System requirements for VDT 2.0.0


VDT 2.0.0 is supported on the following platforms:

Operating System Architectures Pacman Name for OS
CentOS 5 x86, x86-64 CentOS-5
Debian 5 x86-64 Debian-5
Red Hat Enterprise Linux 5 AP x86, x86-64 RHEL-5


VDT 2.0.0 used to be supported on more platforms, and you can still install VDT 2.0.0p35 (the version as of February 28, 2012) on the following set of platforms. However, when we provide software updates to the VDT, these platforms will not receive any updates.

Disk space

VDT 2.0.0 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


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

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.

CentOS 5compat-libstdc++-33
Red Hat Enterprise Linux 4compat-libstdc++-33
Red Hat Enterprise Linux 5compat-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:

Platform-specific notes

SuSE 9 - IA64

On SuSE 9 IA64 (but not x86-64), you will need to install the python-xml rpm
