Draft SE Schema
by Laurence Field 12 Jun '07

12 Jun '07

Hi, Please find attached an initial draft of the SE schema. This is an attempt to consolidate all the input which I have received. It is important that we define the main entities and the relationship between those entities as soon as possible, so please focus on that rather than the individual attributes. The attributes should be used as a guide to what the main entities are. I will arrange a phone conference next Thursday 31 May, so that we can dicuss this futher. Thanks, Laurence

GLUE2.0's Computing Element
by Gerson Galang 06 Jun '07

06 Jun '07

Hi all, Can you show me how to represent the setup I have below using the new structure of the GLUE 2.0 entities? - our site manages 2 clusters - each cluster runs a PBS queuing system - each queueing system manages three queues: small, medium, large - globus is installed on a separate box -- called the gateway box. we run only one instance of the GRAM service on this box. anyone running a grid job at our site will have to specify the name-of-queue@name-of-pbs-server in the queue element of their RSL to pick which queue they want to submit their jobs to. It is not mentioned anywhere in the InitialSketch wiki (http://forge.gridforum.org/sf/wiki/do/viewPage/projects.glue-wg/wiki/Initia…) that the CE is still an abstraction of a queue. The relationship of a ComputingService to a CE is also many to one which makes it hard for one GRAM service to be able to submit jobs to a number of CEs (if ever a CE is still equivalent to a queue). Does this mean that we will have redundant info for the ComputingResource, ExecutionEnvironment, and ApplicationEnvironment for every GRAM service (for each queue) we provide? Is it safe to assume that the ComputingResource, ExecutionEnvironment, and ApplicationEnvironment entities in GLUE 2.0 are equivalent to the Cluster, SubCluster and Software entities of GLUE 1.3 respectively? You have a comment in the form of a question under the "element" section of the wiki which says: "can we have multiple resources (computing resources <=> clusters) served by the same service instance?". My answer is yes and isn't my use case above an example of it? Thanks, Gerson

Use cases from SAS
by Christopher Smith 05 Jun '07

05 Jun '07

As I mentioned at OGF20, I've been working with SAS on defining some use cases that we'd like to see addressed within the HPC Profile or some extension to the HPC Profile. For the information side of these use cases, perhaps we can see how the GLUE schema can address them. I've attached a use case document that Doug Haigh from SAS shared with me earlier this year. From the GLUE perspective, please ignore the job control operations as these would be addressed in an extension to BES, not in GLUE. Perhaps I can go over these use cases in the call next Thursday if there is time and if people wish. -- Chris

GLUE 2.0 Computing Resource directories
by JP Navarro 09 May '07

09 May '07

The GLUE 2.0 Compute Resource entity has 3 attributes that point to directories: TmpDir, ScratchDir, DataDir. Computing resources may have node local, cluster wide, and grid wide scratch. Grids may also have other types of directories that they would like to publish like project directories, parallel file system directories, etc. It would be useful to have a separate "Compute Resource Directory" entity that makes it possible to publish other directory types besides "Tmp", "Scratch", and "Data". Perhaps an entity called "Computing Resource Directory" with 2 attributes: <Type> = "Tmp", "Scratch", "Data", or other IDs <Path> = the path to the directory Thanks, JP Navarro
