Title: GridWay DRMAA 1.0 Implementation - Experience Report

Authors: J. Herrera, E. Huedo, R. Montero, I. Llorente

Abstract: This document reports about experiences made with running
DRMAA working group compliance test for C bindings against GridWay 5.2
implementation of the Distributed Resource Management Application API
(DRMAA). GridWay (www.gridway.org) is an open source meta-scheduling
technology that, on top of Globus services, performs job execution
management and resource brokering. GridWay performs all the job
scheduling and submission steps transparently to the end user and
adapts job execution to changing Grid conditions by providing fault
recovery mechanisms, dynamic scheduling, migration on-request, and
opportunistic migration.

This document also includes some implementation details of the DRMAA
API, and remarks some special considerations made to implement the
DRMAA standard on a Grid (Globus based). The main difficulties arise
because the nature of the Grid itself, as opposed to a classical
Distributed Resource Management System (DRMS), which provides a single
system image where all resources are in the same administration
domain.
