Funeral Practices in Upper Northeast Adams

In 1994 in upper north-east Adams county, local people relate thoughts of death with advanced age, hospitals, and nursing homes. Occasionally, there is an accident or irreversible medical problem involving a younger person. These infrequent occurrences receive much attention from the community. Widespread fear of infant mortality is not manifest. However, in this same area, from colonial times until about 1920 death occurred in a more widely dispersed fashion: far from being merely the prospect of the elderly, death\u27s inevitability was the unseen companion of young and old alike. Death could occur at random. Mortality was a distinct possibility for every child. The cultural effects of the ensuing, profoundly different perspective are evidenced in the area\u27s music, art, and folk beliefs. [excerpt

Southwesterly Town Lot Histories of Fairfield, Pennsylvania

Each lot history give the original lot number, original owner, the current address, the owner of the lot in 1860, a description of the lot or dwelling in 1860, a recital of ownership with as much detail as is known, a comprehensive lot history, any known residents in 1860 (may be different than lot owner), and any family notes on any residents mentioned in the lot history. The research is comprehensive, but not necessarily exhaustive. Thorough information for all lots was not always available to the researcher

Standing together for reproducibility in large-scale computing: report on reproducibility@XSEDE

This is the final report on reproducibility@xsede, a one-day workshop held in conjunction with XSEDE14, the annual conference of the Extreme Science and Engineering Discovery Environment (XSEDE). The workshop's discussion-oriented agenda focused on reproducibility in large-scale computational research. Two important themes capture the spirit of the workshop submissions and discussions: (1) organizational stakeholders, especially supercomputer centers, are in a unique position to promote, enable, and support reproducible research; and (2) individual researchers should conduct each experiment as though someone will replicate that experiment. Participants documented numerous issues, questions, technologies, practices, and potentially promising initiatives emerging from the discussion, but also highlighted four areas of particular interest to XSEDE: (1) documentation and training that promotes reproducible research; (2) system-level tools that provide build- and run-time information at the level of the individual job; (3) the need to model best practices in research collaborations involving XSEDE staff; and (4) continued work on gateways and related technologies. In addition, an intriguing question emerged from the day's interactions: would there be value in establishing an annual award for excellence in reproducible research? Overvie

The Life and Impact of Daniel Alexander Payne

On Washington Street, across from McKnight Hall and adjacent to the Intercultural Resource Center, a sign stands in commemoration of the life and accomplishments of an African American who studied at the seminary from 1835 to 1837. The plaque reads: Daniel Alexander Payne (1811-1893). Born a free African American. He taught the colored people at this college, 1837, while a student at the Lutheran Seminary. A historian, he was elected bishop of the AME Church, 1852, and was president of Wilberforce University, 1863-76. What Payne was able to achieve in his life is matched by few of his contemporaries considering the fact that he was a black who grew up in Charleston, South Carolina. Believing that he was ordained by God, he became an educator and an ordained minister. Later in his life, Payne became the first African American president of a college when the African Methodist Church bought Wilberforce University in 1863. Daniel Payne, with his intellectual ideas, influenced the policy of the AME Church for years to come. The Gettysburg College Intercultural Resource Center claims that Pennsylvania College’s acceptance of Daniel Payne was “the first step at addressing cultural diversity at Gettysburg College.” Payne’s personal ambition and his influence in both the abolition movement and the education of black Americans present an example of a model citizen.

Report on the Second Workshop on Sustainable Software for Science: Practice and Experiences (WSSSPE2)

This technical report records and discusses the Second Workshop on Sustainable Software for Science: Practice and Experiences (WSSSPE2). The report includes a description of the alternative, experimental submission and review process, two workshop keynote presentations, a series of lightning talks, a discussion on sustainability, and five discussions from the topic areas of exploring sustainability; software development experiences; credit & incentives; reproducibility & reuse & sharing; and code testing & code review. For each topic, the report includes a list of tangible actions that were proposed and that would lead to potential change. The workshop recognized that reliance on scientific software is pervasive in all areas of world-leading research today. The workshop participants then proceeded to explore different perspectives on the concept of sustainability. Key enablers and barriers of sustainable scientific software were identified from their experiences. In addition, recommendations with new requirements such as software credit files and software prize frameworks were outlined for improving practices in sustainable software engineering. There was also broad consensus that formal training in software development or engineering was rare among the practitioners. Significant strides need to be made in building a sense of community via training in software and technical practices, on increasing their size and scope, and on better integrating them directly into graduate education programs. Finally, journals can define and publish policies to improve reproducibility, whereas reviewers can insist that authors provide sufficient information and access to data and software to allow them reproduce the results in the paper. Hence a list of criteria is compiled for journals to provide to reviewers so as to make it easier to review software submitted for publication as a “Software Paper.

An efficient and portable SIMD algorithm for charge/current deposition in Particle-In-Cell codes

In current computer architectures, data movement (from die to network) is by far the most energy consuming part of an algorithm (10pJ/word on-die to 10,000pJ/word on the network). To increase memory locality at the hardware level and reduce energy consumption related to data movement, future exascale computers tend to use more and more cores on each compute nodes ("fat nodes") that will have a reduced clock speed to allow for efficient cooling. To compensate for frequency decrease, machine vendors are making use of long SIMD instruction registers that are able to process multiple data with one arithmetic operator in one clock cycle. SIMD register length is expected to double every four years. As a consequence, Particle-In-Cell (PIC) codes will have to achieve good vectorization to fully take advantage of these upcoming architectures. In this paper, we present a new algorithm that allows for efficient and portable SIMD vectorization of current/charge deposition routines that are, along with the field gathering routines, among the most time consuming parts of the PIC algorithm. Our new algorithm uses a particular data structure that takes into account memory alignement constraints and avoids gather/scatter instructions that can significantly affect vectorization performances on current CPUs. The new algorithm was successfully implemented in the 3D skeleton PIC code PICSAR and tested on Haswell Xeon processors (AVX2-256 bits wide data registers). Results show a factor of $\times 2$ to $\times 2.5$ speed-up in double precision for particle shape factor of order $1$ to $3$. The new algorithm can be applied as is on future KNL (Knights Landing) architectures that will include AVX-512 instruction sets with 512 bits register lengths (8 doubles/16 singles).Comment: 36 pages, 5 figure

How do particle physicists learn the programming concepts they need?

The ability to read, use and develop code efficiently and successfully is a key ingredient in modern particle physics. We report the experience of a training program, identified as "Advanced Programming Concepts", that introduces software concepts, methods and techniques to work effectively on a daily basis in a HEP experiment or other programming intensive fields. This paper illustrates the principles, motivations and methods that shape the "Advanced Computing Concepts" training program, the knowledge base that it conveys, an analysis of the feedback received so far, and the integration of these concepts in the software development process of the experiments as well as its applicability to a wider audience.Comment: 8 pages, 2 figures, CHEP2015 proceeding
