- Our collaborative work with ARM was presented at ARM TechCon'16 (Oct. 27);
- ARM uses CK as a front-end for systematic and reproducible benchmarking and tuning of real workloads: link;
- Open challenges in computer engineering have been updated: link;
- General Motors and dividiti shared CK workflow to crowdsource benchmarking and optimization of CAFFE (DNN framework) here;
- We have moved related Open Science resources here;
This CK-powered open-source Android application lets the community participate in experiment crowdsourcing which require webcam (such as crowd-benchmarking and crowd-tuning Caffe, Tensorflow and other DNN frameworks or any realistic application for image processing and recognition) using their mobile devices (mobile phones, tablets, IoT, etc) and exchange knowledge via public CK servers.
You can download this app from the Google Play Store.
You can also find public results at Live CK repo!
Current scenarios include multi-dimensional and multi-objective optimization of benchmarks and real workloads such as Caffe, TensorFlow and other DNN frameworks in terms of performance, accuracy, energy, memory footprint, cost, etc.

This application requires access to your Camera to let you capture images, recognize them and collect various performance statistics. Note that, by default, no images are sent to public servers! Only if misprediction happens, you are encouraged but not obliged (!) to submit incorrectly recognized image with the correct label to the public server to help the community enhance existing data sets with new images!
