by the

fact that a computer is hardware, so while doing your calculations it will store the numbers truncating them.

• p-adic numbers are numbers in base p whose distance is such that close numbers can be “far” on the real line. Ex. In 3-adic, 13 and 4 are closer than 13 and 14.

My first (really) paid jobMy first (really) paid job

• Research Assistant at the Centre of Software Reliability, City University, London• This is “the place to be” in reliability

• Try to google “Centre Software Reliability”• Try to google “Littlewood+reliability”

• My main areas of research• Assessing the reliability of open source

software• Modeling diversity as a way of increasing the

reliability of a system without increasing the reliability of its components.

EDG: the file cataloguesEDG: the file catalogues

• Part of WP2, data management• It was the time when Markus was keeping

together the testbed• And files were moved around using gdmp,

and the edg replica manager…• The file catalogue were then “Spitfire”, the

RLS, the LRC, the RMC.

• Testing Spitfire and the LRC• Writing an installer for the LRC and RMC

• for the oracle DB• For The oracle 9iAS• To upload the LRC and RMC schemas

• Part of the middleware testing team (with Mario Reale and David Collados)• Managing the CERN testing testbed, part

of a small but distributed testbed• Kickstart and quattor

• Writing and running the “rpm build validation test” suite

• Compliance check list for rpms

• Installing and updating various services times and times again (at least weekly)

• VOMS, FTS, FPS.

• Part of the CERN Regional Operations Centre (ROC) team• Dealing with GGUS tickets• Setting up a certification procedure for new

sites• Setting up the CERN ROC ticketing system (and

associated procedures)

• COD (grid operator) shifts • The reference point for GGUS and CERN

ticketing system (aka remedy), and their mis-interactions

EGEE II: user supportEGEE II: user support

• Chair of the ESC, the user support committee, now reborn as USAG

• Coordinating the GGUS work (together with Alistair)

• I was the inventor of the “shopping list”, the savannah project to prioritize and keep track of GGUS development

• You can blame me for the GGUS Escalation Reports to raise long standing tickets

• And thank me for the abolishment of escalation mails…
