VDT 1.3.11

We are in the final testing phases of fixing little problems with this latest VDT release. Some of the final tasks include:

  1. We have solved the problem with segmentation faults with our new 64-bit Fedora Core 4 release. We had to rebuild some software so that it does not use portions of OpenSSL that are programmed in assembly. This took a significant amount of time to track down and fix. We have submitted a request to Globus to upgrade OpenSSL to a newer version, which we believe will obviate this problem in the future. In the meantime, we are using OpenSSL's C code, which might make some operations slower.
    Globus Bugzilla 4617
  2. Globus web service still has been problematic on a small number of platforms. We have solved all problems except for two. One of them we hope to have a fix for the remaining issue by the end of today. We are discussing the other problem with the Globus RFT team, and will hopefully have a workaround for soon.
  3. We have been adding small features to the CEMon configuration process based on requests from John Weigand and the RESS team.
  4. We have decided to postpone support for running 32-bit binaries on 64-bit Fedora Core 4. We will return to this problem after the 1.3.11 release because we think the main customers for FC4/64-bit (LIGO) care only about 64-bit mode.
Again we believe we will have a release by the middle of next week. We are thankful for the community's patience while we work through this difficult release.

Prima

There was some light discussion between Alain Roy and Vikram Andem about problems with building PRIMA on 64-bit Fedora Core 4. It was decided that this will investigated after the 1.3.11 release because LIGO is the only user of this platform combination at this point and they do not use PRIMA in the LIGO Data Grid.
