Flipped class energizes CFD

By Mark Dwortzan Two . . . one . . . zero. Change! Clutching an iPhone, Assistant Professor Lorena Barba (ME) works a brightly lit computer lab at the Photonics Center like a Hollywood movie director, cueing her ENG ME 702—Computational Fluid Dynamics (CFD)—students to take their places on the set of what she calls...

Barba receives NSF CAREER award

Barba-Lorena-2011

The award will fund Prof. Barba’s research in scalable algorithms for extreme computing on heterogeneous systems. Recent trends in high-performance computing (HPC) are clearly in the direction of computing systems involving various structurally different types of hardware (i.e., heterogeneous), of which a prominent example are GPUs (graphics processing units). Prof. Barba is one of the early adopters of GPU... Continue »

Barba awarded computer center grant

The Massachusetts Green High Performance Computing Center (MGHPCC) is a ground-breaking collaboration of five of the state’s most research-intensive universities, state government and private industry—the most significant such collaboration in the history of the Commonwealth.

Prof. Barba led a multi-institution bid to success in the call for research seed grants of the Massachusetts Green High-Performance Computing Center, MGHPCC. The award amounts to $130,487 for the duration of one year. This project is a collaboration among investigators in BU, Harvard and UMass aimed at creating an open and high-performance software infrastructure... Continue »

New paper published: CiSE journal

The Roofline model relates floating-point performance, operational performance and memory performance. This model distinctly quantifies the high operational intensity of fast N-body algorithms and reveals their advantage on many-core architectures.

A new paper authored by Rio Yokota and Lorena Barba has appeared (published online 3 Jan. 2012) in Computing in Science and Engineering, the joint publication of the IEEE Computer Society and he American Institute of Physics. This paper presents a new hybrid treecode/FMM formulation that has been implemented in the ExaFMM code, recently released... Continue »

Digital pedagogy in three parts

The digital pedagogy in this course stands on a tripod. One leg is class presentation, recording and online dissemination. The second leg is a course blog, with student assignments publicly available. The third leg is a program of distinguished speakers participating in the course via Skype.

Screencasting, course blog, remote guests — This course is one of a set of ten modules in the College of Engineering’s offerings under the Introduction to Engineering umbrella. All incoming freshmen have to choose two modules, according to their interests, with topics varying from mechanical design, photonics, biomedical engineering environments, among others. This module is... Continue »

BU's top provider of educational media

Prof Barba has single-handedly become the university’s top provider of educational media via iTunes U.

With her latest course on iTunes U, a freshman Introduction to Engineering module titled “Bio-Aerial Locomotion,” Prof. Barba firmly establishes her track-record of using new media to support learning and championing the open courseware movement. This course has been the Top Collection on BU’s iTunes page since the start of the semester, while her previous courses... Continue »
