  5. 5. RUSSELL JOHN CHILDS – RESUME ADDENDUM DETAILED PROFESSIONAL AND ACADEMIC HISTORY Microsoft Corporation SDE II 2008-2009 Primary responsibilities: 1. Undertook debugging and maintenance of code base, build optimisation, query latency reduction. 2. Development of a load-balancing algorithm for query distribution across Bing services. 3. Statistical modeling of counters. Advantest, Santa Clara, CA Senior Software Engineer 2002-2004 Primary responsibilities: 1. Developing architecture for framework permitting integration of C++ or Verilog models of ATE hardware modules. Framework utilised concept of events to notify different components of system activity. Event traffic was coordinated by the framework allowing models to communicate through event notifications. Cyclisation was regarded as a specialised type of event handling in which a rising or falling clock edge occurred at regular intervals and could be ignored by unregistered components alleviating the problem of expensive calls across the PLI layer. Interrupts became a seamless component of the methodology. 2. Developing methodology for streamlining requirements management replacing existing ad hoc and informal requirements control. Identified replicated, redundant and conflicting requirements moving company toward CMMI3 compliancy. Company was disinclined toward use of commercial tools such as Requisite Pro necessitating a strategy to be developed that had minimal impact on existing processes. To this end a spreadsheet was used into which cross-referenced requirements were entered, maintained, categorised and validated for acceptance or rejection. Proposals were made for a best practice procedure for submission and review of new requirements. CMMI compliance was made mandatory by the customer, which approved and welcomed the strategy adopted. 3. Performing integration testing of multiple class base and developing a framework for automation of testing of all parameters in all classes such that normal, boundary and error cases were exhaustively covered. Testing was performed in-vivo on objects whilst they were in use in their system, rather than in-vitro as standalone objects. 4. Developing framework for unit testing of individual classes 5. Writing technical user guides and specifications reversed engineered from class code. Defined Open Standards from BNF specifications, class interfaces and tester opcodes. Advising company on pitfalls of reverse engineering and mechanisms for mitigating against proprietary creep into open architecture standards. Sun Microsystems, Menlo Park, CA Member of Technical Staff 2000-2002 Primary responsibilities: 1. Leading the development of a behavioural model for a rapid address/data switch ASIC: To improve the performance of system simulations of hardware components, models were developed to act as fast surrogates for the hardware. Verilog RTL was used to synthesise the processor hardware and the models comprised a fast C++ Core wrapped by a thin Verilog layer. The Core implemented the behavioural emulation of the hardware whilst the Verilog wrapper provided a pin compatible
  6. 6. interface to the rest of the hardware system. This provided for direct, transparent substitution of the model into the hardware environment. The Verilog wrapper invoked the C++ Core at each clock cycle, unless the Core sent notification of inactivity. The PLI layer accommodated communication between the Verilog and the C++ for which I devised an efficient protocol. Events received by the Verilog, such as network traffic packets or requests to access registers, were conveyed directly to the Core through this protocol. The results of processed events were also communicated back to the Verilog wrapper through the protocol. The C++ Core comprised a set of base classes, which were reusable across different ASICs, and a set of final layer classes specific to the ASIC being modelled. The principal functionality of the base classes was to provide automatic registration and boot-strapping of active Core components across clock cycles (between which the Core went out of scope), strictly controlled resource management, arbitration during resource contention and controlled access to system registers. The final layer classes were specific to the switch ASIC and processed incoming network traffic, routed it to destination clients, processed parity and unrecoverable errors and implemented network traffic flow and freeze control. An object oriented design methodology was undertaken in which components were decoupled to allow for individual replacement, in the event of changes to the hardware being modelled, with minimal impact on the remaining architecture. The model was event driven and run-time configurable to represent any chip in the network, upon instantiation. Clock edges were treated as generic events and asynchronous interrupts were handled seamlessly. The reusable components used messaging to determine the runtime behaviour resulting from events spawned by clock edges and interrupts. For example, an arbiter component could me made to use a round robin or an alternative scheduling scheme according to messages received. To conserve memory and improve performance only the active sections of the network and active parts of active chips were represented within a given clock cycle. The collective behaviour of active model components provided the emulation of routing of network traffic and the observance of protocols, such as cache coherency, in the hardware. Function templates and a recurring template pattern were used to eliminate most runtime polymorphism, increasing performance and type safety. Model component classes were strongly decoupled and utilised fast, direct messaging to facilitate communication. New types could be added to the system without recompilation of existing code. 2. Leading the design and development of a template class pre-processor and library for Vera. Vera was used by verifiers to exercise features of the hardware prior to fabrication. To provide greater ease of usage and introduce greater OO design flexibility I developed a pre-processor lexical extension allowing template classes syntax to be processed into strongly typed Vera classes, upon instantiation. The use of the pre-processor enabled template class syntax to be incorporated into Vera code non-invasively. This prevented interference with compiler and debugger error line reporting. Building upon the capabilities of the pre-processor extension I designed a Vera template class library that mirrored a subset of the C++ Standard Template Library. The Vera template class library comprised a set of strongly typable container classes, self-validating data-type classes, with automatic serialisation, and event handler classes including timer and messaging classes. The foundation for the container classes was a highly optimised augmented binary tree class with additional pointers providing linked list nodes. This offered dual and simultaneous capabilities as a binary tree, providing searches, insertions, deletions and linear indexing of log ( ) 2 O size in time and a sorted linear linked list allowing for fast copying to an array for linear traversal and linear time rebalancing. This was accommodated through the node structures for the tree. An efficient tree balancing mechanism was implemented and subject to rigorous mathematical proof. 3. Development and implementation of a non-invasive, grey-box, automated and repeatable test strategy for C++ and Vera classes.
