Notes on registration

For:  employees

The ZID requires information about the computer to be backed up. This guide will help you identify this PC information. 

The information on the CPU is used to calculate the license fees incurred. Enter the data in the registration form.

Linux

Host name

The host name is the name of your PC in the network of the University of Vienna or worldwide. To apply for a backup account, your computer must have a valid host name (DNS name). You can find the host name of your PC on the system information website or contact your IT representative.

CPU model

To find out the CPU model, type in the following command:

cat /proc/cpuinfo | grep "model name" | uniq

Number of built-in CPUs

The number of CPUs installed on the motherboard is normally (personal PC, laptop): 1 

If you want to register a virtual PC for the central backup, a higher value could also be correct here:

  • If you are not the operator of the virtual infrastructure, ask them how many CPUs are installed on a motherboard.
  • If your machine runs in the virtual infrastructure of the ZID, enter 2.

Number of the host’s cores

To find out the number of cores (without hyper threading), type in the following command:

cat /proc/cpuinfo | grep "cpu cores" | uniq

Windows

Host name

The host name is the name of your PC in the network of the University of Vienna or worldwide. To apply for a backup account, your computer must have a valid host name (DNS name). You can find the host name of your PC on the system information website or contact your IT representative.

CPU model

To find out the CPU model, type in the following command:

wmic CPU get Name

Number of built-in CPUs

The number of CPUs installed on the motherboard is normally (personal PC, laptop): 1 

If you want to register a virtual PC for the central backup, a higher value could also be correct here:

  • If you are not the operator of the virtual infrastructure, ask them how many CPUs are installed on a motherboard.
  • If your machine runs in the virtual infrastructure of the ZID, enter 2.

Number of the host’s cores

To find out the number of cores (without hyper threading), type in the following command:

wmic CPU get NumberOfCores

To register a virtual machine, enter the assigned cores here, not the number of cores owned by the installed CPU.

macOS

Host name

The host name is the name of your PC in the network of the University of Vienna or worldwide. To apply for a backup account, your computer must have a valid host name (DNS name). You can find the host name of your PC on the system information website or contact your IT representative.

CPU model

To find out the CPU model, type in the following command:

sysctl -n machdep.cpu.brand_string

Number of built-in CPUs

The number of CPUs installed on the motherboard is normally (personal PC, laptop): 1 

If you want to register a virtual PC for the central backup, a higher value could also be correct here:

  • If you are not the operator of the virtual infrastructure, ask them how many CPUs are installed on a motherboard.
  • If your machine runs in the virtual infrastructure of the ZID, enter 2.

Number of the host’s cores

To find out the number of cores (without hyper threading), type in the following command:

sysctl hw.physicalcpu
