  • GOTOHELL.DLL: Software Dependencies and The
    GOTOHELL.DLL Software Dependencies and the Maintenance of Microsoft Windows Stephanie Dick Daniel Volmar Harvard University Presented at “The Maintainers: A Conference” Stephens Institute of Technology, Hoboken, NJ April 9, 2016 Abstract Software never stands alone, but exists always in relation to the other soft- ware that enables it, the hardware that runs it, and the communities who make, own, and maintain it. Here we consider a phenomenon called “DLL hell,” a case in which those relationships broke down, endemic the to Mi- crosoft Windows platform in the mid-to-late 1990s. Software applications often failed because they required specific dynamic-link libraries (DLLs), which other applications may have overwritten with their own preferred ver- sions. We will excavate “DLL hell” for insight into the experience of modern computing, which emerged from the complex ecosystem of manufacturers, developers, and users who collectively held the Windows platform together. Furthermore, we propose that in producing Windows, Microsoft had to balance a unique and formidable tension between customer expectations and investor demands. Every day, millions of people rely on software that assumes Windows will behave a certain way, even if that behavior happens to be outdated, inconvenient, or just plain broken, leaving Microsoft “on the hook” for the uses or abuses that others make of its platform. Bound so tightly to its legacy, Windows had to maintain the old in order to pro- mote the new, and DLL hell highlights just how difficult this could be. We proceed in two phases: first, exploring the history of software componenti- zation in order to explain its implementation on the Windows architecture; and second, defining the problem and surveying the official and informal means with which IT professionals managed their unruly Windows systems, with special attention paid to the contested distinction between a flaw on the designer’s part and a lack of discipline within the using community.

In these computing platforms, each computing node consists of a multicore, an accelerator, and a complex memory hierarchy, which are connected to other nodes using a variety of high-performance networks. Up to now, researchers have been using cycle-accurate simulators to evaluate the performance of computer systems in detail. However, the execution of the simulators, which models modern computing architecture for multi-core, multi-node, datacenter, memory hierarchy, new memory, and new interconnection, is too slow and infeasible; since the architecture has become more complex today, the complexity of the simulator is rapidly increasing. Therefore, it is seriously challenging to employ them in the research and development of next-generation computer systems. To solve this problem, we previously presented EPSim (Epoch-based Simulator), which defines epochs that can be run independently by dividing the simulation run into several sections and executes them in parallel on a multicore platform, resulting in only the limited simulation speedup.