  7. 7. To facilitate rigorous testing of C++ and Vera classes I developed a non-invasive test strategy. Wrapper classes, deriving from classes under test (CUTs), contained overridden methods that intercepted and monitored invocations of public and internal methods in the CUTs during program execution by sandwiching calls to the base method between pre and post condition test code.. The wrapper classes replaced the CUTs within real-world code test harnesses designed to test the classes in anger. Test harness operation was governed by a dedicated TestCase class, which provided automated program flow validation and check-pointing, through the wrapper class overrides, together with reporting of test results. The class allowed for precise profiling of class failures under test. Test plans were developed which enumerated the normal, boundary and error cases and provided an operations list detailing coverage of the test cases, predicted program flow and check-point values. The operations list was a description of the test harness implementation. The test strategy was validated, by induction, through the use of the TestCase class to test itself. 4. Additional duties included mentoring, training and supervising an intern on one-year placement together with participation in design reviews as reader and inspector. I undertook the training, in C++ and event driven, object oriented techniques and methodologies, of an intern on placement with Sun. I developed his capacities as a technical software engineer and encouraged independent and lateral thinking. I placed great emphasis on initiative and tenacious, disciplined problem solving. I also placed great emphasis on providing encouragement and team recognition of his accomplishments and contributions during his involvement with behavioural modelling. I supervised his work and quarterly evaluations. As reader and inspector at formal design reviews I enforced rigorous standards in the drafting of hardware design documents. I required that they provide the requisite detail and clarity appropriate to implementation by hardware engineers and modelling and testing by verifiers. EDS, Hook, Hampshire, UK Information Analyst 1999-2000 Primary responsibilities: 1. Development of C++ APIs for local-local, local-remote and remote-remote client file transfers and centralised print services. The development strongly utilised object oriented methodology and the implementation required good knowledge of AIX kernel processes, primarily sockets, named pipes, shared memory and kernel printer protocols. 2. Development of a GUI enabling monitoring of system resources and activity. X-Designer and NetView/6000 were fully utilised during development. 3. Application of ISO 9000 and SIL3 safety standards. Since the development constituted part of the central architecture responsible for providing Air Traffic Control with proximity information, as part of the collision avoidance mechanism for transatlantic flights, strict standards were applied. The development was subject to peer and formal review during design, implementation and unit testing. Strict coding standards were enforced and high levels of coverage testing were formally required. I conducted FMECA hazard analysis on all module inputs and assessed risk levels spanning low severity to catastrophic failure. Rolls-Royce Control Systems, Derby, Derbyshire, UK Analyst Programmer 1998-1999 Primary responsibilities:
  8. 8. 1. Development of algorithms for numerical interpolation of solutions to the neutron transport equation across finite elements of a fission reactor core model. The development of the model was subject to ISO 9000 standards and under contract to the Royal Navy. The core was designed for use in nuclear powered submarines and development constituted part of the Naval Nuclear Propulsion Programme. The algorithms were developed in C and interfaced with nuclear databases through embedded SQL. 2. Development of a graphical user library. The user library was developed to facilitate fast production of graphical applets, for presentation on web sites and at exhibitions, and 3-D data representations. Much of the development required optimised transformation algorithms to provide higher frame rates, curve fitting and surface rendering. 3. General development of database applications in FoxPro 2.6/Visual FoxPro 5 and reviewing of ADA code and design. These duties were undertaken whilst awaiting Secret Atomic security clearance from the MoD. Merlin Distribution, Westbury, Wiltshire, United Kingdom Systems Analyst/Programmer 1996-1998 Principal duties: 1. Development of a route-scheduling algorithm for steel distribution across sites in England, Scotland and Wales. Shipment of steel from production sites in Wales to other parts of the country was subject to manual scheduling. I developed a partial solution to the problem of optimising route scheduling based upon an algorithmic solution to the Travelling Salesman Problem I developed earlier. It produced disjoint routes, each satisfying the Single Travelling Salesman Problem and jointly minimising distance and number of salesmen. Although graph algorithms existed to join these routes, I could not prove analytically that this solved the single TSP. I used sets of towns with known solutions for Monte-Carlo simulations to obtain confidence limits on the optimality of solutions. The algorithm was roughly ( . ) 4 5 time  O n . 