Resource Collections & Selection

Documenting the identification of resources and the steps required to gain access will help us build a profile of the computational resources available and the processes by which they can be leveraged for this and other projects.

Please see ContainerManagement for configuration notes for specific containers.

UABgrid

We are developing the workflow with two campus resources cheaha.ac.uab.edu and olympus.cis.uab.edu. As the workflow matures we plan to add other local resources like cahaba.eng.uab.edu, coosa.eng.uab.edu, and emerging Condor pool development efforts.

SURAgrid

We are working through the list of available resources and determining how to request access and what the policies around usage are.

Note: This section will be expanded to cover the steps involved for specific resources. Resource requests from LSU, TAMU, and GSU have been initiated.

TeraGrid

TeraGrid allocates resources to communities of users. A number of these have established Science Gateways which make those allocations available to the users involved in domain specific projects. The most relevant communities of interest for this project include:

The production Renci Portal has just become operational on June 4, 2008. It is evolution of the NCBioportal. This resource was restricted to North Carolina initiatives originally. It's not clear if those restrictions remain, but this is likely a good model for our own state initiatives.

If none of the established science gateways are appropriate, we may need to develop one. Information on this process is available here.

TeraGrid also offers resources for development initiatives as part of their Development Allocations.

Open Science Grid

The Open Science Grid (OSG) is a collection of resources that accessible to a number of computational initiatives. The OSG exposes resources to end users through Virtual Organization (VO) dedicated to specific science domains. There are many established VOs. Setting up a VO is also possible and may be a pragmatic approach to integrating OSG and UABgrid. OSG also supports exploration of their computational model through Engagement VO.

caBIG

It's not clear what computational allocations are available through the caBIG's caGrid infrastructure, but it is likely that this framework is a likely source of compute or workflow support.

Additional Resources

  • NIH Biowulf is a resource available to any researcher with NIH funding. While not a grid-accessible resource, the potential does exist for us to incorporate it into a pool by building a grid-connector that accepts computation for authorized users (eg. a science gateway-like service that submits the researchers jobs to the biowulf and provides grid facing interfaces).
