Scientific computing in The Netherlands
0 likes474 views
This document discusses large-scale scientific computing in the Netherlands. It introduces SARA, the Dutch national high-performance computing center, which facilitates science in the Netherlands through large-scale computing, data storage, networking, visualization and other resources. SARA supports scientists through infrastructure maintenance, consulting, developing new services and tools, and tracking innovations. SARA works with scientists on projects and through resource requests to help solve large-scale computing problems.

- 6. How We Do It As 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!)
