  2. What is the PoC environment? is a shared, common environment, where different tools and services are both used and provided by the VL-e community PoC Release n Release Candidaten+1 Developers environment Stable, reliable, tested Cert. releases Grid MW & VL-software Flexible, test environment Characteristics Flexible, ‘unstable’ Virtual Lab. rapid prototyping (interactive simulation) Test & Cert. Grid MW & VL-software Compatibility Application development Usage NL-Grid production cluster Central mass-storage facilities+SURFnet NL-Grid Fabric Research Cluster DAS-2, local resources Initial compute platform VL-e Rapid Prototyping Environment Environments VL-e Certification Environment VL-e Proof of Concept Environment

  3. The PoC Distribution is set of software that provides a layer of middleware for developing VL-e Grid applications Serves as a reference set of software that is present all throughout VL-e Grid Is released as a set of Linux RPM’s for RHEL3/CentOS3/ScientificLinux3 platforms The PoC Environment is the ensemble of systems running the PoC Distribution The PoC Installer is a setup program wrapped around the PoC Distribution for easy installation and configuration Current version (Alpha): http://poc.vl-e.nl/distribution PoC: Hardware and Software

  5. Grid Certificates • Grid access involves access to many different computer systems in many different sites. With old-style username/password, a unique username and password are required for each computer system. This is too cumbersome for both the end user and the admins; • On the Grid, you will be using a certificate. This certificate binds together your identity (name, affiliation, etc.) and a unique piece of digital data called a “public key” • The use of a public key to authenticate yourself is based on “asymmetric cryptography”. • Where do I apply for a grid certificate? https://ca.dutchgrid.nl/request

  6. Common Questions: • Does it run on Windows? • Short answer: No • Longer answer: Sort of … • Do I really need to use certificates? • Yes, Grid Site administrators need to keep track of who is doing what. Without resorting to giving everybody a unique userid, a different mechanism is required. For this, a PKI and X.509 certificates are used. • Where do I apply for a grid certificate? https://ca.dutchgrid.nl/request
