GridSAM Description

GridSAM is an open-source job submission and monitoring web service. GridSAM is an open-source job submission and monitoring web service. This project is funded by the UK Open Middleware Infrastructure Institute (OMII) commissioned software. The aim of GridSAM is to provide a Web Service for submitting and monitoring jobs managed by a variety of Distributed Resource Managers (DRM).The modular design allows third-party to provide submission and file-transfer plug-ins to GridSAM. Moreover the job management API used by the GridSAM web service can be embedded into grid application that requires job submission and monitoring capabilities.GridSAM endorses the WS-I set of web service standards and the Job Submission Description Language developed in the Global Grid Forum. What's New in This Release: · Added code to forcefully remove working directory and all files therein after a job has completed. · This is enabled by adding deleteWorkingDirCompletely=true to StageOutStatusStage.properties. · This feature is still under test and is disabled by default. · It is useful for when disk space is very limited or when the size of job files are very large. · (See subversion revision 432.) · Refactored the code such that doPBSJob no longer has to be synchronized. · It is instead throttled so a configurable number of job submissions can happen concurrently. · This makes the submission of several jobs at once much smoother, as they don't all block behind the same long lived critical section. · This change affects the the ICT Condor connector, the ICT PBS connector still requires further work to solve this issue. · The level of concurrency can be set by adjusting the max_concurrent_submits property in ICTCondor.properties. · (See subversion revision 429.) · Removed the need to spawn separate threads to read in the output from forked subprocesses. · This should result in faster more efficient execution for this module. · Change from using Runtime.exec to the more modern ProcessBuilder. · (See subversion revisions 427 and 428.) · Added the "-backwards" command line argument to condor_history calls, as this speeds up the lookups considerably on a systems which have a large history. · This is presumably as condor_history always iterates through the past jobs in order until it finds the one in question. · We are always interested in recent jobs, so this change makes sense. · (See subversion revision 425.) · Create and reuse a single instance of DefaultFileSystemManager for use with the ICT DRM connectors. · This fixes a significant resource leak issue. · (See subversion revision 424.) · Make the Condor submission file names and the shell used configurable. · These need to be configurable specifically in the case where the execution nodes are Windows rather then Unix. · The .origin files need to be named .bat and the #!/bin/sh line needs to be removed. · (See subversion revision 423.)
