At the recent Computer Supported Cooperative Work Conference in San Francisco, Nan-Chen Chen presented the paper, “Considering Time in Designing Large-Scale Systems for Scientific Computing”. In this ethnographic study, Nan-Chen and her co-authors, Sarah Poon, Lavanya Ramakrishnan, and Cecilia Aragon, make the case that temporal rhythms and collective time should be more carefully considered in the design of high performance computing systems.
