VDT 1.4.0 Release

On September 6th, 2006, the VDT team announced the release of VDT 1.4.0.

This release is nearly identical to 1.3.11, except for some bug fixes.

Upgraded Software since 1.3.11

• Condor/Condor-G 6.8.1
• NMI Build and Test 2.1.7
• PPDG Cert Scripts 2.0
• PRIMA Authorization Module For GT4 Web Services 0.1.2

Bug Fixes

• (VDT Ticket 1727) A memory leak in GUMS was fixed. This did not require an update to GUMS, but a change in it's Axis configuration. This was the same memory leak that was frequently discussed in Open Science Grid.
• (VDT Ticket 2144) PRIMA-GT4 was updated to fix a problem where it caused the GT4 container to steadily increase the number of threads it had.
• (VDT Ticket 2111) A minor problem in vdt-system-profiler was fixed.
• (VDT Ticket 1993) The missing gums-service command (a client tool) was added.
• (VDT Ticket 2003) osg-info-gums-status-probe.sh (part of the Generic Information Provider) was updated.
• (VDT Ticket 2076) A performance problem with CEMon and the Generic Information Provider was fixed.
• (VDT Ticket 2077) The configuration for CEMon was fixed, and it prevents a script from being run more frequently than needed.
• (VDT Ticket 2089) Debuging output in SRM-V1-Client was turned off by default

Other Changes

• The recommended version of Pacman changed to 3.18.5.
• When Condor is installed, it sets HOSTALLOW_WRITE to be the hostname of the computer you are installing on. It used to be "*", which would let anyone in the world submit jobs to your Condor. This new setting might be more restrictive than you want, but you can edit it in condor/etc/condor_config.

Known Problems

• If you install Globus, you should install the Globus-Security-Update-1 package after you install it. More information
• If you install VOMS, you should install the VOMS-Security-Update-1 package after you install it. More information
• The CEMon Server, while available for all platforms, is not tested on all platforms. This is because the CEMon Client has not been built on all platforms.
• In our testing of Condor-G with the Globus pre-web services fork jobmanager, a simple job ('echo "Hello"') occasionally failed to return any bytes for standard out. Other tests of Condor-G passed all the time. Making the fork job take longer by wrapping the echo command in a shell script with a sleep(30) before and after made the problem go away. We are still investigating the root cause of this problem, which occurred only on some machines and only on some tests.
• We are unable to support 32-bit installations of the VDT on SUSE Linux Enterprise Server 9 running on Itanium processors. We advise our users to use the 64-bit version. We will investigate the problem further for the next release.
