get_cluster_configurations [‑filter <arg>] [‑regexp] [‑nocase] [‑quiet]
    [‑verbose] [<patterns>]


Name Description
[-filter] Filter list with expression
[-regexp] Patterns are full regular expressions
[-nocase] Perform case-insensitive matching (valid only when -regexp specified)
[-quiet] Ignore command errors
[-verbose] Suspend message limits during command execution
[<patterns>] Match cluster configuration against patterns Default: *


Gets a list of cluster configurations that includes Vivado default cluster configurations and cluster configurations created using the create_cluster_configuration command.

Vivado supports the following cluster management tools.

  • Load Sharing Facility (LSF)
  • Sun Grid Engine (SGE)
  • Simple Linux Utility For Resource Management (SLURM)


-filter <args> - (Optional) Filter the results list with the specified expression. The -filter argument filters the list of objects returned by get_cluster_configurations based on property values on the cluster configurations. You can find the properties on an object with the report_property or list_property commands. Any property/value pair can be used as a filter. In the case of the cluster configurations object, "TYPE" and "IS_DEFAULT" are some of the properties that can be used to filter results.

The filter search pattern should be quoted to avoid having to escape special characters. String matching is case-sensitive and is always anchored to the start and to the end of the search string. The wildcard “*” character can be used at the beginning or at the end of a search string to widen the search to include a substring of the property value.
Note: The filter returns an object if a specified property exists on the object, and the specified pattern matches the property value on the object. In the case of the "*" wildcard character, this will match a property with a defined value of "".

For string comparison, the specific operators that can be used in filter expressions are "equal" (==), "not-equal" (!=), "match" (=~), and "not-match" (!~). Numeric comparison operators <, >, <=, and >= can also be used. Multiple filter expressions can be joined by AND and OR (&& and ||). The following gets a default cluster configurations with name lsf:

get_cluster_configurations * -filter {IS_DEFAULT == 1 && NAME =~ "lsf"} 

Boolean (bool) type properties can be directly evaluated in filter expressions as true or not true:

-filter {IS_DEFAULT} 
-regexp - (Optional) Specifies that the search <patterns> are written as regular expressions. Both search <patterns> and -filter expressions must be written as regular expressions when this argument is used. Xilinx regular expression Tcl commands are always anchored to the start of the search string. You can add ".*" to the beginning or end of a search string to widen the search to include a substring. See for help with regular expression syntax.
Note: The Tcl built-in command regexp is not anchored, and works as a standard Tcl command. For more information refer to

-nocase - (Optional) Perform case-insensitive matching when a pattern has been specified. This argument applies to the use of -regexp only.

-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
Note: Any errors encountered on the command-line, while launching the command, will be returned. Only errors occurring inside the command will be trapped.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
Note: Message limits can be defined with the set_msg_config command.

<patterns> - (Optional) Match cluster configuration names against the specified patterns. The default pattern is the wildcard * which gets a list of all defined cluster configurations. More than one pattern can be specified to find multiple cluster configurations based on different search criteria.

Note: You must enclose multiple search patterns in braces, {}, or quotes, "", to present the list as a single element.


The following example gets the list of all cluster configurations.


The following example gets the cluster configuration with name 'lsf'.

get_cluster_configurations lsf

The following example gets the list of all default cluster configurations.

get_cluster_configurations -filter {IS_DEFAULT}
