- Technologies used: Sun Workshop (C++) 4.2/6.2 Solaris, gcc 3.2.3/3.4.6/4.1.2 Linux, VxWorks 2.x PPC603, Perl, make, gmake, clearmake, csh, tcsh, ObjectStore, UnitTest++, YACC++, gdb, dbx, TotalView, valgrind, purify, quantify- Developed a memory allocation wrapper that logs memory allocations/deallocations, memory painting, padding creation/checking, improper reallocations/frees/deletes for debugging of memory corruption problems.- Designed a GCC extension to auto-generate code that contains information about types and functions compiled so that the contents of shared libraries could be used programmatically.- Debugging of complex multi-threaded, multi-process problems including issues with shared memory, memory corruption, stack corruption, compiler bugs, volatility issues, including debugging into the underlying ASM code when needed.- Worked on a port of the company’s code base (over 5 million lines of code) from SPARC/Solaris to x86/Linux. Including the design of code to handle the endian problems for the ongoing use as a cross-platform package. Also worked on several ports between major compiler versions.

- Created a Linux 2.4.x/2.6.x VME Driver for a Solflower VME bridge from parts of non-functional open source drivers for other cards that use the Universe II chipset. Worked with Solflower’s hardware engineers to develop a byte-swapping strategy to allow easier interchange between x86 and a large body of memory mapped proprietary big-endian VME devices.- Helped implement and design a cross process shared memory allocator along with extensions to improve debugging- Analysis (with quantify and other home grown tools) and refactoring of runtime critical code as a part of a customer requested speedup project. Accomplished over 30% speedup on average, the customer requirement had been 20%.- Extended and maintained a lazy-evaluation model caching expression system. Changes resulted in over 1000x speed improvement in some cases. Extended the error processing to provide meaningful errors as well as the exact location in the string for the error. Refactored pieces to cut down on code duplication as well as make the behavior fully uniform within the system.- Developed an embedded system on PPC603/VxWorks to do distributed capture and processing of data. This included working directly with hardware engineering for hardware integration with proprietary hardware and developing an cross-platform RPC interchange for complex C++ data via sockets in a runtime critical environment.

I worked as a tutor for Engineering and Software courses, and then I set up LabView for the physics department. During this time I presented a paper at the Virtual Instrumentation in Education (1997) conference held at MIT.

I worked part time doing office work, copying/collating/assembling of literature. I also did through-hole circuit board assembly during the summer.
