Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is(More)
In high-energy physics, terabyte and soon petabyte-scale data collections are emerging as critical community resources. A new class of " Data Grid " infrastructure is required to support distributed access to and analysis of these datasets by potentially thousands of users. Data Grid technology is being deployed in numerous experiments through(More)
At a recent meeting of monitoring experts from nine large supercomputing centers, there was a broad divergence of opinion on what monitoring in our environment actually is, what ought to be monitored, what technology should be used, etc. Broad consensus can be summarized in a couple of key points: • Data management is increasingly a problem. As a(More)
Computational science applications are driving a demand for increasingly powerful storage systems. While many techniques are available for capturing the I/O behavior of individual application trial runs and specific components of the storage system, continuous characterization of a production system remains a daunting challenge for systems with hundreds of(More)
