ARC begins pilot consulting service for scientific code optimization

By | General Interest, News | No Comments

ARC is starting a pilot consulting service aimed at scientific code optimization.

Through this service, you can receive assistance with locating performance bottlenecks, identifying hot spots, and parallelizing performance-critical parts of your HPC codes. Projects will be handled on a first-come, first-served basis, and assistance is limited to approximately 6 hours per project.

Please contact Alexander Gaenko <galexv@umich.edu> to set up a consultation appointment.

Climate Modeling: What To Do While We Wait for Exascale

3:30 – 4:30 p.m., Thursday, Feb. 5
Room 2246, Space Research Building

Cloud processes play a central role in the dynamics of the tropical atmosphere, but for many years the shortcomings of cloud parameterizations have limited our ability to simulate and understand important weather systems. Since about 2001, “super-parameterization” has emerged as a new path forward, complementing but not replacing conventional approaches. This talk will outline the method, summarize its strengths and limitations, and show some recent results, including climate change simulations.

This event is presented by the Department of Atmospheric, Oceanic, and Space Sciences, and the Michigan Institute for Computational Discovery and Engineering.

ICPSR Summer Undergraduate Internship Program accepting applications — Jan. 31 deadline

By | Educational, Events | No Comments

The ICPSR summer internship program provides undergraduate students with a unique and expansive research experience that introduces all aspects of social science research and includes supported exploration of a research query from start to finish, data management training, and focused methodological education in quantitative research. This prepares interns for capstone or senior thesis projects, graduate school, and/or research-based employment opportunities. The students, under the supervision of faculty mentors, develop a research question, perform a literature search and review, complete data analysis, and report findings in a poster; learn good data management processes and research practices with a research process mentor; and attend classes at the ICPSR Summer Program in Quantitative Methods.

Applications are being accepted through Jan. 31. Visit the internship website for more information.
