End User Data Scheduling with PDMS

Abstract

The Proactive Data Management System (PDMS) [13] is a tool designed to manage large datasets in grid environments. It can be used by other higher level software tools in a secure fashion to manage files based on metadata describing the contents of the files. This document describes how PDMS can be used with tools that schedule the movement of data to and from the resources that use or produce the data. The rest of the document is laid out as follows. Section 2 describes the PDMS inter- faces. Section 3 explains the workflows and meta-schedulers and shows how PDMS can be integrated with the workflow managers. Section 4 explains the Virtual Data Toolkit and integration of PDMS with it. Finally, the document is summarized in Section 5.
