If you are interested in Mapreduce or Hadoop I recommend submitting to or attending the following workshop.

The Third International Workshop on MapReduce and its Applications (MAPREDUCE’12)
June 18-19, 2012 HPDC’2012, Delft, the Netherlands.


Since its introduction in 2004 by Google, MapReduce has become the programming
model of choice for processing large data sets. MapReduce borrows from functional
programming, where a programmer can define both a Map task that maps a data set
into another data set, and a Reduce task that combines intermediate outputs into
a final result. Although MapReduce was originally developed for use by web
enterprises in large data-centers, this technique has gained a lot of attention
from the scientific community for its applicability in large parallel data
analysis (including geographic, high energy physics, genomics, etc..).

The purpose of the workshop is to provide a forum for discussing recent advances,
identifying open issues, introducing developments and tools, and presenting
applications and enhancements for MapReduce (or very similar) systems. We
therefore cordially invite contributions that investigate these issues, introduce
new execution environments, apply performance evaluations and show the
applicability to science and enterprise applications.


– MapReduce implementation issues and improvements
– Implementation optimization for GPU and multi-core systems
– Extensions to the programing model
– Large-scale MapReduce (Grid and Desktop Grid)
– Use of CDN and P2P techniques
– Heterogeneity and fault-tolerance
– Scientific data-sets analysis
– Data and compute-intensive applications
– Tools and environments for MapReduce
– Algorithms using the MapReduce paradigm


Authors are invited to submit full papers of at most 8 pages, including all
figures and references. Papers should be formatted in the ACM proceedings style
(e.g., Submitted
papers must be original work that has not appeared in and is not under
consideration for another conference or a journal. Accepted papers will be
published by ACM in the conference workshops proceedings.

Papers should be submitted here: TO BE ANNOUNCED ON WEBSITE


– Manuscript submission deadline : February 25, 2012
– Acceptance notification : March 26, 2012
– Camera-ready paper deadline : April 16, 2012
– Workshop dates : June 18-19, 2012

If you are interested in search I recommend you to consider submitting a paper to or attending the Searching 4 fun workshop* (I just joined as a program committee member) which is going to be held in Barcelona in April 2012.

Call for Papers
The topics of the workshop will be evaluation focused and include but are not be limited to:

  • Understanding information needs and search behaviour in casual-leisure situations.
  • How existing systems are used in casual-leisure searching scenarios.
  • Systems / Interfaces / Algorithmic approaches to supporting Search in Casual-leisure situations.
  • Use of Recommender Systems for Entertaining Content (books, movies, videos, music, websites).
  • Modelling of users interests and generation of accurate and appropriate user profiles.
  • Interfaces for exploratory search for casual-leisure situations.
  • Evaluation (methods, metrics) of Casual-leisure searching situations.

We are seeking short 2-4 page position papers in this area, or short papers reporting early or formative results in the area of searching for fun.

Reviewing and Publishing

Papers will be reviewed by an international program committee, and we intend to publish the accepted papers using the CEUR Workshop Proceedings service.


Participants should submit anonymised 2-4 page ACM format PDFs to the easychair page. More details are in our submissions page.


Program Committee

We’ll be using the #search4fun hashtag where possible
(ECIR Conference Twitter account is @ecir2012)

The prior update of this posting was in May, and a lot has happened related to Mapreduce and Hadoop since then, e.g.
1) big software companies have started offering hadoop-based software (Microsoft and Oracle), 2) Hadoop-startups have raised record amounts, and 3) nosql-landscape becoming increasingly datawarehouse’ish and sql’ish with the focus on high-level data processing platforms and query languages.

Personally I have rediscovered Hadoop Pig and combine it with UDFs and streaming as my primary way to implement mapreduce algorithms here in Atbrox.

Best regards,
Amund Tveit (
