Overview

Welcome to the GPU users group at Princeton University! This group is a special interest group intended to be a resource for those involved in general-purpose computing on graphics processing units (GPGPU) on campus. By bringing together GPU users and enthusiasts from different domains, the group hopes to potentially find solutions applicable to other domains, share knowledge and keep updated with the newest technology.

Its first meeting was held on Oct 9, 2012 and was attended by 18 people, mostly graduate students, postdocs and research staff from seven academic departments, namely Chemical & Biological Engineering, Computer Science, Ecology & Evolutionary Biology, Electronic Engineering, Geosciences and Physics as well as Princeton Plasma Physics Laboratory. These research groups are currently utilizing GPU computing to enable their respective research.

The Princeton Institute for Computational Science & Engineering (PICSciE) is fully supportive of this group. It will help by providing resources and training as well as inviting speakers and experts in GPU computing.

Meeting Schedule

The second GPU users group meeting will be held on Tuesday, November 6 at noon in the Visualization Lab, 346 Lewis Library. Lunch will be provided.

Tentative Agenda:

1) Bei Wang presentation and Q&A (15 minutes) Title: Gyrokinetic Particle in Cell (PIC) Simulations on GPU

2) What specific technology/topics would you like to see included in the future training?

3) "Un-meeting" session (participants propose discussion items)

Events

GPU Computing Workshop with NVIDIA, Dates & Location TBD
