Information model / Information discovery
site-BDII, top-BDII, glite-CLUSTER fall into this category.
Refer to the generic criteria on GlueSchema compliance.
Job Execution Appliances
This category covers Computing Elements products (CREAM, ARC-CE, QCG-COMP, ...)
Interaction with the batch system
Job execution appliances must be able to perform basic management jobs in a batch system:
- create new jobs,
- retrieve the status of the jobs submitted by the appliance,
- cancel jobs, and
- (optionally) hold and resume jobs
The Appliance may perform these operations for individual jobs or for set of jobs in order to improve its performance (e.g. for retrieving the status instead of querying each of the individual jobs, do a single query for all jobs submitted for the appliance)
Verification must be performed for at least one of the following batch systems:
- Torque/PBS
- SGE/OGE
- SLURM
- LSF
How to test
- Submit simple jobs (e.g. sleep for a couple of minutes) to the Job Execution Appliance and check:
- the jobs are correctly executed in the batch system
- the status of the job is retrieved correctly and in a timely manner (i.e. status may not be updated in real-time, but it should be available within a short period of time)
- cancel the jobs in the Appliance removes the job in the batch system
- Submit jobs with some input/output files and assure that the files are correctly transferred.
Sample jobs for some CEs are available at https://github.com/enolfc/egi-qc/tree/master/tests/jobexecution
Multi-node/multi-core jobs
Job Execution Appliances should support multi-node/-core jobs. Different support modes are considered:
- multi-slot request: the job specifies the number of slots, which will be allocated following a default policiy defined by the site (e.g. filling up machines, using free slots of any machine, etc.)
- single-machine multi-core request: the job specifies number of required slots that get allocated within a single machine.
- multi-node multi-core request: job can specify the number of cores and the number of hosts to use (e.g. 4-cores at 2 different hosts)
- Exclusive request: job request specifies the hosts to be used exclusively.
How to test
Submit jobs for testing the different modes listed above and check in the batch system that the allocated slots are as specified.
Sample jobs for some CEs are available at https://github.com/enolfc/egi-qc/tree/master/tests/jobexecution/
Parallel jobs (with mpi-start)
mpi-start should be able to detect the batch system and execute parallel jobs with different MPI implementations.
How to test
Submit mpi-start jobs with different slot requirements (see possible cases in the multi-node/multi-core test), using different parallel jobs (dummy, MPI and OpenMP), and check that:
- mpi-start detects the batch system
- input and executables is transferred to the nodes involved in the job
- MPI execution works without issues

Storage Management Appliances
This category covers Storage Elements products (DPM, dCache, StoRM, ARC-SE,...)
SRM compliance
Execute tests with a SRM client that:
- pings the SRM interface
- creates a directory
- puts a file in that directory using different transfer methods (gsiftp, http)
- gets back the file
- copy file
- moves file
- removes file
- deletes files and directory
How to test
Sample test using the StoRM SRM client is available at XXX
lcg-utils test
Perform various operations using the lcg-* commands that use the SRM interface.
How to test
Sample test is available at XXX
WebDAV
If the SE supports WebDAV, execute the following operations:
- create directory
- list directory
- put file
- get file
- copy file
- move file
- remove file
- remove directory
How to test
