    Abstract:

    Scientists using workflows often have access to both High Performance Computing and High-Throughput Computing sites, but HPC sites’ architecture is less conducive to HTC paradigms. The choices of middleware and site can have drastic performance differences on different workflows. To explore these differences, we created tools to expand Makeflow and Work Queue’s capabilities. We then performed four speed of light tests, testing job dispatch rate, data delivery from the master to worker…

    Abstract:

    In recent scholarship, moral theologians and readers of Thomas Aquinas have shown increasing sensitivity to the role of the passions in the moral life. Yet these accounts have paid inadequate attention to Thomas’s writings on Christ’s passions as a source of moral reflection. As I argue in this essay, Thomas’s writings on Christ’s human affectivity should not be limited to the concerns of Christology; rather, they should be integrated into a fuller account of the human passions. One upshot of…

    Abstract:

    Philosopher Harry Frankfurt has famously coined “bullshit” as a technical term— it refers not to outright lying but rather to a casual indifference to truth. Disregard for truth is accepted and even expected in many contexts, yet it creates conditions for gross injustice and dehumanization. I offer an account of widespread cultural indifference to truth as structural sin, a condition I call “truth indifference.” Drawing on Thomas Aquinas’s understanding of the virtue of truth (veracitas), I m…

    Abstract:

    In this article, I argue that Immanuel Kant fails to provide a satisfactory account of ‘moral debt’ in Religion within the Boundaries of Mere Reason. More precisely, he fails to answer the question of why we should assume that a debt exists in the first place. In light of recent scholarship on this area of his thought, I sketch some possible readings of Kant on the nature of moral transformation that suggest how he might account for this debt. I then argue that these accounts fail to justify …

    Abstract:

    Neural networks have been shown to improve performance across a range of natural-language tasks. However, designing and training them can be complicated. Frequently, researchers resort to repeated experimentation to pick optimal settings. In this paper, we address the issue of choosing the correct number of units in hidden layers. We introduce a method for automatically adjusting network size by pruning out hidden units through L∞,1 and L2,1 regularization. We apply this method to language mo…

    Abstract:

    Computational reproducibility depends on being able to isolate necessary and sufficient computational artifacts and preserve them for later re-execution. Both isolation and preservation of artifacts can be challenging due to the complexity of existing software and systems and the resulting implicit dependencies, resource distribution, and shifting compatibility of systems as time progresses—all conspiring to break the reproducibility of an application. Sandboxing is a technique that has bee…
