OSG Scalability, Reliability and Usability

The Open Science Grid is relying on several network facing services to deliver resources to its users. In order to avoid unexpected structural service problems, OSG has established a working group dedicated to testing the scalability and reliability of the services it uses. This team tests both existing and proposed software packages up to (and possibly slightly beyond) scales expected to be reached in the foreseeable future, evaluating and documenting both the response times and the failure modes.

This page provides an aggregation point of the above mentioned activity.
