Curriculum Vitae of Peter Chubb

Dr Chubb is a researcher/project manager/software engineer with more than thirty-five years experience in UNIX and UNIX-related software, including over twenty-five years experience in kernel software development in a wide variety of different commercial and open-source flavours of UNIX, including Linux.



Also the WorkCover approved OH&S Consultation course, and a NSW-Fire Brigade approved Chief Warden course.

Key Experience

I have worked on a large number of different flavours of UNIX, as user, programmer, administrator and kernel programmer. These include editions 6 and 7, System V, SVr4,, UXP/M, UXP/DS, Sequent's `Balance', Pyramid's dual universe system, BSD4.2, Linux from version 0.95 on, SCO UNIX, UnixWare, XENIX, minix, Irix versions 5 through 6.5.2, Tru64, Solaris, and Reliant. In general, the software I've designed has had to be portable between different flavours of UNIX, so has had to be independent of byte ordering or word length.

I have worked on machine-dependent code for a wide variety of computer architectures, including Motorola 6800, 6809 and 68000 series microprocessors, PDP11, mips, IBM 370, Sparc, Pentium and Itanium, ARM and Alpha. Of these I would consider myself proficient only on the Motorola and Itanium chips, and maybe the ARM.

Operating Systems worked on at kernel level include:

Working toward Ph.D. in Computer Science at UNSW.
Graduated; started as Software Engineer at Softway Pty Ltd.
Senior Software Engineer at Softway Pty Ltd.

Working on Gelato, the project to make IA64 Linux rock!

Principal Research Engineer with NICTA and Conjoint Senior Lecturer at UNSW.


Principal Research Engineer with Data61, CSIRO and adjunct senior lecturer at UNSW

NICTA was merged with CSIRO's Digital Productivity group to form Data61. I continued to do more-or-less the same things in Data61 as I did in NICTA.
I work within NICTA as an open-source advocate, project leader, and domain expert in Linux and Open Source. I also hold a position as adjunct Senior Lecturer at UNSW, and until 2012 was chairman of the NSW NICTA Workplace Health and Safety consultative committee; between 2012 and 2015 I was the Supervisor for the Emergency Control Organisation for the building.

I had day-to-day management of the Gelato@UNSW team (see GelatoUNSWPeople). The contract with HP to fund gelato@UNSW was renewed twice; and I gained some additional funding from Google for work on Disk Scheduling.

  • Key achievements during this time include
    • Removing the 2TB disk size limit in Linux
    • Attracted over $500 000 in grant money over the time
    • Supervised numerous successful students
    • Best paper award for Itanium: A system implementor's tale at Usenix 2006

    • Fuzzy Penguin award for our work on Ia64SuperPages in Linux

    • Google grant for work on IOScheduling

    • Numerous minor enhancements in the Linux kernel (see the GIT log for details)
    • First prize in Artemis Orchestra competition for the robot clarinet (my work was in musical interpretation). See the Physics@UNSW pages for a short video, and for the code for generating nice MIDI.

I was also secretary of the OH&S Consultation committee for NICTA's Sydney sites, and managed day-to-day a small number of non-Gelato people for the ERTOS group.

I left Aurema in December 2001, to form the Gelato team at the University of NSW. Gelato is a project to improve scalability and performance on Intel's Itanium Processor Family (IA64). One of my first tasks was to hire some more people.
  • During 2002, I worked on removing limitations from Linux's block device layer, allowing very large storage devices (bigger than 2TB) to be used with Linux, even on 32-bit platforms. This work was accepted into the Linux kernel at version 2.5.47. Other projects worked on in collaboration with the Distributed Systems group at UNSW include a framework to allow device drivers for discs and networks, etc., to be run in userspace, and micro-state accounting, which allows fine-grain accounting of where threads spend their time. My role in this position also included promoting the Itanium Processor Family and the Gelato federation; setting up and maintaining the Gelato@UNSW and the websites, and a certain amount of systems administration.

    In 2003, I changed my 30 hour-per-week Gelato position to a 16-HPW part time one, and took on in addition a 14HPW role with NICTA, to oversee Linux-related research within the Embedded and Real Time Operating system programme.

Promoted to Vice President --- Research in 1999. In this newly created position, I had oversight of all research and development, and recommended to the CEO what research should or should not go ahead on technical and commercial grounds;
  • Was a member of the ARMTech (ARMTech is a resource management product for UNIX and Windows computers) Architecture Steering Committee (which evaluates and approves or rejects all changes to the ARMTech product).
  • Established criteria for acceptance/rejection of research proposals, for tracking progress, and for inter-group communication.
  • Directed research on resident set size control and on virtual memory controls for ARMTech.
  • Acted as domain knowledge expert for all other groups in Aurema in areas of locking, multithreading, interrupts, kernel portability and related areas.
  • Ported ARMTech to Linux on IA64; ported ARMTech to Linux 2.4; both as `skunkworks' projects.
  • Interviewed and evaluated candidates for recruitment.
  • Specified machines for employees to work with at home.
  • Reviewed contracts, specifications, code and documentation for correctness, feasibility and consistency with policy and with other documents.
  • Liaised with organisers for 2001 (Aurema was principle sponsor).

  • Co-supervised a PhD student at the Basser department of Computer Science at Sydney University.
  • Presented part of a course in advanced distributed systems at UNSW.
Promoted to Senior Software Engineer.
  • Specified a test methodology for Softway to use for its kernel products, based on P1003.3. Designed a framework to perform automated tests.
  • Devised user-mode techniques for checkpoint-restart to allow proof-of-concept without access to kernel or library source.
  • Was system architect, analyst and designer for the `Hibernator' project; a 12-person 7 year project to provide kernel-mode process checkpoint/restart under UXP/M (UXP/M is a trademark of Fujitsu.) and IRIX (IRIX is a trademark of SGI.). I was project manager for phases three through six.
  • Set up a bug-tracking system using GPLed software (gnats); specified changes to allow gnats to track changes to source files in response to bugs; supervised the programmer who made the changes.
  • Extended the debugger SDB to allow multi-threaded processes to be debugged.
  • Ported the Java 1.1 runtime classes to Guava, Softway's home-grown Java virtual machine.
  • Ported the Retix X.25 protocol stack to run on Stallion's embedded streams processor.
  • Ported Ingres to Irix 6.2 in less than half the time allowed in the project plan.
  • Worked as consultant with Philips Australia on their `NetCaptain' cable internet project.

  • Worked as consultant with Whitesmiths Australia on Optus's prepaid mobile phone system, and on their mobile-phone activation system.
  • Helped form and was member of Softway's Quality committee, to review, test and approve the first Quality manual and procedures.
joined Softway Pty Ltd as a Software Engineer.
  • Developed and presented courses in C programming, Shell Programming, UNIX Systems Administration, Introduction to UNIX.
  • Presented courses in Object-Oriented Software Engineering and SCO UNIX Systems Administration.
  • Developed a driver for a new ESDI disc controller for Bull HN, as lead engineer in a team of two, for SCO Xenix and for Kodak's `Interactive' flavour of UNIX.

Organisations and Outside Positions

Family, Hobbies and Recreations

I'm married and have two young daughters. My main activities, apart from looking after my daughters, are early music (I sing, play recorders, clarinet, piano and guitar, all rather badly; and am a contributor to the GNU Music project (mutopia and lilypond)), reading, amateur radio (I hold licence VK2FPC), bushwalking, Photography, Mexican and Thai cooking, and wine-tasting.
