INF5063 Asymmetric Multicore Challenge 2011
The Asymmetric multicore challenge is a competition open for students in the INF5063 course. Each contestant compete in encoding the tractor video as fast as possible on the GPU and the Cell Broadband Engine. Contestants may submit an entry to one or both architectures. Entries are delivered by a group consisting of up to two students.
Rules:
- Both GPU and Cell entries are eligible and will be judged separately.
- Submit your entry to inf5063@ifi.uio.no
- Encoded video must not deviate significantly from the reference encoder (precode). This includes both output file size and subjective video and prediction quality. Failure to comply will result in a time penalty. If your are unsure if your entry will incur a penalty, send us a version in advance for assessment.
- Results will be announced in the session on December 15th, and both the winner of the GPU architecture and CBE architecture competition will be awarded.
- Entries will be benchmarked on adams.ndlab.net (GeForce GTX 580) and standard PS3s.
- Cell entries will be tested with foreman, GPU entries tested with tractor.
- Motion estimation and other algorithms may be changed, e.g. with diamond search or FastDCT as long as the following satisfied:
- The prediction buffer is of similar quality as the reference code
- Motion estimation range and cut-off is the same as the reference
- Motion estimation is performed for all macroblocks and channels
- If unsure, ask us (or incur penalty)
- Quality parameters should be the same as in precode.
To check if the output video quality differs from the reference implementation, you can use the psnr-script included in the mplayer source.
Register for the competition by noon, Monday 12th by sending us an e-mail. Include your t-shirt size (which is not the main prize). :)
Deadline for competition entry submission is by noon, Wednesday 14th.
