  1. CICC Project Meeting • VOTable Developed VotableToSpreadsheet Service which accepts VOTable file location as an input, converts to Excel spreadsheet using jakarta’s HSSF(POI Project's pure Java implementation of the Excel '97(-2002 ) http://jakarta.apache.org/poi/hssf/index.html and returns excel file URL as an output. Community Grids Lab

  2. condor • Condor is a workload management system • Users submit jobs to Condor, Condor places them into a queue, chooses when and where to run the jobs based upon a policy, carefully monitors their progress, and ultimately informs the user upon completion Community Grids Lab

  3. We have installed and configured Condor 6.8 on 156.56.104.135 Linux machine. • We are able to submit and execute simple jobs using vanilla universe like, universe = vanilla executable = /home/condor/test.sh output = test.out error = test.error log = test.log Where test.sh can have simple Linux command #!/bin/sh echo $HOSTNAME Community Grids Lab

  4. We have also configured condor-g (window to the Grid) • Condor-g is nothing but a condor uses Globus to provide underlying software needed to utilize grid resources such as authentication, remote program execution and data transfer • Condor-G is a program that manages both a queue of jobs and the resources from one or more sites where those jobs can execute. It communicates with these resources and transfers files to and from these resources using Globus mechanisms. (In particular, Condor-G uses the GRAM protocol for job submission, and it runs a local GASS server for file transfers). Community Grids Lab

  5. We are now able to submit globus jobs to gf1, NCSA and SDSC teragrid machines Example executable = test.shoutput = test.outerror = test.errorlog = test.loguniverse = gridgrid_type = gt2globusscheduler = gf1.ucs.indiana.edu/job-managerleave_in_queue = jobstatus == 4queue Community Grids Lab

  6. We are also able to submit globus jobs to gf1, NCSA and SDSC teragrid by advertising classad of machines. Example of classad for gf1.ucs.indiana.edu MyType = "Machine"TargetType = "Job"Name = "condorTest02"Machine = "condorTest02"gatekeeper_url = "gf1.ucs.indiana.edu/jobmanager"UpdatesSequenced = 9CurMatches = 0Requirements = TARGET.JobUniverse == 9Rank = 0.000000CurrentRank = 0.000000OpSys = "LINUX"Arch = "INTEL"State = "Unclaimed"Activity = "Idle"LoadAvg = 0.000000Memory = 2048WantAdRevaluate = TrueStartdIpAddr = "156.56.104.135" Community Grids Lab

  7. And submit description file for classad mechanism universe = gridgrid_type = gt2notification = neverglobusscheduler = $$(gatekeeper_url)executable = test.shtransfer_executable = trueoutput = hg-host.$(Cluster).outerror = hg-host.$(Cluster).errorlog = hg-host.$(Cluster).logrequirements = TARGET.gatekeeper_url =!= UNDEFINEDqueue Community Grids Lab

  8. We are also able to configured condor birdbath to submit jobs through condor SOAP API • Right now we are working on modifying OGCE condor job submission portal code to work with condor 6.8 and globus jobs. • All information about condor installation, setup, job submission and SOAP API is available on http://communitygrids.blogspot.com Community Grids Lab
