Crowdsourcing experiments 2.4 [free]

This application lets you participate in experiment crowdsourcing to help researchers solve complex problems using open-source Collective Knowledge Engine available at
http://github.com/ctuning/ck . You can see all public crowd results at http://cknowledge.org/repo! You can also check out other ways to participate in experiment crowdsourcing
(using laptops and data centers) at https://github.com/ctuning/ck/wiki/Crowdsourcing-optimization. Finally, you can get open sources of this Android app at
https://github.com/ctuning/crowdsource-experiments-using-android-devices . This development is coordinated by the non-profit cTuning foundation: http://cTuning.org . Please,
check out our other initiatives for open science at http://cTuning.org/reproducibility-wiki .
We have been struggling with a lack of computational resources and diverse workloads/data sets/hardware for our own research to make faster, smaller, more power efficient
reliable self-tuning software and hardware for more than a decade! Indeed, computer systems are becoming very inefficient - it is nowadays not uncommon to obtain 10x speedups,
2x size reduction and 40% energy reduction for popular algorithms (DNN, BLAS, video processing) on latest hardware using so-called autotuning of various algorithm parameters and
compiler optimizations. However, this process is extremely time consuming due to very large design and optimization spaces.
With the help of the non-profit cTuning foundation, we have developed this open source Collective Knowledge technology (CK) to let the community share workloads, data sets,
tools and experimental workflows in an open CK format via GitHub or BitBucket, crowdsource experiments across numerous devices provided by volunteers, classify solutions on the
fly (active learning), apply predictive analytics, exchange knowledge and reproduce results. Our current shared experimental scenarios including GCC and LLVM compiler flag
tuning, and we plan to add automatic OpenCL/CUDA tuning, scalability testing, compiler bug detection and numerical stability analysis (see CK-based interactive report:
http://cknowledge.org/interactive-report )! This application simply queries any available public CK server, obtains experimental pack for your device (such as several binaries
of a shared benchmark with different optimizations), runs it on your mobile device with some random data set and send statistics back to CK server to be processed using active
learning and predictive analytics.
Your participation supports our open science and reproducible research initiatives such as Artifact Evaluation at various conferences (sharing experimental workflows with all
related artifacts and results along with publications in a reproducible and reusable way to be validated by the community):

We have many new ideas and possible projects based on this technology. If you are interested to know more or even participate in our activities, join our growing academic and
industrial consortium, optimize or share your realistic workloads, implement new experiment crowdsourcing scenarios, provide more computational resources, do not hesitate to get
in touch with the author (Grigori Fursin, http://fursin.net) or via our public mailing list:

Thank you very much for participating in experiment crowdsourcing and enabling open science!
