[gin-ops] test matrix and data-intensive application

[Cindy Zheng]

Dear all,

There are a couple of action items from GIN meetings 
since last GGF. One is to setup a test matrix (hello 
world) for all GIN testbed systems. I setup some basic 
tests using SCMSWEB. The tests are set to run hourly
and test each cluster on globus authentication, job 
submission, griftp and DNS. To see the test results, 
click "GIN Testbed Status" on the page 
http://goc.pragma-grid.net/gin/default.html.

This is a quick initial setup and we are working on 
an improvement to SCMSWeb to correctly handle services
running on different addresses within a site/cluster.
For example, gridftp service on ANL cluster is running 
on a different node from gatekeeper service - currently
we are not getting the correct gridftp test results for
ANL cluster. 
Somsak - our SCMSWeb expert at Kasetsart University, 
Thailand has revised SCMSWeb software and is doing
some final testing. We will upgrade SCMSWeb soon and 
will let you know when this problem is fixed.
But the structure for the testing matrix is there.
Let me know any problems and suggestions, and we'll
improve upon this.

Another action item is to try an additional application
to explore data aspect of interoperation issues. 
I'm very happy to introduce to you David Abramson and 
Colin Enticott of Monash University, Australia. David
is the brain behind the development of grid middleware
- Nimrod, which greatly simplifies grid application 
deployment and execution. The application they would 
like to try in our GIN testbed is a climate simulation 
application - Savanah Study. This application is based 
on Nimrod/G and has achieved long-run (a few months)
in PRAGMA Grid testbed. One characteristic of this 
application is more data and data movements, thus it 
makes a good case to study data issues in GIN.

Colin has join our list and will prepare a requirement
page for his application. We will contact each site and
get this application going soon.

Welcome, David and Colin, to our GIN testbed!

Thank you, everyone, for your continued support!
