Note: This version of the VDT (1.6.1) is no longer supported. Feel free to look through the documentation and install it, but we cannot guarantee support for it. The current stable release is 2.0.0.

System requirements for VDT 1.6.1

Operating Systems

VDT 1.6.1 is supported on:

• Debian 3.1 (Sarge)
• Fedora Core 3
• Fedora Core 4
• Fedora Core 4 (x86-64)
• Fedora Core 4 (x86 on x86-64)
• RedHat Enterprise Linux 3 AS
• RedHat Enterprise Linux 3 AS (x86-64)
• RedHat Enterprise Linux 3 AS (x86 on x86-64)
• RedHat Enterprise Linux 3 AS (IA-64)
• RedHat Enterprise Linux 4 AS
• RedHat Enterprise Linux 4 AS (x86-64)
• RedHat Enterprise Linux 4 AS (x86 on x86-64)
• ROCKS Linux 3.3
• Scientific Linux Fermi 3
• Scientific Linux Fermi 4
• Scientific Linux Fermi 4 (x86-64)
• Scientific Linux Fermi 4 (x86 on x86-64)
• Scientific Linux 4 (IA-64)
• SUSE Linux 9 (IA-64)

It may work on other Linux releases, but we do not guarantee it.

The VDT does not support SELinux though some of our supported platforms (Fedora Core 4) come with SELinux enabled by default. Be sure to disable SELinux in /etc/sysconfig/selinux before installing the VDT.

We try to make all software in the VDT work on all of our supported platforms. In the long run we succeed, but there are sometimes problems with newer packages. Additionally, some software packages are starting to drop support for RedHat 7. See our list of known problems and contents list for more information.

Disk space

VDT 1.6.1 takes different amounts of space depending on the subset of the VDT you install. The complete VDT requires at least 1.5GB.

Pre-installed Software

• Pacman The VDT is installed with Pacman. For VDT 1.6.1 we require Pacman 3.19 or greater. Earlier versions will not work.
• Perl The VDT requires perl 5.8.0 or greater.
• tar Any version of tar is fine. We do not require GNU tar.
• diff & patch The VDT uses diff and patch. Any recent versions are sufficient.
• inetd/xinetd Either version of the internet “super-server” must be installed and enabled. Any recent version is sufficient.

Batch system requirements

If you are installing Globus to provide access to PBS or LSF, they will need to be pre-installed. If you will be using the Web Services portion of Globus, the log files for PBS and LSF must be accessible from the gatekeeper node: these log files are read in order to monitor the progress of jobs.

Compatibility Libraries

Given the large number of platforms we support it's unrealistic to build natively on all of them. In most cases a single set of binaries will work just the same, provided that the required compatibility libraries are installed.

Platform	Compatibility Libraries
RedHat Enterprise 4	compat-libstdc++-33
Fedora Core 4	compat-libstdc++-33

When installing Globus-Base-SDK or PyGlobus in 32-bit mode on an x86-64 architecture machine, you need to have the right 32-bit glibc RPMs installed. On RedHat Enterprise Linux 4 AS and Scientific Linux Fermi 4, we have found that 32-bit versions of the following packages are needed:

• glibc
• glibc-devel

RedHat Enterprise Linux 5 AP support

We have tested VDT 1.6.1 on RHAP 5 and verified that it works well, if you follow a few extra steps.

First, when installing, you must supply pacman with the argument '-pretend-platform linux-rhel-4', for example:

# pacman -pretend-platform linux-rhel-4 -get http://vdt.cs.wisc.edu/vdt_161_cache:Package

Second, the following RPMs must be installed:

• openssl097a-0.9.7a-9
• xinetd-2.3.14-10.el5
• libXp-1.0.0-8

Finally, for sites using WS GRAM, sudo's requiretty setting must be set to off. RHAP 5 may have this option on by default. Look in your /etc/sudoers file for something similar to the below and comment it out:

# grep requiretty /etc/sudoers
Defaults    requiretty

# visudo
# Defaults    requiretty
