Shared gram_condor_log

Burt asked about VDT Support Ticket #1123, in which he seems to have a shared gram_condor_log: multiple user jobs share it, but it's only writable by a single user, and this causes failures. Alain is still looking into it, and coordinating with Burt

GridFTP log and MonaLisa

In VDT 1.3.7, the shift to Globus 4 moved the location of the GridFTP log file from $GLOBUS_LOCATION/var to $GLOBUS_LOCATION/var/log. Unfortunately, Monalisa looks for it in the former location. For VDT 1.3.8 we'll put a link to it so that MonaLisa can find it in either location, and we'll note this as a known problem in VDT 1.3.7.

PRIMA

Vikram asked about the 64-bit pre-web services build. Alain from the VDT team has been working on it, and he told Vikram exactly the changes he's made so far. It still doesn't work, but progress is being made. The changes are:

• Change nmi-remote-build.pl to detect if we are on a 64-bit platform. If we are, then also build 64-bit Globus core, and invoke nmi-build.sh with an argument to indicate that it's a 64-bit build.
• Change nmi-build.sh to use 32 or 64 bit Globus libraries, as appropriate.
• Fix libtool in the OpenSAML directory to work on 64-bit platform. The first attempt at this failed, another attempt is in progress. Hints for this came from an OpenSAML mailing list.

Vikram is waiting for a new build from the VDT to deal with an authorization problem that is holding up the web-services version of PRIMA. Alain told him that it's not hard to build a one-off version of Globus with the approrpriate fix, and it will be faster than waiting for the VDT, which has to get a real patch from the Globus folks.
