Current advances in High Performance Computing (HPC) increasingly impact efficient software development workflows. Programmers for HPC applications need to consider trends such as increased core counts, multiple levels of parallelism, reduced memory per core, and I/O system challenges in order to derive well performing and highly scalable codes. At the same time, the increasing complexity adds further sources of program defects. While novel programming paradigms and advanced system libraries provide solutions for some of these challenges, appropriate supporting tools are indispensable....

During the Progressive Era, over 150 African American women's clubs flourished in Chicago. Through these clubs, women created a vibrant social world of their own, seeking to achieve social and political uplift by educating themselves and the members of their communities. In politics, they battled legal discrimination, advocated anti-lynching laws, and fought for suffrage. In the tradition of other mothering, in which the the community shares in the care and raising of all its children, the club women established kindergartens, youth clubs, and homes for the elderly.

In recent years, American shoppers have become more conscious of their food choices and have increasingly turned to CSAs, farmers' markets, organic foods in supermarkets, and to joining and forming new food co-ops. In fact, food co-ops have been a viable food source, as well as a means of collective and democratic ownership, for nearly 180 years.

In Food Co-ops in America, Anne Meis Knupfer examines the economic and democratic ideals of food cooperatives. She shows readers what the histories of food co-ops can tell us about our rights as consumers, how we can practice...