2. Development of Visual FoxPro 5 inventory management software. Royal Naval College, Greenwich, London, United Kingdom Senior Lecturer 1991-1993 Principal Duties: 1. Lecturing in nuclear and atomic physics and mathematics. Courses ranged from basic to MSc level. The student body comprised naval officers, submariners, health physicists and dockyard nuclear operators. I had responsibilities for providing training in nuclear theory, special relativity, quantum mechanics and mathematics. The courses were designed to provide training for non-technical personnel and university graduates. Accordingly, I developed an ability to express complex principles in mathematics and physics in a manner allowing for their assimilation by personnel from varying educational backgrounds. I placed heavy emphasis on everyday analogy and providing explanations from a variety of perspectives to accommodate the differences in thinking processes across the student body. I adopted an informal approach in my relationship with my students and encouraged team cooperation within the groups to ensure that all students were assisted in their understanding of the complex lecture material. Much of the tutoring took place out of hours in informal settings to allow non-technical students to be given additional help in understanding the material.
  9. 9. 2. Supervision of student laboratories and field studies. Practical application of nuclear principles took place within student laboratories and industrial application was demonstrated during field trips to nuclear establishments. I supervised laboratory practicals and long term visits to Rolls-Royce and the Dounreay reprocessing and fission fast breeder research complex. 3. Research into the risks and stochastic health effects of nuclear incidents. To ensure safe levels of operation during berthing of nuclear submarines in populated regions the college conducted research into the likelihood, severity and health implications of reactor core breaches. I conducted research into the distribution of fission products released during such incidents, the effects of prevailing weather conditions on particulate and gaseous emissions and the effects of inhalation, ingestion and physical exposure on population groups. Hazard analyses were performed which identified main risks to populations of long term health impairment, incapacitation or death and assessed the likelihood against severity of different categories of nuclear incidents. PhD: Particle Physics, Birmingham University, Birmingham, United Kingdom 12/1990 Lecture courses: Relativistic Quantum Mechanics, Quantum Field Theory, Gauge Field Theory, Unified Field Theory, Superstring Theory, Supersymmetry Theory, General Relativity and Theoretical Particle Physics. Research: Identification of exotic gluonium states, glueballs, produced in 300 GeV/c proton-proton collisions. Conducted partial wave analysis and meson spectral mass determination through least square and maximum likelihood fits to Gaussian, Breit-Wigner, Weibull and Granet phase-space background distributions. Potential candidates were identified through their quantum signatures and subject to deeper analysis of production cross-sections, decay branching ratios and angular decay distributions. Experimental: Undertook complete supervision of a large, medium grain and a small, high grain  photon calorimeter prior to and during data runs at the CERN facility, Geneva. I calibrated the calorimeters against 0 and 0 mass distributions, determined threshold operational voltage values, improved signal discrimination, and developed pattern recognition algorithms to detect and measure  photon hits, energy deposition and spatial distribution within the calorimeters. I also undertook reduction of raw data to physics data for use in the analysis of the particle interactions giving rise to  production. Monte-Carlo simulations were used to determine the effects of calorimeter geometry together with spatial and energy resolution on detector efficiency. Known particle decays were simulated according to branching ratio and random orientation and used to determine the average  detection efficiency of the calorimeters. BSc: Physics, Liverpool University, Liverpool, United Kingdom 07/1985 Lecture Courses: Special Relativity, Quantum Mechanics, Particle Physics, Astrophysics, Low Temperature Physics, Solid State Physics, Atomic Physics, Nuclear Physics, Mechanics, Optics, Wave Mechanics, General Theory, Physics of Nuclear Reactors, Geophysics, Mathematics and Electronics.
