Consider TeraGrid resources, with CAC support!

While the Flux Project (http://cac.engin.umich.edu/resources/systems/flux/index.html) is a major improvement in the availability of HPC resources on campus the CAC would like to mention other HPC resources available to researchers.

TeraGrid (www.teragrid.org) is a free HPC resource funded by NSF. Awards of CPU time are granted to researchers who request them on a wide collection of resources.

TeraGrid grants most requests with some sort of an award. There are two award types:

  • Startup/Education (200,000 CPU Hours or less)
  • Research Allocations (Up to Unlimited CPU Hours)

The CAC provides tools to TeraGrid users to interoperate between Flux and TeraGrid resources and supports users of TeraGrid on campus.

Those interested in applying for TeraGrid time should see: http://cac.engin.umich.edu/resources/teragrid/

You can also contact the CAC with questions or for a presentation at cac-support@umich.edu


					

Blue Waters Undergraduate Petascale Internship Program: Application deadline 3/31

Who:

Shodor (A national resource for computational science education) is actively recruiting undergraduate faculty and students:

  • Undergraduate faculty who would like to mentor an undergraduate student in a year-long internship in the sciences, engineering, or mathematics that involves teaching or researching the use of high-performance computing in studying problems in these fields.
  • Undergraduate students interested in participating in a year-long science or engineering internship. Students must be enrolled as undergraduates through Spring 2012 at a U.S. degree-granting institution.

What:

Support is provided by the NSF-funded Blue Waters Project for sustained petascale computing to support year-long undergraduate internship experiences involving the application of high-performance computing to problems in the sciences, engineering, or mathematics. The program provides a student stipend totaling $5000, a two-week intensive high-performance computing workshop, and travel to the SC11 supercomputing conference in Seattle.

This program provides support for undergraduate internship activities at any accredited degree granting institution in the United States. The internships awarded through this program may be to students working with a faculty mentor on their home campus, or at another campus. Interested faculty need to create a position description through our site, and can specify a particular student that the position is intended for, or may select a qualified applicant with Blue Waters support through our program.

Promotional Material:

PowerPoint slide is available to let students know about the program (if your browser or e-mail client appends a “.doc” suffix to this file, you will need to remove that suffix to open the file with PowerPoint). In addition, poster-sizedand handout-sized flyers are available (in pdf format) to inform students and colleagues about this program.

When:

Student applications and intern position descriptions from faculty must be submitted by March 31, 2011. Be sure to click the “Submit” button at the bottom of the web form to be entered into our system. Review and selection will be conducted in early April, with notifications being made by April 15.

A two-week workshop will be held May 29 through June 10. Interns are expected to work full-time over the Summer, and as their schedule allows during the academic year. Work plans will need to be arranged by the student and faculty mentor, and approved by the Blue Waters Undergraduate Petascale Education Program.

How:

Through our website:

  • Faculty should create descriptions of undergraduate internship positions they have available, indicating either that the position is intended for a particular student applicant, or that it is open to qualified applicants.
  • Eligible undergraduate students are asked to submit an application for consideration. There is an area on the form where students can identify a faculty member as a mentor. Students who have taken the initiative to arrange an internship with a faculty mentor are more likely to be selected for this program than students that have not.

Scientific Computing Seminar 3/9: Nick Trefethen demos Chebfun

Special Scientific Computing Seminar

Wednesday, March 9, 12-1pm, 1005 DOW
Sponsored by:  UM Institute for Computational Science and Engineering (ICSE) http://www.icse.umich.edu/

Nick Trefethen, Professor of Numerical Analysis, Oxford University

“Computing with Chebfun”

Anyone who uses Matlab will enjoy Chebfun, a freely-available package that overloads Matlab’s familiar operations on vectors to apply to functions of a continuous variable. Thus in Matlab, SUM(f) adds up the entries of a vector, but in Chebfun, it computes the integral of a function. MAX(f) finds the maximum, ROOTS(f) finds the roots, and so on. Under the hood, everything is based on piecewise expansions in Chebyshev polynomials, but in principle you don’t need to know that.

This talk will be a hands-on demonstration, and attendees are welcome to bring a laptop running Matlab if they want try Chebfun on the spot. Just as Chebfun turns vectors into functions, it turns matrices into operators, notably differential and integral operators. One of our proudest achievements is that we’ve overloaded Matlab’s backslash command to solve linear and nonlinear differential equations, typically to close to machine precision in a fraction of a second.

Video of this seminar will be linked from this blog after the event.
