  • 1. Large-Scale Scientific Computing in The NetherlandsEvert.Lammerts@SARA.nl WUR, March 22, 2011Lykle.Voort@SARA.nl
  • 2. ProgramIntroducing SARA & Computing (15 slides)● Our Work● Large-Scale ComputingDiscussion● What you do● What we can do together WUR, March 22, 2011
  • 3. Our WorkWUR, March 22, 2011
  • 4. 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
  • 5. What We DoOperations● Maintenance of physical infrastructure● Renewing infrastructure Project BasedSupport● Help scientists to use the infrastructure● Consultancy for projectsDevelopment● Services, interfaces, visualization tools, and so onInnovation● Keep track of developments in the field● Evaluation of new technologies in pilot projects WUR, March 22, 2011
  • 6. 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 senseUsing 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!)
