Our Work
WUR, March 22, 2011
Facilitating Science in The Netherlands with Equipment for
and Expertise on Large-Scale Computing, Large-Scale
Data Storage, High-Performance Networking,
eScience, and Visualization
WUR, March 22, 2011
What We DoOperations● Maintenance of physical infrastructure
● Renewing infrastructure
Support● Help scientists to use the infrastructure
● Consultancy for projects
Development● Services, interfaces, visualization tools, and so on
Innovation● Keep track of developments in the field
● Evaluation of new technologies in pilot projects

How We Do ItAs partner in projects● Usually larger; maybe in time, maybe in amount, maybe in
ambition, maybe in perspective, ...● Roles in organization, reporting, …● “Infrastructure” partners, in the broadest sense
Using resource requests● Typically dealing with one scientist or a small consortium,
solving a certain problem● (Hands-on) support and access to resources● We help with the requests (this is simple!)

● Foundation National Compute Facilities
● Part of NWO, the Netherlands Organization for Scientific Research
● Resource requests for Huygens, Lisa and GPU
WUR, March 22, 2011
● A collaboration between
● NCF● NIKHEF● NBIC● SARA
● Resource requests for Grid, Cloud and Hadoop

Parallelization:Amdahl's Law
WUR, March 22, 2011
Data Parallelization
WUR, March 22, 2011
For exampleBBMRI / Genome of The Netherlands (GvNL)
● Alignment and of sequenced genomes of 750 people
● 750 times the same pipeline of applications
The Virtual Knowledge Studio
● How do categories on Wikipedia evolve over time?
● Periodically look through Wikipedia dumps and build category trees
WUR, March 22, 2011
Task Parallelization
WUR, March 22, 2011
For example
CosmoGrid
● Simulate clusters of stars in a region of the universe
● Everything affects everything
