CUDA vs. OpenCL

Based on attendee interest, we'll have a meeting devoted to the pros and cons of CUDA and OpenCL. Rather than a head-to-head debate, we'll aim to have presentations addressing the strengths of each and an introduction to what the programming is like.


Given the multitude of methods available for writing CUDA and OpenCL code, I'd like to encourage all members to consider offering a brief introduction (2 or 3 slides) of their use of CUDA or OpenCL. I think this will give us a good feeling for the pros & cons of using these APIs in practice. It will also give us all a chance to learn about libraries and methods we might not be aware of. Please contact Eliot to be one of the speakers.

Proposed Agenda:

6:00-6:30pm Introductions & Current Events - We'll review the announcements from AMD's Fusion Developer Summit. Attendees are encouraged to tell us a bit about themselves or mention any news we've overlooked.

6:30-7:30pm CUDA Intro with Pros & Cons - Eliot Eshelman

7:30pm-8:30pm OpenCL Intro with Pros & Cons - Ken Domino and Dmytro Konobrytskyi

Microway will provide pizza.

    For folks who may be interested...my presentation (cleaned up, of course) is at http://codinggorilla.domemtech.com/code/pros-and-cons-of-opencl-updated.pdf ;a comparison of OpenCL and CUDA is at http://codinggorilla.domemtech.com/?p=669 ; and, a comparison of OpenCL, CUDA, and C++ AMP performance is at http://codinggorilla.domemtech.com/?p=1135

    very informative. I would like to know if anyone in the group has good knowledge of Thrust to present at a future meetup.

    Presentations were poor, and did not really get into the differences between the two languages.

    Good presentations and questions, ... and as always, the pizza and the NERD center. Always good to get different perspectives and see what people are doing, which forces me to follow up on things I haven't looked at yet.

    Excellent! Interesting talks on developer experiences. Great technical discussions from knowledgeable practitioners. Learned a lot in one evening. Thanks presenters, Eliot, Microway, and MS Nerd.

    Perhaps the topic threatens to become a religious war, but I think we did a good job staying balanced. I enjoyed hearing project specifics from group members, and I hope to see more members discussing their work.
