== Agenda ==

The dial-in number for this call (Wednesday April 20th, 9 am PDT [noon EDT]) was sent out in email.

The agenda will cover some of the points raised in an email thread within the Engineering core related to grid infrastructure and the LONI pipeline:

# Overview of goal and potential timelines
# LONI pipeline overview
# Grid architectural issues
## authentication
## exporting jobs (single job vs. entire pipeline)
## resource discovery
### compute resources
### application resources
## workflow optimization
# Compute resources available for the programmer's retreat
# Action items...

== Minutes ==

'''Attendees: Bill Lorensen, Steve Pieper, Mike Pan, Jeff Grethe, Jason Gerk, Simon Warfield'''

* Discussions on security
** Jeff discussed BIRN's utilization of GSI and how the BIRN authentication architecture and services allow for single sign on across multiple resources
** Michael discussed the Pipeline's use of J-DRAMMA and how the Pipeline server connects to the SUN Grid Engine as the pipeline user and how client's could be made to connect to other remote resources directly

* Bill suggested a 'staging grid' for compiling code and running continuous/nightly tests of algorithms on large sample data sets
** Requires the ability to stage newly compiled applications to compute resource without hands-on administration
** Three levels of applications under development were mentioned in the context of utilizing grid resources to aid the development process
*** Development - application run locally
*** Testing - nightly builds will require the dynamic staging of applications
*** Production - application can be installed in a permanent location in standardized distribution

* Next Call
** A follow up call next Wednesday at same time (April 27th, 9am PDT/noon EDT)
** Continue the discussion of job launching and authentication. More specifically, how would the Pipeline talk to grid resources - 1) does the client connect directly to the resource and how does the client get the module information; 2) does the server connect and how does authentication get passed through

* Action Items
** Compute resources for Programmers retreat
*** Jeff and Jason will confirm that BIRN compute resource will be available, also will

check with Phil P. about possible additional fallback resources

* ** *** Mike will check with LONI about availability of compute resources
