Daily Lab / POC Activities

Extramural:

We had a great meeting with Ron Price from Utah. We discussed some of the reasons he choose to use caGrid ( http://www.cagrid.org/wiki/CaGrid:Software:Release:1.0 ) over Globus. The main reason for choosing caGrid over Globus was that it removed some of the complexity when it came to creating grid services. The underlying technology of caGrid is Globus, but it comes with tools that aid in grid service development.

Ron currently has three grid nodes running caGrid. We discussed methods for connecting the two grids in order to run a grid to grid federated query. One way to do this is sharing our trusted CA information and the trusted CA hash file to the /etc/grid-security/certificates directory. This will be tested later.

We also discussed using PURSE for our certificate management. Ron mentioned this was a popular certificate management application used by other grids. I will continue researching PURSE for this purpose.

I also met with Nigel from the University of Chicago. He is interested in getting Medicus to work over the grid. I sent him a copy of our grid node installation document and CA setup information. He currently has a working Medicus installation that he was able to test with internal grid nodes. He agreed to send me his Medicus installation notes. He's going to get an installation update from his Medicus engineer in Peru and we will attempt to test Medicus over next week.
