Reproducibility-as-a-service: can the cloud make it real?

Kenji Takeda, Solutions Architect and Technical Manager with Microsoft Research, has written a blog post on Recomputability 2014, as well as discussing some of the issues (and potential opportunities) for reproducibility in computational science we have outlined in our joint paper (including a quote from me):

This is an exciting area of research and one that could have a profound impact on the way that computational science is performed. By rethinking how we develop, use, benchmark, and share algorithms, software, and models, alongside the development of integrated and automated e-infrastructure to support recomputability and reproducibility, we will be able to improve the efficiency of scientific exploration as well as promoting open and verifiable scientific research.

Accepted papers and programme for Recomputability 2014

I am co-chairing Recomputability 2014 next week, an affiliated workshop of the 7th IEEE/ACM International Conference on Utility and Cloud Computing (UCC 2014). The final workshop programme is now available and it will take place on Thursday 11 December in the Hobart Room at the Hilton London Paddington hotel.

I will also be presenting our paper on sharing and publishing scientific models (arXiv), as well as chairing a panel session on the next steps for recomputability and reproducibility; I look forward to sharing some of the outcomes of this workshop over the next few weeks.

The workshop Twitter hashtag is #recomp14; you can also follow the workshop co-chairs: @DrTomCrick and @npch, as well as the main UCC account: @UCC2014_London.

Call for Papers: Recomputability 2014

I am co-chairing Recomputability 2014, the first workshop to focus explicitly on recomputability and reproducibility in the context of utility and cloud computing and is open to all members of the cloud, big data, grid, cluster computing and open science communities. Recomputability 2014 is an affiliated workshop of the 7th IEEE/ACM International Conference on Utility and Cloud Computing (UCC 2014), to be held in London in December 2014.

Recomputability 2014 will provide an interdisciplinary forum for academic and industrial researchers, practitioners and developers to discuss challenges, ideas, policy and practical experience in reproducibility, recomputation, reusability and reliability across utility and cloud computing. It will provide an opportunity to share and showcase best practice, as well as to provide a platform to further develop policy, initiatives and practical techniques for researchers in this domain. Participation by early career researchers is strongly encouraged.

Proposed topics of interest include (but are not limited to):

  • infrastructure, tools and environments for recomputabilty and reproducibility in the cloud;
  • recomputability for virtual machines;
  • virtual machines as self-contained research objects or demonstrators;
  • describing and cataloging cloud setups;
  • the role of community/open access experimental frameworks and repositories for virtual machines and data, their operation and sustainability;
  • validation and verification of experimental results by the community;
  • sharing and publication issues;
  • recommending policy changes for recomputability and reproducibility;
  • improving education and training: best practice, novel uses, case studies;
  • encouraging industry’s role in recomputability and reproducibility.

Please see the full call for papers; deadline for submissions (online via EasyChair) is 10 August 2014 17 August 2014.

Bezos’ Law

The future of cloud computing is the availability of more computing power at a much lower cost; Moore’s law thus gives way to Bezos’ law:

Over the history of cloud, a unit of computing power price is reduced by 50% approximately every three years.

 
The cost of cloud computing should naturally track Moore’s law (as the cost of computing is related to the cost of hardware); however, the cost of utilities such as electricity clearly do not follow the same demand curve. Nevertheless, with Amazon Elastic Compute Cloud, Google Compute Engine and Microsoft Azure increasingly competitive on pricing, cloud, as opposed to building or maintaining a data centre, would appear to be a much better economic delivery approach for many companies.

Cloudy with a chance of rain

According to a recent survey by Citrix*, many Americans appear to be utterly confused by cloud computing. While the cloud phenomenon is clearly taking root in our mainstream culture, there is still a wide gap between the perceptions and realities of cloud computing. While many use it, few understand it: 95% of people surveyed claimed they have never used the cloud, 22% admit that they have pretended to know what the cloud is or how it works. Nearly one third see the cloud as a thing of the future, yet 97% are actually using cloud services today via social networking, email, file sharing, banking and online shopping.

But the big stat is: 51% of respondents, including a majority of Millennials, believe stormy weather can interfere with cloud computing.

* FYI, Citrix is a software company that specialises in virtualisation, networking and cloud technologies, so you can see the potential angle of this survey; plus it was a relatively small sample size (c.1000).
